246Laboratories are considered a fundamental part of the students educational experience in engineering. In the case of chemical engineering, students implement theories and concepts that are related to mass, heat, and momentum transfer. From an educational point of view, Feisel and Rosa[1] have listed the main 13 objectives of engineer ing instructional laboratories: 1) instrumentation practice, data analysis, 5) design application, 6) learning from failure, 7) use of creativity, 8) improvement of psychomotricity, 9) teamwork experience, 12) consideration of ethics (for lab), and 13) sensory awareness. During the lab session, students are usually divided into small groups, and perform laboratory or pilot-scale unit operations experiments under the direction of professors or associate teachers. Students sometimes content themselves with following the steps that are described in the protocol they have been given and do not try to deeply understand the underlying phenomena. This kind of behavior is often said to be a cookbook or follow the recipe approach, as pointed out by McCreary, et al.[2] and Young, et al.[3] As a consequence, students lack motivation for practical work and this leads to poor output, i.e. dents are not eager to take on responsibilities) and rather poor analysis of the experimental results, among other undesirable outcomes. Assuming such behavior, the objectives suggested by Feisel and Rosa[1] of knowledge, and improve integration of concepts, different types of laboratory instruction have been suggested. In his review, Domin distinguishes four different styles of teaching Pilot-Scale Laboratory Instruction for ChE: THE SPECIFIC CASE OF THE PILOT-UNIT LEADING GROUP ANNE-MARIE BILLET, SVERINE CAMY, CAROLE COUFORT-SA UDEJ A UD (expository, inquiry, discovery, and problem-based) that can be differentiated according to three distinct descriptors (outcome, approach, and procedure).

247between styles lead to different learning outcomes. In a more [5] suggest that crosscourse projects can be followed; Jimenez, et al.,[6] propose to focus on open-ended problems within a stop and go course organizationa method that requires students to search for information, to plan experiments, to interpret data, and to derive conclusions. Doskocil[7] recommends combining the design of experiment techniques with a current experiment to present a more real world situation to the student. Felder and [8] game show Survivor, Newel[9] also recommends a method for active learning that addresses students involvement. From the literature on chemical engineering laboratory education, one can see that most of studies are devoted to points 1 to 9 in Feisel and Rosas list while the four last pointswhich are related to communication and managementare scarcely tackled. As pointed out by Jones,[10] Smith,[11] and Johnson and Johnson,[12] however, generic skills such as team management and time management should not be taught only during keyLab work dedicated to chemical engineering practice at platform that gathers various chemical engineering pilot-scale rigs () such as: batch and continuous distillation, liquid-liquid extraction, batch reactor, stirred tank with gas-liquid mass transfer, multiple effect evaporator, gas absorption columns, and heat exchanger. The objective of this lab experience is to have students discover and operate the instrumentation and equipment related to the main chemical engineering operations. Traditional lab practice, however, has shown some weaknesses when derived through the traditional laboratory instruction and this has prompted some instructors to propose an innovative process for managing laboratory instruction. As a result, the idea of a pilot-unit leading group for the chemical engineering pilot-scale laboratory instruction was introduced. The aim of this paper is thus to present the pilot-unit leading group approach that teachers of INP-ENSIACET have put into practice for chemical engineering laboratory instruction. PRESENTATION OF THE CONCEPT AND PRACTICE OF PILOT -UNIT LEADING GROUPThe students involved are in the second year of INP-ENSIACET engineering formation (Chemical Engineering DepartStudents spend six full days in the pilot equipment platform. technical and pedagogical booklets are given to them a few days before the beginning of the lab session. Students are have been taught on the subjects, and to bring with them any documents that may be helpful during the lab session. Pedagogic Objectives The pilot-unit leading group approach has a dual pur pose: concepts learned in the classroom into a coherent learning activity, 2. The second aims at adding some communication and dual approach is integrating the second objective without [13] shift in the control and responsibility of learning from teacher to student, and to promote active participation by the learner. To create such a dynamic learning environment, the educational team at INP-ENSIACET decided to transfer or partially delegate the responsibility of instruction for the pilot-units to the students and let them manage their classmates. At the end of the laboratory session, the assessment must show that students: ing theory to the apparatus, have conducted an extensive and detailed investigation of the pilot plant operation, have gathered, carefully examined, and interpreted the data, have drawn consistent conclusions, have made recommendations based on technical and have developed skills in writing technical reports, oral and written communication, management of groups, and teamwork. Practical Organization The class is divided into six groups of three or four students who work on six pilot-scale operations: liquid-liquid extrac tion, continuous distillation, batch distillation, absorption, stirred tank, and multiple effects evaporator. Each student group uses each pilot during one day. The pilot-unit leading group concept refers to the fact that the students become the managers for the pilot they have been working on during must decide which kind of experiments have to be done by the other students during the lab session, manage the other technical questions of their classmates. To illustrate this concept we chose to focus on the example of a liquid-liquid extraction pilot-scale laboratory that uses water as a solvent to extract acetone from an acetone-cyclo hexane mixture. The process is quite simple and consists of the solvent and the acetone-cyclohexane mixture, a pump to


248 ensure pulsation inside the column, and several tanks for the Schedule of the Formation Day 1 pilot-scale installation that the students have to operate. The main possible experiments that can be performed on the installation are explained. During this day, the students become familiar with the pilot plant. They analyze the apparatus and environment (instrumentation, process control, devices, analytical techniques, etc); then they perform experiments, interpret the experimental results, and put into practice both design models and tools of simulation to better understand the physical and chemical phenomena. In addition to learning the pilot operation, students spend the day in coordination with the teacher answering the different questions that arise such as: At the end of the day, the students have to give the teacher a planning sheet compiling the details (operating conditions) of the experiments they want their classmates (of the other groups) to perform. Special attention must be paid to the coherence of the operating conditions so that each group one operational parameter. In particular, each group must collect a set of experiments that can be interpreted and that also contain at least one or two experiments dedicated to the repeatability and redundancy of measurements. For example, concerning the liquid-liquid extraction laborapulsing frequency and amplitude, can be varied. For each set of operational conditions, students have to determine, at least, the composition of the currents (using chromatography the number of theoretical stages using a triangular diagram. At the end of the day, the planning sheet established by the leading group must gather the operating conditions that will be tested by the other groups. This sheet must be presented using a clear and precise table that can be easily understood by the teachers and the other students. Day 2 During the second day, students discover a new pilot-unit and have three main tasks: 1) Perform the experiments requested by the leading group of the unit on which they are working. 2) Write a report (called a basic report) concerning the results of the experiments and the analysis of the data. This report is given at the end of the day to the pilot-unit leading group of this unit. 3) Manage the group of students working on the apparatus they are in charge of. This last task includes the presentation of the apparatus, the explanation of the experimental schedule, and the management of their classmates all day long. Note that depending on the results obtained by each group, the planning sheet which gathers the operating conditionscan be updated by the leading group at the end of each day, according to the notion of continuous quality improvement (for the so-called Kaizen attitude, described by Ima and Kaizen). End of the session One week after the last day of laboratory class, each group has to give a comprehensive report (called a pilot-unit lead ing group report) concerning the pilot apparatus they had to manage. This work is also evaluated by means of an oral presentation (about 20 minutes). This presentation must recall the principal parts of the report. The assessment tools will be Observed Evolution of Students Behavior The detailed objective of the pilot-unit leading group technique is to lead to the improvement of: the students are expected to : conduct a literature search to collect information con cerning the unit operation design appropriate experiment schedules, design and conduct analytical, modeling, and experi mental investigations interpret their own data and the data of other groups, and then draw conclusions skills. Indeed, all along the laboratory course, students experiment on how to manage a project, which makes them sensitive to their future professional experience. This is an active learning process and a real-time life experience: They have to act as an individual and as a member of a team structure; they have to share responsibilities, assign


249 monitor progress, and integrate the individual contribuand oral presentation). In addition, the pilot-unit leading group experience also delivers a strong message on aspects related to health, safety, security, and professional ethics, thus providing learning portant skills. The feedback of teachers who have experienced this approach, which has been applied at INPT-ENSIACET for several During the laboratory class, students seem to be more concerned by the experiments they have to perform because their results have to be used by their class mates. For example, when there is a doubt concerning the protocol they directly refer to the pilot-unit leading group. They do not hesitate to repeat an experiment that was not reliable enough. If they deviate from the given protocol, they derive in their report a discussion about the observed discrepancies. The involvement of the leading group is excellent. They really take care of their apparatus and seriously consider the management of the other groups. Students learn how to design and to estimate the quan tity of work that can be done by their colleagues in a one-day period. Students also experience how to delegate work to their classmates and how to manage technical staff (manage TEACHING-STAFF INVOL VEMENT/ COMMITMENT The implementation of the pilot-unit leading group concept in the chemical engineering syllabus at INP-ENSIACET has The teaching staff still has the responsibility of: safety and security aspects evaluation of the relevance of operating conditions proposed by the pilot-unit leading group, evaluation of the relevance of methodologies available to address the objectives, evaluation of the assimilation of concepts learned in class.Some new aspects have to be taken into account, however. As pointed out by Lickl,[15] the teachers role is not to be the sage on the stage but the guide on the side. On day one of the pilot-unit leading group laboratory, the teachers role is somewhat traditional: he/she gives explanations of the apparatus, of the relevant parameters to study, of how to run the analyses, etc. During the following days, the teachers major role is to observe (especially concerning the security and safe ty aspects). The teacher must accept that the knowledge has to be delivered to a student by another student, rather than by himself/herself). The teacher must still make sure, however, that all technical aspects and fundamental theories are well transmitted, understood, and applied. As a result, the teacher is involved in discussions with the groups all day long. A real effort has to be made by the teacher concerning possible misconceptions, which have to be checked more or less in real time. For instance, as mentioned before, the leading group can modify, at the end of each day, the planning sheet of the operating conditions in relation to the results obtained by the working group. This can only be done after a discussion with the teacher and under the teachers agreement. Thus, this kind of pedagogy needs a high reactivity from the teacher, but the high motivation of the students is worth it! ASSESSMENT TOOLS Assessment of competencies acquired by the students As previously mentioned, assessment of students perfor mances during pilot-scale laboratories covers several levels of skills and know-how, since the students have to produce differ ent types of reporting during the entire laboratory instruction. Students have to produce a basic report after each pilot-scale for this document are supplied to the students through a lab protocol, in which practical investigations and confrontation of their results with theoretical phenomena are demanded. The students are asked to give this report back to the teaching staff and to give a copy to the group of students (pilot-unit leading group) that is managing the apparatus they worked on. From an evaluation point of view, the objective of this basic report is to check that students have been able to perform the experiments, to observe the main physical phenomena involved, and to make a proper use of their results. As said in the second part of this paper, at the end of the laboratories each student group also has to produce a typewritten report (referred to as the pilot-unit leading report), that contains a broad and complete analysis of the pilot-scale experiments for which they are the leading group. This report must contain several parts: a list of the industrial applications of the considered unit operation and the associated research experimental results of all groups, a critical and detailed analysis of the experimental results, a modeling study concerning at least one phenomenon that takes place within the pilot, and a discussion of the possible improvements that could be made to the apparatus. For this report, supplementary time (one week) is given to the students so that they can compile and analyze all data. Mainly evaluated through this work are the students management capacity and their ability to analyze the experimental results. The students are also expected to


250develop critical evaluation skills on what and why; they Finally, at the end of the laboratory session, the students are required to give an oral presentation (20 minutes) of their pilot-unit leading group experience. This presentation is done in front of the whole class so that every student hears a complete overview of each pilot-scale lab, even those that they have not managed. This oral presentation aims to check the students clarity of expression and understanding, ability of technical awarded is a weighted average of the three assessments. Details of the assessment tools are listed below: Basic report: The evaluation of the basic report is based As an example, the evaluation of students performance for the liquid-liquid extraction laboratory is carried out using the criteria in Table 1, which has been established in connection with the guidelines supplied by the protocol. The last topic of the assessment for the basic report leads to individual marks for the same experiment within a student group. This individual assessment can be a way of rewarding the conscientious students and of penalizing those who are less active. Pilot-unit leading report: The assessment of the pilotunit leading report is built on a different basis than the basic report. For the pilot-unit leading report, the degree of freedom left to the students is more important, since they have to prove their ability to gather, select, analyze, and synthesize experimental data, and this is largely dependant on their capacity to manage other groups on the pilot-scale unit they are leading. As said before, they are also encour the pilot or the pedagogical method. The criteria assessed in the pilot unit leading report are presented in Table 2. The evaluation of this report leads to a global mark for the whole group. Oral presentation: An individual mark for each student is given from the oral presentation. During the oral presentation, students are evaluated on the criteria listed in Table 3 rather than on their technical skills and theoretical know-how that has been attained through the basic and the pilot-unit leading reports.

251to improve instructional and/or practical aspects. In the special case of these pilot-scale laboratories, the students were asked to The six pilot-scale operations chosen for this new kind of teaching had been carefully selected for their ability to be of the type of unit operation that had to be lead during the session had been highlighted on the survey results. As can be seen in the survey report, the application of the pilot-unit leading group approach has met rather enthusiastic reactions from students. CONCLUSION The development and assessment of competencies in engineering education require some innovative approaches to teaching. Through the implementation of the pilot-unit leading group approach, the chemical engineering students at INPENSIACET are provided with active learning activities and opportunities.

253I packaging its Iron City Lager in bottles made of aluminum rather than glass. Advertisements stated that the contents of an aluminum bottle not only got colder faster, but stayed colder longer than the contents of a traditional glass bottle.[1] Despite the fact that the thermal conductivity of aluminum is much higher than that of glass, it was claimed that an aluminum bottle would keep the contents cold for up to 50 minutes longer than a glass bottle would.[2] This claim appears an un-named independent laboratory for Danzka, a Danish vodka producer that began using aluminum bottles at that time.[3] Aluminum bottles are now used by several beverage companies who maintain the gets colder faster claim but have dropped the illogical stays colder longer claim.The myth of the insulating ability of aluminum beverage bottles persists, however, on the Web and elsewhere. Part of the motivation for substituting aluminum for glass appears to be less product loss due to bottle breakage and lower shipping cost due to lower weight.[6] Some beverage companies have also begun using plastic bottles for these reasons as well as for safety at beaches and public events.[7] The claim has been made that plastic bottles stay cold as long as glass and longer than aluminum.[8] University reported at the 2005 Annual AIChE meeting that the contents of aluminum bottles cooled down much faster but also heated up slightly faster than those in glass bottles.[9] Conversely, researchers at Loyolla College found that on heat ing in air, an aluminum bottle kept it contents colder slightly William Clark is an associate professor in the Chemical Engineering Department at Worcester Polytechnic Institute.

254longer than a glass bottle but explained that the two bottles behaved essentially identically because the heat transfer is controlled by natural convection and radiation at the outer surface rather than conduction through the bottle wall in this situation.[10] Calculations they made indicated that thermal conductivity of the bottle material should have little effect cooling in ice water or heating while hand-held. In this paper we report experiments and calculations that quantify the thermal performance of glass, aluminum, and plastic bottles under various conditions and provide an interesting way to teach heat transfer principles. We measured the temperature of water in 16 oz bottles upon cooling in a refrigerator, cooling in ice water, heating in air, and heating while hand-held, and used COMSOL Multiphysics software to illustrate the appropriate heat transfer mechanisms and calculations. Although we undertook this investigation as a senior project we believe our methods and results can be readily applied to teaching heat transfer fundamentals via a course project, a laboratory exercise, or a class demonstration. While this problem has particular appeal to some students, it should be noted that students should be at least 21 years of age to appreciate it fully. EXPERIMENTAL minum and glass; Miller Lite, plastic) were drained, rinsed with water, and air dried. Number 3 rubber stoppers were sliced longitudinally halfway through to accommodate ther mocouple wires that were extended into the bottles to a height were used with National Instruments interfaces connected to Labview software for continuously monitoring and recording the temperature of each bottle.

255A small (2 cubic ft) refrigerator that was otherwise empty plastic rack and were not touching the walls or each other to minimize conduction. Duplicate measurements were made with bottles in different positions within the refrigerator to determine if bottle placement affected the results. Measurements were also made with two of the same type of bottle in the refrigerator and with two thermocouples in the same bottle. Heating in air was studied by removing the bottles from the refrigerator and placing them on a plastic rack in the room. Cooling in ice water experiments were conducted by simply submerging each bottle up to the neck in an ice water bath. Heating while hand-held experiments were conducted with one person holding one bottle in each hand after the bottles were removed from the ice water bath. Over the course of the experiment, the subject placed the bottles on a shelf intermit tently, rubbed the hands together to warm them, and alternated which hand held which bottle, but care was taken to ensure that each bottle was held for the same length of time. ANALYSIS We assume that the bottles can be considered as cylinders of the appropriate diameters with the heights adjusted to yield effective heights of the bottles are shown in Table 1. Heat transfer through the bottle material can be described by with boundary conditions at the inside and outside walls given by: i, accounts o, accounts for convection in an air (or water) layer surrounding the bottle and for heat transfer via radiation. We have simpli direction only, assuming insulation boundary conditions at the top and bottom of our cylinders as shown in Figure 1a. This assumption renders our 2-D axially symmetric model to be equivalent to a 1-D model since the temperature will be uniform in the axial direction. We prefer the visual representation of the 2-D model, however, and believe it provides a better physical feel for the problem. For example, it is easier to visualize the area available for heat transfer in 2-D axial symmetry than in 1-D. While not technically precise, with simple analysis explains the observed trends in our data sufbottles that include an equivalent stagnant air or water layer at the outside surface of the bottle. Physical properties used for this layer, the water in the bottles and the ice water bath, and the bottle materials are included in Table 1. solve Eq. (1) and give a visual representation of the calculated temperature in the bottles as a function of time and position. We also drew the glass and aluminum bottles more accurately as shown in Figure 1b and considered heat transfer through the rubber stoppers and the air above the water in the bottles. We found that modeling results were substantially the same with those geometries as with the equivalent cylinder models. RESULTS AND DISCUSSION Cooling a glass bottle in a refrigerator. The solid line in Figure 2 shows the measured temperature as a function of time inside the glass bottle upon cooling in the refrigerator. It took about 8 hours for the beverage to reach the control temperature experimental results was always present and appears to be To understand the heat transfer process, we began by attempting to model it with conduction-only, with the tem refrigerator (imagining that there is enough cold air and cooling power c b a T ( o C) Time (s) Figure 2.

256within the refrigerator that the temperature at the bottle surface is constant). That is, we used a constant temperature boundary condition of T = Trefrigerator instead of Eq. (3) and considered conduction through water inside the bottle with a continuity boundary condition at the inside wall instead of the boundary condition of Eq. (2). This is clearly incorrect, but some students think this way initially and it is instructive to illustrate the fallacy and correct it incrementally. As shown in curve a of Figure 2, this severely under predicted the time required to come to thermal equilibrium with the refrigerator temperature. incorrect because the air around the bottle heats up when the warm bottle is placed in the refrigerator. The air some distance away from the bottle will be at Trefrigerator, but not the air at the bottle surface. It should be clear that introducing a stagnant air layer around the bottle, where T decreases from Tsurface to Trefrigerator differences brought about by temperature differences in the air near the bottle will result in natural convection-circulation result in improved heat transfer over that of a truly stagnant air layer. Complicating matters even further is the fact that tribution for objects being cooled in a refrigerator.[11] Rather than deal with all the complexities of this process in detail, Eq. (3) is used as a boundary condition at the bottle surface o, accounting for contributions from resistance to heat transfer across an outer air layer, natural convection in the air layer, and thermal radiao to be about 9 W/m2 K. Using this in the boundary condition of Eq. (3) instead of a constant temperature boundary condition, but still assuming conduction only inside the bottle resulted in curve b of Figure 2. Natural convection also occurs inside the bottle and is better modeled using the boundary condition of Eq. (2) than by conduction-only with a continuity boundary condition. As explained in the Appendix we estimated the inside heat transi 2 K and including that along with ho, as described above, we obtained curve c in good agreement with the experimental data. In this case, the thermal conductivity of the water in the bottle was increased 1000 fold in the model ensuring that all the resistance to heat transfer on the inside of the bottle was lumped into hi. Analysis of the results from Figure 2 indicates that the largest resistance to heat transfer is from the gives a measure of the relative importance of convective and conductive heat transfer. A common rule of thumb is that a due to convection dominates the heat transfer process to the extent that resistance to heat transfer due to conduction is negligible. When applied to the bottle wall, as shown in Table 2, small enough that the bottle wall should not affect the process and the wall temperature will be essentially uniform. This point can be illustrated clearly by modifying our model to include conduction through an equivalent stagnant air layer appended to the outer edge of the bottle wall. Note that air outside the bottle will be in motion due to natural convection, but there will always be a boundary layer near the bottle surface where the dominant heat transfer mechanism is conduction. e, of the equivalent stagnant layer (effective thermal resistance layer) that we envision is not necessarily a physically measurable length out from the bottle surface to a point where T = Trefrigerator, but instead is given as the length Rearranging this equation as ho e provides a physical thermal conductivity, k, of air as 0.025 W / m K, an effective air thickness of 0.00278 m is required to match our ho value of 9 W / m2 K. Including an air layer of this thickness in an refrigerator boundary condition at the outer edge of the air layer reproduced curve b in Figure 2. To obtain curve c in Figure 2 using our equivalent conduction-only model, we used Eq. (5) to determine that conduction through a thermally resistant water layer with thermal conductivity of 0.6 W / m and thickness of 0.0015 m is equivalent to using hi 2 K. It appears that convective mixing inside the bottle results in an effective thermal resistance layer only 1/20th as thick as the bottle inside radius. The rest of the water in the bottle is considered to have a very high thermal conductivity so that it will have T ABLE 2 Cooling in Refrigerator and Ice Water Cooling in refrigerator Cooling in ice water ho(W/m2K) ho(W/m2K) aluminum 10 200 glass 9 0.013 200 plastic 9 0.016 200 0.356


257uniform temperature and pose no further resistance to heat transfer in this model. An alternative approach that perhaps gives a better feel for the convective mixing going on inside the bottle and provides the same temperature vs. time result (curve c) is to use a moderately high thermal conductivity for all the water in the bottle. An effective thermal conductivity of 12 W/m K (increasing the water thermal conductivity 20 fold) was required for this approach. The heat transfer rate by conduction through a composite material is given by Figure 3. Predicted temperature proles in the radial direction for our conduction-only model with effective outside ther mal resistance layer of 0.00278 m and effective inside thermal resistance layer of 0.0015 m at three times (60, 600, and 6000 s) for cooling with outside T = 0 C and initial inside T = 25 C for four cases: (a) glass bottle, air outside; (b) glass bottle, water outside; (c) aluminum bottle, air outside; (d) aluminum bottle, water outside. Note that the r-axis begins at r = 0.025 m in these gures.where the resistance to heat transfer due to each material j is given by and Aj is the area available for heat transfer into material j. Our equivalent conduction-only model provides a visual representation of the resistance to heat transfer given by the effective outside air layer (representing the outside heat transfer coefas shown in Figure 3a where the predicted temperature is plotted as a function of position in the radial direction for three different times: 60, 600, and 6000 s. It can be seen that the


258effective outside air layer gives the largest resistance (largest temperature drop) and that conduction through the bottle wall has little effect. Note that combining Eqs. (5) and (7) indicates that the resistance outside the bottle equals 1 / (hoAo). We can also use the built-in post-processing features of COMSOL and use Newtons law of cooling, to evaluate the value of ho represented by the air layer. For account the bottle outside surface area of 0.03381 m2 yields a value of ho near 9 as expected. Cooling a glass bottle in ice water. matic difference between cooling methods for a glass bottle. since it takes less than 1.5 hours to make the contents ice cold. from the higher thermal conductivity of water compared to air. Our equivalent conduction-only model was used to illustrate this point by assuming, as an approximation, that a 0.00278 m layer of water rather than air was controlling the heat transfer at the outside of the bottle. Simply using the properties of water instead of those of air in the outer layer of our previous model yielded the predictions shown in Figure experimental data exactly, it does show that the difference in thermal conductivity of water and air accounts for most of the difference between the two cooling processes. Comparing Figures 3a and 3b we can see that the resistance to heat transfer offered by the ice water layer is much less than that of the air layer. We can also see that the resistance in the bottle wall is ice water is no longer less than 0.1 as shown in Table 2. An experienced heat transfer teacher might argue that knowing the uninitiated. 0 5 10 15 20 25 0 5000 10000 15000 20000 25000 30000 T o C Time (s) refrigerator ice water Figure 4.

(a) experimental results; (b) predicted results with ho = 200 W/m2K, hi = 400 W/m2K.Comparison of various bottle materials. At this point some ing in a refrigerator and heating in air are shown in Figure 5. Comparing Figure 3a for glass and Figure 3c for aluminum indicates that the resistance to heat transfer in the air outside of the bottles represented by ho dominates the process in both cases. Therefore, it is no surprise that Figure 5b shows the same values of hi and ho for all bottles. Our experimental results, in Figure 5a, show that the aluminum bottle always cooled and heated slightly faster than the other two, however. It appears that other factors, like differences in condensation on the bottles and differences in emissivity, that we have not taken into account are needed to explain why the aluminum bottle cools and heats slightly faster. Increasing the values for ho for the aluminum bottle allowed us to more closely model cooling in the refrigerator (and similar results that would be obtained for heating in air) indicate that wall material should have minimal effect on these heat transfer processes. Experimental and calculated results for cooling the three bottles in ice water are shown in Figure 6. The ice water cool theless, our simple model results, shown in Figure 6b, indicate that the difference in bottle materials does account for some of the observed difference in cooling rates. The resistance to heat in Table 2 help explain why the bottle material has a more in air. Figures 3c and 3d show our equivalent resistance-layer conduction-only model results for the aluminum bottle in air and water, respectively. The small thickness and high thermal conductivity of the aluminum bottle yield little resistance to with the relatively small resistance offered by the water layer in Figure 3d. The thermal conductivity of plastic is less than that of glass, but the wall thickness of the plastic bottle is also for the plastic and glass bottles. For glass and plastic, but not for aluminum, the resistance due to the wall does slow down the cooling process in the ice water case. The fact that the aluminum cools faster will only have pracis reached. The temperature when the mountains turn blue is [12] In ice water, the aluminum bottle will reach that temperature faster than the glass bottle will; how much faster will depend on the starting temperature. in Figure 6, it was about 5 minutes faster, but for a starting 8 minutes faster. This advantage for the aluminum bottle is counteracted by the disadvantage that the aluminum bottle as shown in Figure 7, on the next page (plastic results were similar to those for glass). To give students a physical feel for the heat transfer process, bottle with ice water and have them hold each one. The aluminum bottle feels colder because it conducts heat away from the hand more readily. This explains why aluminum cools faster in ice water and heats faster when hand-held. It might also explain why the myth persists that aluminum keeps beverages colder longer since aluminum feels colder even when the


260contents are the same temperature. Having students place their hands next to the two bottles without touching them allows the students to note that the air gap between the hand and the bottle prevents the faster heat transfer to the aluminum that was observed when the hands touched the bottles. Students will also recognize that room-temperature water feels colder than room-temperature air because the water conducts heat away from the body faster. CONCLUSIONS The experiments and calculations presented here were both fun and informative. They were an excellent way to reinforce our understanding of heat transfer processes. When cooled in a refrigerator, bottle material has little effect on the cooling rate and about 8 hours is required to cool a 16 oz bottled beverage. We recommend an ice water bath for 1 to 1.5 hours (depending on the starting temperature) if rapid cooling is desired. In this case, plastic and glass bottles behave similarly because the lower thermal conductivity of plastic is offset by a thinner wall. If time is of the essence, an aluminum bottle in an ice water bath will reach a satisfying temperature several minutes faster than the other bottles due to the high thermal conductivity and thin wall of the aluminum bottle. The aluminum bottle will warm faster than the others when pend on how rapidly the beverage is consumed. We suspect that the thermal performance of the bottle will not have a major effect on beverage enjoyment, but our studies on this aspect are ongoing.

262The design and synthesis of a pharmaceutical agent that is able to induce the desired biological effect is a research area that requires expertise outside a regular undergraduate chemical engineering curriculum (i.e., structures and functions of cells, protein, and receptors). Although concepts such as intermolecular forces would sound familiar to a chemical engineering student, a lack of basic understand ing of signal transduction pathways would render the task of identifying suitable drug targets insurmountable. Drug delivery using compartmental models, however, is a more accessible option for ChE students with ample training in transport phenomena and especially in solving material balance problems involving singleand multiple-process units. Such perspective is indispensable for a sound understanding of pharmacokinetics, which focuses on drug absorption, distribution, metabolism, and excretion (ADME). In addition to binding properly to receptors and provoking a response, an active pharmaceutical ingredient (API) must be able to [1] Knowledge of pharmacokinetics is therefore critical in drug discovery and the bioavailability and clearance in humans and preclinical species.[2] This information, combined with the recognition of is paramount at a very early stage in the discovery process. The present work describes a series of laboratory experiments, based on principles of chemical processes, to address questions of clinical relevance. Projects that draw analogies between the approach taken to understand the fate of drugs in the body and the methodology adopted to track materials through an entire chemical plant may offer new insights and opportunities to ChE students. Engineering educators have already stressed the need to prepare a workforce with knowledge in drug delivery. Several experiments are made available to help students effectively apply principles of chemical engineering fundamentals (e.g., encing drug release from several delivery devices.[3] Cavanagh DRUG TRANSPORT AND PHARMACOKINETICS For Chemical Engineers LA URENT SIMON, KUMUD KANNEGANTI, AND KWANG SEOK KIM Laurent Simon is an associate professor of chemical engineering and the associate director of the Pharmaceutical Engineering Program at the New Jersey Institute of Technology.

263and Wagner introduced to engineering students hands-on an experimental model of the circulatory system and the concept of drug dissolution. The learning objectives of this contribution are to assist students in i) applying knowledge of mass balances to the design of experiments focusing on the transport of medicaments in the body (learning objective 1), and ii) developing a knowledge of multiple IV doses and continuous IV infusion through well-stirred vessel experi ments (learning objective 2 ). The integration of laboratory activities into the study of drug in chemical engineering as well as for biomedical engineering nology. This three-credit class is mandatory for biomedical engineering students pursuing tracks in biomaterials and tissue engineering or biomechanics and is an elective for chemical engineering students. Concepts of transport phenomena, as applied to biological systems, are presented. Examples of basics of vectors and tensors, conservation relations, and momentum balances. During the semester, students are expected to develop and present simulation-based projects ranging from pharmacokinetic analysis to hemodialysis. Discussions of grasp of real-life implications of several design alternatives and treatment regimens. LABORATORY DESCRIPTION One-Compartment Model and Multiple IV Dosing Regimens The one-compartment model offers the simplest way to describe the kinetics of drug absorption and elimination in a well-stirred vessel (Figure 1). ceutic distributes to rapidly perfused tissues[5] and reaches the systemic circulation instantaneously. In addition, clearance commences immediately after the injection. A mass balance around the process in Figure 1 yields the following differential equation ( learning objective 1 ):[5] or where D is the loading dose, V is the distribution volume, kel is p is the plasma drug concentration at time t, and t is the Dirac delta function. The integration Eq. (2) gives: The elimination rate constant can be computed by measur ing the slope of the straight line: It can be shown that the time required for the plasma drug to drop to one-half of its initial value is: After a single-dose administration, the plasma drug level immediately rises above a minimum effective concentration. concentration drops well below the therapeutic level. Such a situation can be circumvented by prescribing a multiple-dos ing regimen to the patient. This method of administration is not without its own challenge because the impact of each dose on Cp has to be known a priori to achieve optimal clinical effectiveness and to minimize deleterious effects. Experi ments were conducted to help chemical engineering students of the dose, the administration time, and the elimination time constant on the plasma drug concentration. Eq. (3) is used to calculate the plasma concentration at the : Figure 1. Representation of a one-compartment model.

The principle of superposition assumes that early ics of the subsequent doses. Materials and Experimental Procedure 10-mL graduate cylinders, pipettes, rubber tubes, magnetic stirrer, magnetic bars, potassium permanganate, spectrophotometer, cuvettes, laboratory stands, and clamps. The apparatus is shown in Figure 2. The beaker with the KMnO solution was placed on a magnetic stirrer. A pump was used to mimic drug clearance from the body (i.e., waste pump). Water was introduced at a rate similar to that of the waste pump in order to maintain a constant volume of liquid in the with clamps (Figure 2). Two main parameters were adjusted in developing a dosage regime: the size of the dose and the administration frequency. The study demonstrated why the drug strength and dosing interval are important for treatment. After initially adding 10 ml of KMnO to the beaker, a new dose was added every 30 intervals and analyzed with the spectrophotometer. The dose the ease with which samples are collected and the objective of a particular study determine the sampling interval. In this investigation, it was necessary to collect samples at a rela tively fast rate to obtain a full picture of the system dynamics because of the short duration of each experiment. For the seconds. As a result, a sampling period of 15 seconds would allow a student to record the concentration before and after the addition of a new dose. A sample size of 1.3 mL was selected so that a constant volume was maintained in a 200/250 mL beaker. A larger dose would violate the constant volume assumption made in deriving the equations and, therefore, to allow mixing to occur and low enough so that the formainaccurate results. Results and Discussions In practice, each drug has a therapeutic range in the human body. A medicament administered should not exceed the minimum toxic concentration (MTC) or fall below the minimum effective concentration (MEC). The maximum and minimum plasma concentrations should be kept within this window. Figure 3 shows that the dose strengths have a strong impact on Cp min ss and Cp max ss (learning objective 2). As a laboratory project, students can be asked to design drugdosage regimens based on information regarding Cp min ss and Cp max ss. Other hands-on activities may focus on investigating whether the number of doses required to reach a steady state is a function the dose size. Other worthwhile pursuits are to use Figure 3. Concentration of KMnO4 in the central compartment using nine IV boluses and two separate drug sizes: kel = 0.028 sec-1, and = 45 sec, = 0.366 g/L (regimen 1) and = 0.547 g/L (regimen 2). Figure 2.

Bolus Doses Followed By a Constant-Rate Infusion Drugs are administered intravenously in the form of a bolus dose or infused relatively slowly through a vein into the plasma at a constant or zero-order rate. One of the main advantages of an IV infusion is that an effective constant plasma drug concentration can be achieved, thereby eliminatthe injected bolus dose takes 5 to 15 minutes to be completely diluted in the bloodstream,[1] a slow infusion is preferred, in some cases, to prevent an adverse effect caused by a high plasma drug concentration. sion (k0 in unit of mass/time) ( learning objective 1 ): For a constant volume and Cp(0)=0, the solution is: The steady-state concentration: is essentially achieved when t=5 t1/2. One of the consequences of this relationship is that medicaments with long half-lives take a long time to reach a desired steady-state level (or to be within a known therapeutic range). As a result, one of the the drug level is in a prescribed range. A continuous infusion ensues immediately to maintain an effective constant plasma concentration ( learning objective 2 ). during the multiple-dosing phase. Note that the value at the end of the last period N is given by: where is the dosing interval. The solution to Eq. (10) with for the constant-infusion period: Materials and Experimental Procedure The volume of liquid in the central compartment was kept at 200 mL. In one set of experiments, four boluses of KMnO were administered at one-hour intervals followed by a constant-rate infusion. Operating conditions and kinetics obtained in a constant-rate infusion study were applicable in this case ( i.e., kel -1,Cpss=2.0 g/mL, k0=5.6 g/min). Samples of KMnO solution were collected from the central compartment every 15 minutes until the concentration reached the steadystate value. Results of this investigation were compared to a different dosage regimen where two boluses were used prior to the continuous infusion. Results and Discussions of the multiple doses plus the infusion is a distribution of the total amount of injected medicament during the therapy.[6] The increase in the dimension of the input space, however, makes Several researchers have worked on such problems and proposed several algorithms to address the issue. Students should be given the opportunity to estimate the best injection times, drug dose sizes, and infusion rates. The sum of squared errors for the two and four boluses plus infusion are 0.306 and 0.576, respectively. SUMMARY OF EXPERIENCES or programs, that provide an introduction to pharmacokinet ics and drug transport. For example, in the case of IV bolus injections, not only do students need to understand that the blood concentration decreases faster for drugs with a shorter half-life but also why this process is important to patient demonstrated to foster a better understanding of graduate courses in pharmaceutical engineering and some aspects of Figure 4.

266current drug-delivery practices. In Spring 2009, three out of mens. One group of students investigated the effects of drug half-life and multiple-dosing regimens on the maximum and minimum plasma drug concentrations. Another assignment focused on the impact of pharmacokinetic parameters on drug concentrations in the central and peripheral compartments of a two-compartment model. Simulations were also conducted to address several aspects of a continuous drug infusion (e.g., time to achieve steady-state). The students from this group welcomed the idea of incorporating laboratory data from the of time constraints and the fact that some of the laboratory materials/experiments were not available at the time, students requests for conducting multiple-dosing experiments were not met. Nevertheless, the entire class attended a demonstration in the laboratory on IV bolus experiments using well-stirred vessels. Initial responses indicated that the transition from simulation-based to experimental projects (learning objective 2) would be well-received. CONCLUSIONS Several experiments were proposed to help chemical engineering students understand pharmacokinetic processes using familiar continuous-stirred vessels. In line with the educational objective of applying knowledge of fundamental physical principles (learning objective 1), these activities made extensive use of curriculum topics, such as mass balance equations and process dynamics, in an attempt to build on existing knowledge and to reinforce concepts taught in manganate were monitored in a one-compartment stirred-tank dose strengths and administration periods were investigated. The constant-rate infusion, although preferable to bolus injec tions for some medicaments, presents its own challenges, e.g., the plasma drug concentration takes a long time to reach a steady-state. Experiments were designed to enable students to use their knowledge of process dynamics in developing drugdosage regimens that meet certain criteria. Combined with multiple boluses, a continuous infusion may be appropriate for a series of drugs and treatments (learning objective 2). Designed laboratory activities would allow students to appreprotocol. After participating in a demonstration of IV bolus injections, students, who worked on simulation-based projects in drug transport, were very supportive of the addition of a REFERENCES 1.

267The material that is commonly taught in chemical engineering design for engineering economics could be described as risk free, in the sense that the economic uncertainty. The teaching of concepts in economics is usually focused on the treatment of the time value of money (i.e., e.g., return on investment, net present worth), and the calculation of equipment cost and plant cost. Uncertainty is usually associated with limitations of the engineering models used to estimate the cost of the major pieces of equipment in the plant. For example, the students are taught that the models used to calculate the heat transfer area for a heat exchanger are based on semi-empirical correlations and, thus, the estimated cost of a heat exchanger might be inaccurate. The uncertainty about raw material and product prices, about the cost of energy and about labor cost, and the fact that the actual values might depend on factors that are outside of an engineers control (e.g. landscape) is not usually emphasized. In fact, not only most textbooks in chemical engineering design but also most textbooks on engineering economics used within other engineering disciplines offer the same risk free are, of course, quite important for quantifying the economic feasibility of an engineering project, but the availability of sion making calls for an update of the instruction material. Recently, some effort has been placed on the introduction of risk analysis in chemical engineering design.[1] Uncertainty as well as other important concepts such as decision tree analysis and utility functions, however, have not been part of a typical undergraduate curriculum. Lately, through collaboration between the University of Oklahoma Department of Chemical Engineering and Department of Economics, we have developed classroom games that demonstrate concepts such as strategic decision making, the winners curse, and the utility function in Design Ia course that introduces engineering economics to chemical engineers who lack an extensive economics background. In this paper, we discuss the development of these games (or class experiments, as they would be called in the economics literature) and the educational objectives of each game. We also demonstrate the basic components of these games and we discuss the mechanics of carrying out experiments in the classroom. The concepts that are visited with the games can be used to quantify risk and facilitate decision making under uncertainty. TAKING FINANCIAL UNCERTAINTY INTO ACCOUNTUncertainty and change are pervasive in the careers of new engineers, and mastering appropriate analysis techniques and cept for the students to grasp is the incorporation of uncertainty the drilling of an oil well (this is an example offered in detail [2]) or the rolling INTRODUCING DECISION MAKING UNDER UNCERTAINTY AND STRATEGIC CONSIDERATIONS IN ENGINEERING DESIGN GEORGIA KOSMOPOULOU, CHINT AMANI JOG, MARGARET FREEMAN, AND DIMITRIOS V PAP A V ASSILIOU Georgia Kosmopoulou is the Edith Kinney Gaylord Presidential Professor at the Department of Economics at the University of Oklahoma.

268 out of a new product line. A company cannot be sure in advance whether it should be done and what the costs are going a probability density function can be obtained with discrete is then given as where N is the number of possible outcomes, Pi is the probi outcome i. In the examples that follow, the choice of the values of the discrete probability function was made arbitrarily. In practice, however, one cannot generate the probability density function in a rigorous statistical manner, since one cannot be placed in the same business conditions and be faced with the same decision possibilities repeatedly. A particular business situation usually occurs once, thus, one cannot generate a sample of outcomes given the decisions made. The probability density function is usually generated after brainstorming and after consulting with experts having prior experience in similar situations. In the case of rolling out a new product one needs to use market analysis and surveys, in the case of pricing raw materials and products one needs to use forecasting techniques, and in the case of drilling a well one needs to rely on the opinion of geologists and geophysicists who are experienced in the interpretation of geological data (such as data obtained through seismic analysis or core analysis). Example 1: Assume that if a new product (say raspberrythat it will not catch up in the market, 25% probability that it will get 1% of the competitors market share, 20% probability that it will get 2% of that market, and 15% probability of a 3% additional market share. If the product is not rolled out, the payoffs arising from choices made by the decision maker introduction of a new product is then one should clearly decide to produce the new product, An example like this introduces students to a methodol ogy for taking uncertainty into account, and provides the opportunity to discuss decision tree analysis (see Reference 2, or any other managerial economics textbook, for more on also leads to the opportunity to discuss the utility functions as a way to quantify uncertainty and a way to incorporate the attitude of the decision maker towards risk. This discussion can start in the classroom by considering a case where the the two is much more risky. Example 2: A company can invest in a process that can yield a net present worth (NPW) of $1,000,000 with no risk, and a process that can have either a NPW of $2,150,000 with probability of 50% or a negative NPW of -$50,000 with a 50% probability. The expected NPW for the risky option is In this example, the criterion of maximizing expected NPW sense. The students can see that there might be a company that cannot afford a 50% probability of losing $50,000, especially if this is a small company that could go out of business! The utility function can be used to quantify the attitude towards risk and to justify a decision that is clearly not based on exis It is a function that places a numerical value on happiness, or take different actions for companies and consumers! On Sept. 6, 2007, the student newspaper at the University of Oklahoma campus (The Oklahoma Daily) ran a half-page article entitled Happiness Has a Personal Side with pictures of 10 students and their responses to the question What makes were among the responsesanswers that make good sense to students in the Design class. This article illustrated very nicely that happiness (and the utility function that attempts to quantify it) is subjective, and it was quite effective as a handout for relating the concept of the utility function to each to quantify differences in happiness from different decisions and actions. The ordinal character of a utility allows people $00.20 $100,000 0.25 $50,000 New product No change 1% market share 0% market s h a r e 2% market share 3% market share -$20,000 0.15 $150,000 Figure 1. Decision tree that graphically depicts the probable outcomes of rolling out a new product. The probability of each outcome is shown on the decision tree, as well as the prot or loss if the outcome occurs. The dollar value that appears on each branch is the expected prot that corresponds to the branch.


269 to express their preferences between the no-risk option and the risky option in Example 2 and be consistent in choosing different courses of action. [2] For example, using the numbers offered in Example 1, we can say that the utility function has a value of zero for a loss two arbitrarily chosen numbers would work, so long as the min max is found by determining the probability P for which the decision maker is indifferent between a risky option that includes the extremes and a safe In other words, the person whose utility function is generated in this exercise is equally happy to take a safe bet with a return min and max. In this respect, the decision be based on maximizing the expected utility calculated as ii. To demonstrate to the students the utility function concept and to illustrate how a utility function can be generated, we have prepared a game that can be played by the students in class. The game presents students with a series of two options, one of which is a gamble and the other a safe choice. In Figure 2, we are trying to determine the utility of You need to make a series of choices between Options 1 and 2 and record your choices in the spreadsheet before rolling a fair 10-sided die. Consider your payoffs as the sum of the payoffs from each choice. Option 1: If the die comes up 1, you win $150,000, but if it comes up 2,3,..., 10 you lose 20,000. Option 2: You win $0 no matter what the dice-rolling outcome is. Make your choice between these two options and record your choice by typing 1 or 2 in the appropriate cell in the column titled Record choice (1 or 2) (column D in your Excel Sheet). Option 1: If the die comes up 1, 2, you win $150,000, but if it comes up 3,..., 10 you lose 20,000. Option 2: You win $0 no matter what the dice-rolling outcome is. Again make your choice between these two options and record it by typing 1 or 2 in the appropriate cell in the column titled Record choice (1 or 2). Continue up to the tenth choice having in mind that as you go down the list the probability of a favorable outcome in Option 1 increases by 1/10. roll (1-10). Figure 2. Example of the game that students play in order to determine the value of the utility function of a prot equal to zero (Option 2). Option 1 is a gamble between the two extreme values of the prot, taken from Example 2, with different probability of winning or losing, and thus differ ent expected utility. The expected utility at which the player switches from the safe option to the gamble is the point of indifference and indicates the value of U(0).


270 gamble between U(150,000) and U(-20,000). The players are asked to select their options and to input their selection in the spreadsheet. The game is constructed using Microsoft Excel, which allows the instructor to lock certain cells of the spreadsheet parts of the spreadsheet. Student players cannot input numbers in places that can alter the structure of the game. The students When the game ends, each students utility function for this example has been constructed, and some of the students can e-mail their spreadsheets to the instructor or place their utility function on a memory stick and show it to the rest of the class. At that point a discussion in class can be initiated on whether the person whose utility function is shown is a risk-loving or a risk-averse person. In addition, another discussion can be initiated based on the question of what the games might be. Figure 3 is a typical outcome for the utility function from this game. Having created the utility function, the students can return to Example 1 and apply the maximization of expected utility as a decision criterion. They can calculate the expected utility of rolling out a new product, compare it with that of not changing the production line, and make a choice. This will give students an immediate application of the concepts learned. More impor tantly, it becomes evident that this approach is bound to give different answers for different people, since it is the utility and are taken into account when expected utility is maximized.ATTITUDE TOW ARDS RISK tended to be an application of the risk preferences seen earlier, introducing the ideas of actual and expected values. The game presents students with a series of two opof risk. This game is also constructed using Microsoft Excel so of the excel spreadsheet at the beginning of the game. The expected return for each of the options in the game is Due to the EPAs concern over rising levels of greenhouse gasses, all chemical companies are required to reduce CO2 emission by 15%. For the past few years, Independent Chemical, Inc., has subcontracted another company to process CO2. The cost keeps rising, however, and Independent Chemical, Inc., is considering handling the CO2 capturing in-house. Your consulting company is hired by Independent Chemicals, Inc. They want you to suggest which of the following technology options for CO2 sequestration they should use: Option 1: to their existing facility to capture and store CO2. Option 2: Use gas hydrate technology to transport CO2 and store it in ocean. and record your choice in the spreadsheet before rolling a fair 10-sided die that determines the outcome. Option 1: If the die comes up 1, you win $2,000,000, but if it comes up 2,3,..., 10 you win $1,000,000. Option 2: If the die comes up 1, you win $3,850,000, but if it comes up 2,3,..., 10 you lose $500,000. Make your choice between these two options and record your choice by typing 1 or 2 in the appropriate cell in the column titled Record choice (1 or 2) (column D in your Excel Sheet). having in mind that as you go down the list the probability of the most favorable outcome in both options increases by 1/10. Figure 3. Typical utility function resulting from Game 1. This is the utility function of a risk-averse person, since the value of the utility increases at decreasing rate as the expected return increases.


271the game options. One can clearly see that the expected return for Option 2 becomes higher than that for Option 1 after the fourth choice. As one can see in Figure 5b, however, the risk is higher for Option 2 every single time, until the tenth choice. Figure 5b is a plot of the variation (i.e., the standard deviation normalized by the expected value). If one were taking into account only expected returns, third, and fourth choices, and then switch to Option 2. If one is risk-averse, they would stay with Option 1 even after the fourth choice, preferring to have a lower expected value but assuming a lower risk. The spreadsheet decision, where they can see a plot of the expected value of the return for their choices and of the actual return as a result of the dice rolls. The thick solid line traces the choices made, and can indicate whether the player is risk-loving, risk-averse, or risk-neutral.Figure 6. Typical outcome of Game 3. The thick solid line indicates the expected prot based on the options chosen by this player. This is a risk-averse person, who chooses a lower expected prot with smaller risk. The triangles indicate the actual return based on the outcome of the particular dice roll. Figure 4. Example of the game that students play in order to determine their attitude towards risk. Option 1 is a gamble that has a smaller risk, but it also has a smaller expected prot beyond the fth row. Figures 5. (a, left) Expected prot for options in Game 3; (b, right) corresponding estimate of risk for options in Game 3. The risk is always higher for Option 2, while the expected prot of Option 1 is higher for Option 1 until the fourth choice.


272 At the conclusion of the game, some of the students e-mail the rest of the class (as in Figure 6, previous page). A discussion about whether this would be a curve characteristic of a risk-loving or a risk-averse person can be initiated. A riskneutral person would try to maximize expected payoff as their only objective. Hence, the switch from Option 1 to Option for a potential risk averter, same should be true beyond the can see it for themselves merely by observing each others diagrams and the decisions made. DECISION MAKING IN COMPETITIVE In business, a strategic decision-making process is char payoffs that vary with the outcome of the interaction process. there is also uncertainty about how the competitors will belead to changes in the production level that affect the technical and economic functions of a company. A simple game that can illustrate this concept, and is quite easy to do in class, is the following: The students are asked to write on a piece of paper a number between 0 and 100. The winner is the person who writes down the number that is going to be closer to 2/3 of the average of the number that everyone in class writes. To win in this game one must consider what the rest of the class is going to do and act accordingly. The game is rather easily handled in a classroom situation. Three or four students in the class collect the papers from the students sitting close to them, and they add the numbers on the papers they collect in order to expedite the procedure of calculating the class average. We have played this game with the seniors for several years, and almost every time the winner is a person who writes a number close to 23. The winner is asked to explain their way of thinking, as are other students in the class. Everybody who pays attention in the class understands that if the numbers were written randomly, the average would have been 50. The winner usually thinks that 2/3 of 50 is 33, and thus, since almost everybody, the thinking continues, will write down a number close to 33, one needs to pick 2/3 of 33. That would be a number close to 22 or maybe a little higher than 22, in order to account for those who randomly write numbers without thinking through the problem. It is interesting, and contrary to economic theory, that the winner does not continue the thought process to assume that the rest of the class will reach the same conclusion. If that were the case, one would win if he or she would write down a number that is close to 2/3 of 22. If everybody thought this way, then one needs to pick 2/3 of that number, and after several iterations of this type of thinking, the equilibrium point according to economic theory is to pick the value of zero! The goal of this experiment is to use a game theoretical approach to demonstrate to students how to better understand strategic decisions. A major point that can be made by the outcome of this game is that the decision should be made after considering what the other players are going to do and that the winner is the one who guesses how many iteration levels the competitors will consider. This game serves as a good introduction to the problem of the winners curse arising in common value auctions, which is relevant to engineers when, for example, they compete for design projects or for raw materials. In such cases, the value of the items is common but unknown during the bidding process (e.g., bidding for exploration and production rights in a plot that one does not exactly know the quantity of oil Capen, et al.,[3] a group of petroleum geologists who described the bidding outcome in offshore oil lease sales for the period participating in the auctions during this period, they observed that, in a competitive oil and gas lease sale, or indeed in any bidding situation in which the ultimate value of the object to be won is subject to uncertainty, the highest bidder is the one who has overvalued the prize. In that sense, the winner is the most optimistic bidder, who is systematically overbidding (and losing money on average). This phenomenon was termed the winners curse. It was caused by the failure of the bidders to use the optimal bidding strategy. The optimal bidding strategy should have taken into account what winphenomenon nested within many other applications (engineering contracts, etc.). More importantly, it is a wonderful way to explore with engineering students a very practical case where strategic decision making is crucial, and where under uncertainty. PRACTICAL ISSUES AND STUDENT FEEDBACKThe games presented here can be played either during a 1in a workshop for Experimental Economics held at the University of William and Mary in May 2009, in a Masters-level graduate class of Managerial Economics in August 2009, and in a class of chemical engineering seniors in October 2009. In all cases, the spreadsheets were not available to the students long before the game, in order to avoid biased behavior. For


273The dice rolls can be done by digital means, either generating random numbers in Excel or using a dice-rolling website (e.g., ). In fact, the chemical engineer ing seniors were so anxious to get to the dice rolls that they were using their own dice-rolling software on their laptops. The feedback from the players included some ideas to make the games more fun or more relevant. Instead of making all the choices and then dice rolling 10 times, they suggested that dice rolling should follow after each one choice was made. In to go though this process. It was also suggested to adjust the relevant to the average students income, instead of having Another suggestion was to reward the students according to their winnings, either with class credit or with monetary awards. One would expect that such a change in the format of the game, where the players would have a personal stake in the outcome, would lead to risk-averse behavior, which is consistent with economic theory. The goal of the games, however, is not to explore how the players react to different situations, but to illustrate to the players the concepts of risk and decision making under risk. The response to an anonymous survey of whether participation in the games improved understanding of the utility function and of what is meant by attitude towards risk was that the games were helpful and that they should be incorporated in the class material for Design I. The spreadsheets, as well as the directions for conducting the games, are available to interested colleagues who might want to use them in their classes. The values of the options in the games can be changed according to the goals of each instructor. CONCLUDING DISCUSSION The advantage of running experiments in class, in addition to engaging students in active learning, is the ability to control external factors that may be affecting decision making as they change (e.g., risk, uncertainty). Resources for designing other economics experiments are available on the web, for example through the Veconlab software developed by C. Holt at the University of Virginia or through the EconPort portal [5] Modern developments in economics and management include tools and techniques that address uncertainty, risk, strategic thinking, and decision making in a systematic and quantitative way. Deterministic models for the calculation of net present worth, for example, should be used to introduce uncertainty should be offered. The value of risk can be estimated with techniques like those presented by ODonnell, et al.[1] The calculated risk can be used in conjunction with utility functions, such as those presented in the present work, to adjust the calculated NPW according to the methodology [2] by their certainty equivalent values.

275periences do not require dedicated lab space, students have a simple yet unique experience to link into their evolving understanding of chemical engineering principles. As a result, these learning tools also serve as vibrant, hands-on experi ments with high school students. This latest Desktop Experiment Module focuses on demonstrating heat transfer concepts. The DEMo is versatile so that it can be incorporated into any existing chemical engineering Heat Transfer course as either a quick, illustrative example during a traditional lecture or as a mini experiment to demonstrate conduction through various materials or convection. While there is latitude in the equipment purchased for these DEMos, if an IR surface thermometer is purchased, it serves as an illustrative example of radiative heat transfer as well. Advantages of this hands-on experience include that it is not dependent on the availability of lab space and that students have a unique experience to link into their evolving under standing of chemical engineering heat transfer concepts. An instructor can chose to focus on one or more of the following topics when they adapt this experiment: 1-D steady-state conduction, composite systems, contact resistance, thermal energy generation, heat diffusion equation and boundary contions. Coupling the demonstrations with exercise problems in which students must look up properties, assess thicknesses of materials, etc., also adds practical grounding to homework assignments. Course materials including a supply list, example exercises, and experimental procedures are discussed and are available for instructor use via a website.[5] DESKTOP EXPERIMENT MODULE enced below are familiar to the reader. Supplies and Setting Up These supplies will need to be ordered some time in advance. Total cost for 10 stations is about $650.

Thermal conductivity of different materials can be demonstrated as well. Problems can be set up in which the students have to back calculate to determine the thermal conductivity of the material from the two surface temperatures and distance information. Further, composite systems can be examined via wood, Styrofoam, and drywall sandwich blocks. The choice of materials is such that it spans a wide range of thermal conductivities as demonstrated in Table 1.[1, 7]Experimental Procedure:1. Turn on mug warmer with the block of material posi tioned on top and allow the system to heat up for 15 minutes. 2. Check the temperature at the top surface of the material three times at 30-second intervals to ensure the system has reached steady-state. 3. Check the temperature at the surface of the mug warmer once the system has reached steady-state. Note that this may be greater than the steady-state temperature of the mug warmer when exposed only to convection in the air. 4. Replace with new blocks of material allowing it to equilibrate between temperature readings.

276 Analysis: The heat diffusion equation for 1-D, steady-state conduction with constant thermal conductivity is as follows: The general solution is as follows: experiment. The following example uses data for a polycar bonate block 1 cm thick. Polycarbonate was chosen because it wont soften or melt on the mug warmer surface. The particular solution is in symbolic and numeric form: r f nt each material they study and can then use Fouriers Law to it is possible to calculate the other parameter. Alternatively, generation experiment outlined below. 1-Dimensional Conduction Through Composite Systems Steady-state heat conduction through layers of materials can be accomplished as well by stacking the materials provided in Table 1. The analysis is similar to that outlined above. 1-Dimensional Conduction with Contact Resistance Contact resistance can be demonstrated by using a high the material block from Table 1. A silicone-base heat sink compound is easy to obtain and, when used, it can be assumed to represent perfect contact between the warmer surface and the material block. Comparison with the system outlined above (which has air in the gap between the warmer and the material block) enables the student to back out the resistance due to thermal contact resistance. With access to wood or the metals with a rough edge from cutting vs. a smooth edge after cutting, this can also be illustrated. rf n nt b Obtaining the total thermal contact resistance for the case with and the case without heat sink compound is: r f frn rf nfr t b rfn rt f f t b t b t As demonstrated, in this case of a smooth polymer surface, thermal contact resistance can be neglected as it is a couple of order of magnitudes smaller than the thermal resistance associated with the material. Rough metal blocks are good illustrators of how poor physical contact between two materiHeat Generation Analysis Heat generation can be considered by expanding the system boundaries to include the electrical resistance heating in the plate warmer. Solution of the heat diffusion equation with contransient heat generation or steady-state heat generation. Transient Heat Generation The transient nature of electrical resistance heat generation can be illustrated by simply having the students measure the temperature of the plate warmer with the IR thermometer from when it is turned on until it reaches steady-state. A sample experimental procedure is given and data is provided in Figure 1 for two experiments. If students are too hasty in ending the experiment, they may miss reaching the true steady-state Experimental Procedure: 1. Take initial temperature reading of plate warmer before turned on and record its initial temperature at time 0. 2. Turn on the plate warmer and begin stopwatch at the same time. 3. At 15-second intervals, take a temperature reading of the plate warmer using the infrared thermometer. Make sure to measure at the same location for each reading.


277 4. Continue to take readings until the mug warmer temperature is constant for 45 seconds and reaches steady-state.Analysis: The spatial variations in temperature are not considered in this case, so the heat diffusion equation is just: Assuming that heat generation, q is constant, the solution to this differential equation is: Using the initial condition that the temperature of the mug constant of integration. Therefore the particular temperature distribution expreswarmer temperature. tained that the plate is primarily aluminum, which has a density of and a heat capacity of Heat generation can then be obtained: It can be valuable to discuss with students the case in which, when constant power is supplied to the mug warmer and this translates into constant heat generation from the mug warmer, why the data is curved. Most students will deduce that convection from the surface is being neglected and that this contribution only gets greater as the temperature increases. Steady-State Heat Generation It is possible to determine the steady-state heat generation by performing an energy balance at the surface of the mug warmer. The students will need to consider that all heat generated by the plate is being convected away from the mug warmer and will also need to obtain a valid convective heat mug warmer. Since heat generation is usually expressed as a volumetric generation rate it is important to pay attention to units. Further, electrical heat generation can be estimated via Joule heating in the mug warmers heating coil, which has an electrical resistance, Re, and a current, I. So Energy generated in the plate = energy convected away from plate The thickness of the mug warmers heating coil has to be assumed from the thickness of the unit in use, but L=0.01m is realistic. The students can easily measure the ambient air temperature, and the surface temperature of the mug warmer at steady-state was already obtained. Therefore: r f nn nn tt n ft ttt b Using the well-known electrical relation for Power, P: rf The current can be calculated from the information typically provided on the mug warmer unit. Figure 1. Transient heating of the mug warmer demonstrating transient heat generation.


278 And the electrical resistance can then be obtained through the volume, v, of the warmer plate: r Thermal Contact Resistance Thermal contact resistance can also be illustrated using a room temperature to the fully heated plate warmer, the students can observe the transient heating of the cup. If transient heating has already been covered, however, it is possible to have the student set up the experiment and then conduct lecture or other class activities until the system reaches steadystate. This typically takes about 15 minutes. Experimental Procedure: 1. Allow the plate warmer to heat up and reach steadystate (about 15 minutes to Tss 2. Measure initial temperature of the empty mug inside the cup pointing the IR thermometer at the bottom center surface. 3. Place the coffee cup on the mug warmer and start the stopwatch. 4. At 15-second intervals, record the temperature of the bottom inside surface of the mug. 5. Continue to take readings until the mug warmer temperature is constant for 45 seconds and reaches steady-state. Analysis: Since two thermal resistances exist between the surface of the mug warmer and the bottom surface of the coffee cup, it is not possible to isolate the thermal contact resistance from the ceramic mugs resistance. It can be a valuable exercise, however, to ask students to determine from tables the thermal conductivity (and thus calculate thermal resistance) of the is chosen, the thermal conductivity is usually between 1.3 and 2.15 .[1] Estimating the thickness of the bottom of the cup to be 0.5 cm, the thermal resistance of the cup can be determined to be (per unit area): Using the heat transfer rate obtained from the steady-state heat generation example, one can then solve for the thermal contact resistance: rr f n nrtr b nn n n rr rThis thermal contact resistance is substantial and is the reason that the mug warmer is not able to heat coffee or any liquids to boiling despite its high surface temperature of steady-state. As demonstrated in Figure 2, the inside surface reinforce to the students that reducing thermal contact resistance can be accomplished using contact grease or increasing surface contact between the mug and the warming plate. Heat Transfer from Extended Surfaces (Fins) CPU passive heat sinks are excellent small examples of have copper bases for increased conduction away from the processor. The text by Incropera and DeWitt has a number of example problems using passive heat sinks that help reinforce what the students observe.[1] Experimental Procedure: 1. Allow the plate warmer to heat up and reach steadystate (about 15 minutes to reach Tss this as time 0. 3. Place the CPU passive heat sink on the mug warmer and start the stopwatch. 4.

This system can, however, still be used as an illustrative visual aid cross-sectional area and the following equations are valid for this geometry. The tip is assumed to experience convective heat transfer and so the steady-state, position-dependent temperature distribution with this boundary condition is: r f where and while Ac Convection Convection can be included by using a CPU fan on top of a passive CPU heat sink. Most fans are 3 Pin, 9V, or 12V, which can be connected directly to a 9V battery adapter (can be purchased from RadioShack) by splicing together the red wires and the black wires and ignoring the yellow (control) wire. A 12V fan will simply run at a lower speed on a 9V battery. Videos from YouTube are [8] This section covered demonstrations and student experiments for steady-state, 1-D conduction in both a composite system and considering contact resistance, heat generation from both a transient and steady-state perspective, and heat relatively quick (5 to 8 minutes) while others involving transient temperature changes can take 15 to 20 minutes to complete. Since the same basic materials are used throughout the course to illustrate the different concepts, student faexperiments increases through the semester. The advantage of repeatedly using the same system to illustrate different aspects integrating concepts into a coherent framework.[9] CONCLUSIONSA versatile hotplate conduction and convection system is outlined as a Desktop Experiment Module. These DEMos can be useful tools to introduce students to heat transfer concepts in a complementary fashion to the traditional Heat course structure and content as well as the straightforward desktop experiments, which utilized inexpensive supplies to convective heat transfer from solid surfaces, and radiation. Advantages of this hands-on experience include that it is not dependent on the availability of lab space and students have a unique experience to link into their evolving understanding of chemical engineering concepts.

280Engineering, along with science, has been the engine that drives innovation and will continue to be important in tackling the new and unique transporta tion, environmental, and health problems that we face as a global society. For the United States to stay relevant in the new global economy we must position ourselves to take a lead in tackling these problems and the key is to maintain strength in our human capital.[1] Yet, the United States continues to lag behind other developed nations in the quality students in the United States currently receive their degrees in engineering compared to ~50% in some other countries.[1] Furthermore, nearly 62% of all Ph.D. degrees in engineering granted in the United States in 2007 were to foreign students United States.[2] Continuing on this course will lead to fewer engineers with high-quality skills available to lead innovation in the United States.[1]One major contributing factor to the low number of students receiving degrees in engineering is the two decades of decline in student enrollment in engineering. While there has been some recent improvement in enrollment due to the current global recession highlighting the apparent stability of engineering jobs,[3] the United States is still projected to face a shortage of up to 70,000 engineers in this decade. Recent surveys by the American Society for Quality (ASQ) and the National Academy of Engineering (NAE) suggest that this shortage and decline in engineering enrollment is linked to K students having little knowledge of engineering careers in addition to perceiving engineering as boring.[5] The NAE study further concluded that the money and effort put forth by engineering organizations to combat this problem have had little impact. Overall, what is clear from the literature is that boosting undergraduate enrollment and increasing the number of graduates in engineering are two key parameters in keeping the United States competitive in the global economy of the 21st century and beyond. Thus, additional effort needs to be placed on making the new generation of K students aware of the engineering profession and its versatile contributions to solving many critical global issues.

281The two most common outreach tools used in presenting engineering to the public are 1) professional engineers or engineering faculty spending time in the K classroom to talk about their profession and 2) informal educational programs ( e.g., tutoring) focused on improving students understanding of math and science.[5] Visits from engineering professionals, however, often leave students unable to see a path for themselves to achieve the level of success perceived in their corporate/university visitors. Likewise, tutoring/mentoring outreach efforts often fail to connect K students back to the engineering i.e., heavy focus on math and science. Presented herein is a different approach to introducing K students to and exciting them about chemical engineering, where a required undergraduate chemical engineering (ChE) course project is coupled with a science fair style presentation the University of Michigan (U of M) in groups of four were asked to design and present one original experiment suitable for a high school teacher to use in introducing a basic heat or mass transfer concept to his/her high school science class. Each student group was provided a $25 budget to build their experiment, and local high school students from the Ypsilanti school district were invited into the classroom to experience and judge ChE students design outcome on its ability to engage their interest in engineering as a career choice. This for replication of this unique approach to K outreach. METHODS Project Description. For their course project, students enasked to design an original experiment that would be suitable for a high school teacher to use in introducing a mass or heat transfer principle/concept to students in her/his class. Students were assigned to groups semi-randomly where self-selected were asked to design their experiment such that it can serve to attract high school students to ChE. Experimental design was subject to the following constraints: i) experiment must be feasible; ii) materials/setup cost for the experiment must not exceed $25; and iii) designed experiment must be easily set up in a high school classroom. Each group was required to present an in-class demonstration (demo) of their experiment at the end of the semester to a diverse audience composed of local high school students and teachers and chemical engineer their design. For the written project description, groups were required to include a rationale for the design, a detailed list of required materials, and a description of the experimental setup. In addition, groups were asked to include any experimental measurements taken during the design process, describe all relevant mass/heat transfer equations, and include their expected experimental outcome(s) and conclusions. The in-class demo format was less stringent; groups could have one demo that is reused for multiple sets of judges or multiple disposable (inexpensive) setups. Furthermore, in-class demos could not include the use of any hazardous materials (e.g., organic solvents) or high budget of $25 (see project description) to obtain materials for their in-class demos and given access to a senior engineer within the department to provide guidance on setups and choice of materials. Projects were graded on originality, feasibility for reproduction in a high school classroom, and the quality of the in-class demo. The written report counted for 75% of the total project grade and the in-class demo for 25%. Total project grade was given on a 100-point scale and represented were derived from surveys (Figure 1) administered to guest participants that included high school students (HSS), their teachers, and ChE graduate students and faculty. The survey Figure 1. (A) High school student survey and (B) faculty, teacher, and graduate student survey.

Numerical values from surveys were converted to a 100-point scale and averaged over all surveys assessed via a students t-test with p value < 0.05 considered RESULTS There were 115 students and the project description were available to students by the mass or heat transfer principle as a basis for their design and were encouraged to consult with the course instructor on the scope, scale, and feasibility of their projects. About a third of the groups based their experiments on mass transfer principles, and two teams attempted experiments involving both mass and heat transfer. Ten teams consulted with the instructor on various aspects of their designs prior to the inclass presentation. The average written report score for teams that consulted with the course instructor (78.6%) was not presentation scores (average of all surveys) between mass or heat transfer based experiments. Overall, many student groups offered a unique and fun take on several mass and heat transfer principles. For example, the team with the highest project score designed a simple, yet effective, experiment to illustrate the basic principles a station for HSS to cut through ice using body heat that varying the type of material used (graphite, aluminum, and plastic) and contact area between the body and the material law for heat conduction to 10th-11th graders. For instance, a deeper cut into the ice by a particular material would suggest to the HSS that the material has a higher heat conductivity compared to other materials. The fact that many of the HSS (and at least one ChE faculty) expressed their surprise that graphite conducted heat much faster than aluminum highlighted the success of this particular demo in achieving the project goal. Table 1 lists titles and topics of other noteworthy student-designed experiments. Details of these and other successful projects with instructions for replication in the high school classroom can be found at . There were two major drawbacks to the science fair style to set up demo stations in a way that allowed easy access for judging and 2) the large number of demos requiring access to electricity. These two issues led to brief periods of chaos during project presentation. ASSESSMENT Fifteen HSS from the YPSD school district participated in the project presentation. Of these, 10 were female and eight were Africanimmediately after each demo viewed to ensure an accurate representation of their opinions. Four key questions were used on the HSS survey (Q3 Q6 in Figure 1A) to gauge how successful a groups demo was at introducing and engaging T ABLE 1 Presented The Reindeer Effect The experiment demonstrates the ability of a microwave to provide heat to a system through electromagnetic radiation Molecular Diffusion Through a Porous Medium Dependence of mass diffusivity on temperature Once You POP, You Cant STOP temperature and convection via carbon dioxide in liquid soda pop (visual dem onstration of transfer using balloons)

About two-thirds of the HSS encounters with demos resulted in the HSS feeling fairly to highly excited about or engaged with the viewed presentation. More importantly, 83% of encounters resulted in the HSS feeling they learned something new. Overall, nearly 70% of encounters left HSS feeling fairly to highly interested in engineering. Questions 1 and 7 on the HSS survey were used to gauge how well ChE student designs adhered to the project problem statement and imposed constraints (see the section on Methods). Figure 3 shows that 88% of HSS encounters resulted in a fairly to highly original rating of the viewed likely rating on HSS perceived ability to repeat the viewed demonstration in their high school classroom. school teachers, and ChE faculty members were invited to evaluate the technical aspect of designed experiments and project presentation survey.

284thought, and thoroughnessare summarized in Table 2. Overall, faculty responses to Q1 3 were mostly good to excellent (79 95% of the time). About 82% of the faculty teams encounters with demos resulted in a fairly to highly over 90% of the time, the faculty team responded to Q5 through Q7 with a fairly to highly likely rating, suggesting a general feeling that most student teams were successful in designing an economical experiment that is safe and can be easily reproduced in a high school classroom (not shown). The two HS teachers that participated in the project presentation were also asked to respond to Q7 on the HSS survey. Of the six demos they viewed, the two teachers felt that they could fairly to highly likely repeat three in their classroom, they were neutral on two, and felt they were not likely to be able to repeat one in their classroom. Interestingly, the experiment rated low on adaptability to their high school classroom was also rated neutral on originality and not at all on whether they learned something new or its ability to engage their interest in engineering. Thus, it is possible that their perceived inability to repeat this particular experiment in the classroom is linked to their lack of excitement for the demo. Since the class project/outreach event described herein is new to students enrolled in the format be collected. To this end, the ChE students were sur exam and a second time at end of the Winter 2009 semester (~ untary with responses collected anonymously. A total of 100 students participated in the end-of-term survey and 50 in the T ABLE 2Faculty Team Survey Result for Q1 Q3 Excellent Partial Attempt made Absent Creativity Does the group project or display demonstrate 16.3% 0.0% 0.0% Have the students shown creativity in the 37.2% 18.6% 2.3% 0.0% Thought Is the experiment appropriate for the study of 62.8% 32.6% 0.0% 0.0% 65.1% 27.9% 7.0% 0.0% 0.0% 18.6% 0.0% 0.0% Were the observations and information gained 32.6% 18.6% 0.0% 0.0% Does the data collected justify the conclusion 30.2% 20.9% 2.3% 0.0% Thoroughness 37.2% 11.6% 0.0% Does the project indicate a thorough under 53.5% 25.6% 20.9% 0.0% 0.0% 20.9% 0.0% 0.0%post-fall semester survey (post survey). Three key questions were repeated in both surveys to evaluate potential change in charts comparing the outcome of questions between the two surveys. When asked if their project experience helped their understanding of their project subject matter, 72% of the post survey respondents were highly positive compared to 20% of the end-of-term survey respondents. Similarly, respondents on the post survey showed a greater enthusiasm for HSS par ticipation in their project presentation (80% post-semester vs. 27% at the end of term). Students feeling about having this type of project format in other ChE courses at Michigan like wise shifted in the positive direction with only 20% of responend-of-term survey. The overwhelming improvement in ChE students attitude towards the class project in the post survey may not be representative of the entire class, however, since the 87% participation for the end-of-term survey. Thus, it is plausible that students who previously had a positive view of the class project were disproportionately represented on the post survey. Even if this were the case, however, the views of these students appear to be more positive on the post survey as compared to the end-of-term survey, e.g., only 20 students on the end-of-term survey thought the project helped their understanding of their course material vs. 36 students that felt the same way on the post survey. A set of questions was asked only on the post survey to on the outcome of their winter semester courses. Of the 50 students taking the post-semester survey, 38 indicated they


285were currently enrolled in the junior ChE lab course, and 32% was highly valuable to their winter lab course (Figure 5). that their ChE project experience was highly valuable to other courses in which they were currently enrolled. When asked how likely they were to consider participating in other K outreach programs if their class project presentation were categorized as outreach, 60% of post-survey respondents indicated they were highly likely to do so compared to only 8% indicating they were not likely to participate. Overall, students who had a positive feeling about the course project on the post survey did so regardless of their course grade outcome, e.g., worse than expected compared to 20% saying they do not want to see this sort of project in other engineering courses. Finally, some ChE students offered positive opinions about the class project outside of the survey questions. For example, one student wrote the class project showed us how diverse the things are that we chemical engineers can actually do and another said I got the opportunity to talk about the class project at an interview so I was glad that we did the project. Comparison to other science fair style outreach proMany universities (and companies) also have on-site outreach programs that allow K interaction with college students and professionals. Two prominent examples of this are: 1) the University of Illinois at Urbana-Champaigns College of Engineering annual science fair style open house aimed at showcasing the talent and ingenuity of their engineering students to the public,[6] and 2) the engineering expo at Kansas University. Students, student groups, and faculty across the engineering college participate in these outreach events by way of presenting demos, hosting engineering-themed competitions, tours of facilities, and informational sessions. Although the in-classroom outreach program presented herein is not meant to replace or compete with such elaborate events, it can offer unique advantages to K outreach. For one, the presented in-classroom event may be a great way for a department to incorporate outreach into their program in the absence of a college-wide event similar to the ones mentioned above. Secondly, while the in-classroom event cannot reach as large an audience as a college-wide (or campus-wide) event, it can offer an opportunity for a more intimate interaction between lege-wide event can run the risk of being viewed similar to a spectator sport where the visiting K students are exposed credibly bright engineering students, but are not able to see themselves with the capacity to perform at such level. In a classroom setting, the K visitors are exposed to 1) all types of students and their vulnerabilities, 2) simple projects focused on showcasing engineering aspects of day-to-day life as opposed to the cool and fancy things engineering can make, and 3) a better sense of the engineering classroom. Moreover, the design criteria imposed on the presented in-classroom outreach (see Methods) ensures that K visitors are active participants in the experiments as a way to learn key engineering principles, i.e., a successful ChE design is one that can be carried out by K students in their own classroom. Thirdly, the present in-classroom project-outreach event offers the possibility of tracking impact on participating K students and their eventual college enrollment since recruitment for engineering colleges that do have an on-campus outreach event, the presented outreach approach may serve as a way for departments to involve more of their undergraduatesnot just the high achieverssuch that they have more demos to showcase and can foster a more intimate interaction between the K audience and engineering students. CONCLUSIONS Visual/hands-on demonstrations have long been an effective [7, 8] and the each-one-teach-one approach to knowledge transfer has been proven to enhance students learning experience. Here, we show that these two approaches can be combined to create a unique course project within the chemical engineering cur riculum that allows ChE undergraduate students to enhance their understanding of key course concepts while simultane -Figure 5.

286ously exposing HSS to basic concepts of chemical engineering. unique project presentation/outreach format indicated a better understanding of the demonstrated engineering principles. More importantly, the HS audience (including teachers) indicated an overwhelming interest in chemical engineering as a result of their participation in the ChE course project. Overall, the incorporation of K activities into the chemical engineering course curriculum overcomes the time commitment barrier that often prevents college students and faculty from participating in outreach to K12. Furthermore, this project-out reach class presentation format likely presents engineering to high school students in a less intimidating manner where these students themselves can get involved with demonstrations of engineering principles. This conclusion is evident in the highly positive response of HSS to the survey question focused on their perceived ability to repeat ChE demonstrations in their can serve to demystify the college experience for these visitors. Lastly, while this type of class project-presentation easily lends itself to mass and heat transfer, it can readily be adapted to other chemical engineering courses, including material balance, the hands-on experiment for freshmen in chemical engineer ing developed by Prof. Hohn at Kansas State University[8] can Practical tips for replication are listed in Table 3.

Engineering faculty members often complain that most of their students are Robs and pitifully few are Michelles. Unfortunately, few of us do anything in class to stimulate our students to take a deep approach: we just give them tricky tests to see if they can do more than plug in, and then gripe that theyre apathetic and incompetent when they cant. For tunately, theres something more productive we can do. The following conditions increase the likelihood that students will adopt a deep approach to learning.1Student-perceived relevance of the subject mat ter. Students will not struggle to achieve a deep understanding of material that seems pointless to them, any more than we would. To motivate them to do it, let them know up front what the mate rial has to do with their everyday lives ( e.g. and mass transfer and reaction in the atmosphere and their homes and respiratory and digestive eventually be called on to solve ( e.g., fabricating improved semiconductors, developing alternative energy sources, avoiding future environmental catastrophes). Clearly stated instructional objectives, practice, and feedback. Students are not born knowing how to analyze deeply, and little in their precollege ex perience is likely to have fostered that ability. To get them to pull meaning out of lecture material and solve problems that go beyond those in the text, spell these objectives out and give concrete examples of the kind of reasoning desired. Then explicitly ask the students to carry out deep anal ysis in class activities and on homework and give them constructive feedback on their attempts. Appropriate tests. Provided the preceding condi tions have been met, include questions that call for deep analysis on all tests. If the students know they will only get surface questions (closed-ended exercises that require only standard solution pro cedures), most will likely take a surface approach to learning the material. If they expect some deep questions (more open-ended questions that require greater understanding), most Michelles and Arts and perhaps even some Robs will be motivated to take a deep approach. Choice over learning tasks. Provide bonus problems and/or optional projects and/or alternatives to quizzes and/or optional self-paced study and/or choices between group and individual efforts. Reasonable workload. If students have to spend all their time and energy just keeping up, theyll fall back on a surface approach. The research indicates that by establishing these conditions we may substantially increase the number of our students who think critically about the material we are presenting, try to discover its meaning and its relationship with other mate rial they have previously learned, and routinely question the inferences and conclusions that we present in class. Whether or not well know what to do with these people once we have them is a question for another occasion. All of the Random Thoughts columns are now available on the World Wide Web at


289Over the years, the engineering application of transport phenomena has contributed to research advances in various biomedical and pharmaceutical technologies. Transport processes are important factors in the design and operation of biomedical devices used for sensing, diagnosing, or imaging purposes, as well as applications including drug and gene delivery, biological signal transduction, and tissue chemical engineers have had a major impact, particularly for sites. It has been projected that the demand for drug delivery systems in the United States will expand more than 10% annually to $132 billion in 2012.[1] drug delivery systems extend into all therapeutic classes of pharmaceuticals and encompass a wide range of compounds and formulations. Considerable attention has been devoted to the design and development of drug delivery systems as evidenced by the exponential increase in the number of books, review articles, and research papers published. These drug delivery devices which include: i) reduce systematic toxicity by providing localized delivery; ii) provide precise timing in delivery; iii) protect drugs from in vivo metabolism, thus achieving higher drug stability, longer therapeutic effect, and lower dosing frequency; iv) enhance delivery of poorly soluble drugs; and v) increase in cost-effectiveness. In the development of these drug delivery devices, mathematical modeling of the release process is important since it establishes the mechanism(s) of drug release and provides more general guidelines for the development of other systems.[2] Undeniably, many successful controlled-release drug delivery devices have been developed as a result of an almost arbitrary selection of components, [2] Design Project onCONTROLLED-RELEASE DRUG DELIVERY DEVICES: Implementation, Management, and Learning Experiences QINGXING XU, YOUYUN LIANG, YEN WAH TONG, AND CHI-HWA WANG Qingxing Xu is a Ph.D. student in a joint degree program between the National University of Singapore and the University of Illinois at UrbanaChampaign.

290This paper describes the introduction of a drug delivery project in a mass transfer course. Farrell and Hesketh[3] have riculum and in a senior-level elective. The authors reported an experiment that involved drug release from a lozenge formulation, and the students were required to determine the drug concentration as a function of time, evaluate the drug dissolution rate, and compare between experimental interesting daily-life examples that have been reported by various authors to illustrate the concepts of heat and mass transfer, which include i) processing of ice cream, ii) cooling of a cup of coffee,[5] iii) cooking of potatoes,[6, 7] iv) drying of a bath towel,[8] and v) microwave drying.[9] Mass transfer phenomenon may also be illustrated via simple experiments to determine liquid[10] or vapor[11-13] or via complex equipment to evaluate oxygen transfer in a bioreactor or diffusion across a membrane.[15, 16] The main objective of this drug delivery project is to show how the principles of mass transfer are employed in pharma students to various fabrication techniques of drug delivery devices, before they proceed with vigorous mathematical modeling of these devices of various geometries. Mathematical modeling of drug release provides insights concerning device shape and size on the effect of the release of drug. interest on controlled release in the open-ended component of the project.

Four geometries of the delivery device made of polymer A have been proposed, which include: i) a sphere with a radius of 3 m, ii) a cylindrical tablet with a radius of 3 m and a height of 6 radius of 3 m, and iv) a rectangular cuboid with a length, width, and height of 6, 6, and 7 m, respectively.

From Figure 2, it becomes clear that to satisfy the therapeutic requirement of at least 20% of the drug being released to the body within one week, all four geometries can be used. The geometry that has the closest percentage release of 20% tablet have the highest specific surface area, followed by the cuboid and then the surface area, thus resulting in almost the same percentage of drug being released to the body during the initial release stage. In the next part of the question, given the released to the body within one week, we to rewrite the expression for the drug release equation explicitly to solve for the diffusion used to determine the unknown. It is found 3.11 10-16 cm2/s. The drug concentration at the center of the device is close to the initial drug concentration of 30 mg/cm3.PROJECT PHASESFor the heat and mass transfer course, a total of three hours of formal lecture and one hour of tutorial class had been allocated per week over 13 teaching weeks (with a recess break during week 7). For the project component, four contact sessions of one hour each were scheduled regularly during the entire phase of the project (12 weeks). The students were organized into teams of six, with two students in each team appointed as the chairperson and vice-chairperson, respectively. The following paragraphs contain more details about the activities planned for the students. The project can be roughly divided into two main phases. It should be noted that some of the tasks had to be carried out simultaneously in order to achieve proper progress. Figure 1.

Based on dimensions of the geometries described in problem statement, the specic surface areas for the sphere, cylindrical tablet, cuboid, and cylindrical ber are 1, 1, 0.952, and 0.667 m-1, respectively. The corresponding percentages of drug released after 1 week are 38.8, 38.1, 36.2, and 27.5%, respectively.


294Phase One (Week 1 Through Week 9) during week 1 was to provide an interesting, enjoyable, and challenging overview of the numerous techniques for the fabrication of microand nano-particles to the students. In addition, the students were advised to view a laboratory-made video that was readily available for download from the course website. The video showcased actual experimental setups and explained principles of some of the fabrication techniques techniques for the large body of students, it was hoped that the video would help them understand how the particles were fabricated in the laboratory. The teams then spent the remaining seven weeks conducting a detailed literature review on a particular fabrication of the project. In the sessions, the teams shared their literature the grading of the mid-term reports. Phase Two (Week 5 Through Week 12) For the second phase, attention was focused on the second and third sections of the project. Due to the curriculum structure of the course, the topic of mass transfer was covered only during the later part of the semester. Thus, an introduction of the topic to the students was essential for their project work. The second contact session scheduled during week 5 was to introduce the concept of mass transfer and focus on the physics of diffusion. graduate course. The third contact session scheduled during commands and syntaxes that would be used frequently in their projects. Much of the time was focused on the introcylindrical geometries. of week 5, mainly to provide technical assistance for the conducted on week 5 and from week 8 through week 12. Apart further meetings or follow-up meetings with the student facilitators whenever necessary. When the project phase reached week 12, there had been troubleshooting. These questions scheduled during week 12. This was done so that the rest of the ROLES OF MANAGERS AND STUDENT FACILITATORSThe project was administered by two managers and two student facilitators. The managers were the course lectur ers and their main roles were to oversee the overall project management, supervise the teams, and advise the student and introduced various techniques for the fabrication of microand nano-particles. They were also in charge of maintaining the course website. In particular, the website was updated regularly with important project announcements, essential contact session materials, relevant project references, and most importantly an up-to-date compilation of frequently asked questions based on the e-mail enquiries sent by various teams. The compilation of the frequently asked questions which include: i) to ensure the information was available and communicated to every team, ii) to allow the teams to learn based on the problems or questions raised by others, and iii) to lighten the e-mail load of the management team by minimizing the need to answer similar questions raised by different teams. Small sharing sessions were also led by the managers, together with the student facilitators, after the teams had submitted their mid-term reports. Those teams that focused on the same area of fabrication technique were grouped in the same sharing session. In each session, the teams shared fabrication techniques. In addition, the student facilitators provided feedback on the grading of the mid-term reports. In doing so, a two-way exchange of knowledge between the students and the management team was possible. The main role of the student facilitators was to conduct the remaining three contact sessions with the relevant teaching materials needed for the project. Moreover, they had expertise programming and were able to provide technical were also handled by the student facilitators. At the end of the the managers and student facilitators participated in grading the PROJECT ASSESSMENTThe project constituted 20% of the overall assessment of the course, with the rest composed of assignments, quizzes, and literature, reports were graded based on the comprehensiveness of the review, the ability to integrate information from multiple sources, and the validity of the various points raised.


295For the second section, the reports were graded based on the ability to explain the methodology and justify the assumptions and the choice of equations, the accuracy of the solutions, and the discussion of the simulation results. A good discussion should include explanations for the differences in drug graded based on the innovative linkage or coupling of the earlier two sections of the project and the ability to justify those claims. In one particular report, the team recommended a particular fabrication technique for the encapsulation of the assigned drug, with the consideration of factors such as: i) the operating conditions of the fabrication process (e.g., temperature and pH); ii) the properties of the drug (e.g., solubility, hydrophobicity, and stability); and iii) the typical drug-release rates and thus, the therapeutic window of the target drug. The selection of an appropriate fabrication technique was important since some of the conditions would sometimes result in the loss of biological activity of the drug being encapsulated. In another report, the team used the skills gained from the second section of the project to model several experimental results based on the assigned drug and the selected fabrication technique from the the encapsulated drug. The two projects listed here are some of the best reports and serve as outstanding examples.OUTCOMES/RESULTSMost of the teams were capable of providing detailed discussions and integrating information from multiple sources for their literature reviews. It was commendable as the students were only in their second undergraduate year and did not have prior experience in the research area. For the design calcula tions, many teams found them to be particularly challenging codes. Although the students had prior experience in MAT programming, the translation of a descriptive problem code was not a skill in of the common errors made included the use of wrong equaseries to reach convergence. In addition, a few teams could for the cylindrical geometries. component, correct trends in the drug concentrathat, a handful of teams had written codes that were capable of generating the required This certainly indicates that the conconsultations, and the compilation of frequently asked questions have proven to be effective in guiding the teams in their project work. The third section of the project turned out to be the weakest component among the teams. As it was an open-ended component, the qualamong the various teams. There were some outstanding teams that were able to model experimental data by using published diffusion in Figure 3. While many of the teams provided innovative linkage or coupling of the knowledge gained from Figure 3. Comparison between experimental and theoretical release proles of dexamethasone from nanoparticles.[25] The proles are obtained based on a diffusion coefcient of 22.6, 4.8, 12.7, and 4.8 10-18 cm2/s for PTMC salting out, mPEG-PTMC salting out, PTMC single emulsion and mPEG-PTMC single emulsion, respectively. The corresponding average sizes of the nanoparticles used are 186, 95, 261, and 103 nm, respectively. The experimental drug release data for week 1, 2, 3, and 4 are estimated based on the published gure in the reference.


296the earlier two sections of the project, a handful of teams had simply discussed the fabrication techniques without consider ing the drugs they had been assigned. An online survey was conducted at the end of the course to gather project feedback and suggestions. Out of a in this voluntary survey and the results Most of the students perceived the design the project description. Upon completion of the project, more students felt that the ponents required in this project, more than 50% of the students found those that programming to be the most challenging (Figure 5). Not surprisingly, they also found contact sesprogramming was illustrated, to be the most useful resource (Figure 6).CHALLENGES/LESSONS LEARNEDThe main challenge of the project is that the students do not have prior knowledge about drug decomprising a wide range of literature. Thus, it is essential to draw a proper framework for the scope of the project, simulate interest among students, and illustrate the importance of mass transfer in these drug delivery devices. Additionally, it is important for students to understand the various fabrication techniques of drug delivery devices before they embark on reviewing related literature materials. Due to the limitation of time and resources in the course, however, students are not able to get hands-on experiences with various fabrication techniques. One possible area for improvement is to conduct a laboratory tour where various fabrication techniques will be demonstrated on the spot. This will be complementary to the existing laboratory courses since these fabrication techniques are not currently covered. Many of the students lacked the skills in translating a code. Deciding on the amount of help to render the teams be provided so that the teams would be able to start working on the project. On the other hand, too much guidance would be tantamount to spoon-feeding and would deprive the teams of a chance to learn from their mistakes. To overcome this situation, simple examples can be used as teaching materials Figure 4.

The open-ended component of the project was intended to allow room for creativity in responses from the various teams. about what type of areas to focus on were asked by many teams. In addition, the teams did not know the percentage of credit for the three sections of the project and thus, they were unsure of the amount of effort required for individual sections. The problem can be circumvented by informing teams upfront of the weightage of the individual components.CONCLUSIONIn the course of this project, the students have been assessed on the current techniques for the fabrication of drug delivery devices and the design of these delivery devices using MAT being implemented, there are many areas that can be further improved. This particular project can potentially serve as an interesting model for other mass transfer courses.ACKNOWLEDGMENTS

299A mathematical model is an abstraction of a physical system, i.e., a mathematical image of the reality. These models are of great importance in engineering because they can provide relevant information about the system being modeled which may not be available from experiments, e.g., a model can explain variations in the measurable macroscopic properties of a physical system using accurate information from the microscopic level, which cannot usually be measured in a laboratory. Also, mathematical models help engineers to make decisions and to improve the quality of a process. On the other hand, mathematical models can lead to wrong deci sions or conclusions about the system under study if they are not validated with experimental work. Therefore, a complete study of a physical system should integrate modeling, simulation, and experimental work. The process modeling fundamentals are usually introduced to engineering students in one or two courses on transport of transport phenomena,[1-5] most of them present the momentum, energy, and mass transport phenomena as independent subjects. This limits the application of the concepts learned in transport phenomena courses to practical systems where different laws of physics may occur simultaneously, e.g., the an asymmetric geometry. It has been widely recognized that framework constitutes one of the keystones in fundamental engineering sciences and contributes to the development of ogy.[1,6] Therefore, it is important to expose undergraduate engineering students to the modeling and simulation of physical processes that involve the study of two or more laws of physics; this has been referred to as multiphysics modeling.

300The multiphysics modeling of a physical process may involve not only the simultaneous solution of different laws of physics occurring at the same time but also the coupling of two or more phenomena occurring at different length or time scales. The latter class of systems, also referred to as multiscale systems, are of increasing interest in engineering since they can be used to describe the macroscopic properties of a physical system by modeling and simulating the microscopic behavior of the physical process.[7,8] Although a sound background in numerical techniques may be desirable for simulating the type of processes previously described, the use of commercial software may prove very valuable for accomplishing this task, especially for those who are just becoming familiar with the subject of modeling and simulation. In the Fall of 2008, the Micro and Nano Systems Computer-Aided Design (CAD) course, NE-336, was offered for undergraduate program at the University of Waterloo. The goal of this course is to study the process modeling fundamentals and to train students in the modeling and simulation technology. Also, the students are exposed to conventional numerical techniques available for solving both ordinary and partial differential equations (ODEs and PDEs, respectively). Since the course deals with the modeling and simulation of micro and nano systems, one of the most important goals of the course is to train students in the implementation of multiphysics models. For this purpose, they have to perform different computational laboratories that provide them with practical hands-on experience in the simulation of micro systems. These laboratories are intended to provide a clear physical understanding of the systems being simulated. Since the course is mainly focused on the modeling and numerical simulation of multiphysics systems, only introductions to the electronic and atomistic simulations required to model nano systems are discussed by the instructor in the last section of the course (see course structure in section 2.1). The goal of this paper is to give a general overview of the NE-336 course and to present one of the computational laboratories covered in the course. The laboratory presented in this work corresponds to a drug delivery system where the macroscopic properties of the system depend upon the variations at the microscopic system level. The rest of this paper is organized as follows: in section 2, an overview of the NE-336 course is presented. Section 3 presents a computational laboratory that addresses the release of a drug in a storage tank. The mathematical model used to describe the behavior of this system, the challenges posed by this problem, and the laboratory tasks performed by the presents the evaluation made by the students regarding the learning experience in this course. Concluding remarks are presented in section 5. 2. COURSE DESCRIPTION Micro and Nano Systems Computer-Aided Design is one of the core courses in the Nanotechnology Engineering cur riculum at the University of Waterloo. This course, NE336, is composed of three weekly hours of lecture, one weekly hour of tutorial, and three biweekly hours of computational laboratory. Lectures are used by the course instructor to provide the essential course material. Tutorial sessions are used to reinforce the concepts presented in the lectures, to solve sample problems, and as a pre-laboratory session. Laboratory sessions are used to help students to gain practical experi ence in the implementation of multiphysics models in an application software, on its simulation, and on the analysis of the simulation results. The course grading is based upon a midterm exam, laboratory reports and assignments, handcovers the complete course content. The course is suitable for those students who are already familiar with classical thermodynamics and the traditional analytical methods for solving ODEs and PDEs. The course objectives can be summarized as follows: mass transfer. solve ODEs and PDEs. used commercial software based in Finite Element light the complexity of the solutions of multiphysics tween different mathematical models is implemented. 2.1 Course Structure course content has been divided as follows: principle modeling and empirical modeling. Here, the basic concepts used to model physical systems that follow the laws of classical mechanics (i.e., conservasimple physical systems. The basic steps in the modeling process, the different approaches used to obtain a to perform empirical modeling are discussed. Each of the above topics is supported with practical examples, e.g. circular tube. The books by Bird, et al., and Tosun are the basic sources for this section of the course. This section presents the traditional numerical


301methods available to solve initial value problems, such as Euler and Runge-Kutta methods, boundary value problems, the shooting method, and eigen-value problems for solving ODEs. Similarly, methods used in element method, are discussed. In this section of the course, a detailed discussion on truncation and discretization errors in numerical analysis is presented. For example, students are made aware of the errors gener ated by the use of approximate functions in the different terms of the PDEs containing the variable to be solved. Here, it is also shown that the errors depend on several factors, such as the truncation of Taylor series to form e.g. second order, the order of a Lagrange polynomial to size of the mesh elements. Also, comparisons between ence methods, i.e., forward, backward, and centered methods for regular and irregular geometries are also discussed on this part of the course. Furthermore, a grid convergence analysis is evalu ated by solving a particular system using different grid sizes. From this analysis, the students realize that meshing the domain of the physical system is a key step in the numerical set-up of the problem that has a direct effect on the numerical solution. A formal grid convergence analysis that involves the use of relatively complex and time-consuming algorithms to deal with stiff multiphysics systems is beyond the scope of this undergraduate course. The basic references for this part of the course are Chapra and Canale and Chadrupatla and Belegundu. The goal of this section is to expose students to physical sys tems that can be modeled using two or more laws of in the implementation of such models in the appli cation package used in the course, i.e., COMSOL. The examples provided in this section span from the modeling of the Joule heating effect in a section of a pipeline to the modeling of the mass transport of an inillustrative examples are used by the course instruc tor to show the importance of sensitivity analysis and the effect of parameter uncertainty on the simulation results. Most of the topics presented in this section are taken from Zimmerman, Bird, et al., Tosun, and the COMSOL library. The last part of the course is used to model physical systems where the coupling between the different mathemati cal equations appears at one boundary condition, i.e., extended multiphysics systems. Also, the implementa tion of multiphysics models with periodic boundary conditions is discussed. Likewise, this last section of the course is used to introduce the students to the traditional methods used in the modeling of systems at the atomistic, molecular, and coarse-grained level. This section of the course is supported with the COM SOL library, Zimmerman, and Hung, et al.2.2 Computational Laboratories The computational laboratories are a key component of the NE-336 course. In the laboratory sessions, the students are packages is primarily used to solve those systems that can be modeled using ODEs, whereas the second one is used to model physical systems that involve PDEs or a combination or PDEs with ODEs (see case study in Section 3). students with an overview of the laboratories to be performed throughout the course. During this session, the course instruc tor implements, simulates, and analyzes two simple models on each application package. The model implemented in tank process modeled using two ODEs, whereas the model implemented in COMSOL describes the unsteady Joule heating effect of a micro-resistor beam. The learning goals of the to both of the application packages used in the course. In the ratory they learn the basic steps in the modeling process in COMSOL. For these laboratories, the physics of the models implemented on each application package are relatively simple. The third laboratory addresses the implementation of a drug delivery model in COMSOL, which is presented in electro-migration model and a micro cantilever beam model, respectively. These models require the application of differ ent laws of physics that make the problem challenging to the students. The last laboratory session of the term, a laboratory quiz, is used to evaluate the students in their ability to imple ment models in both application packages. This quiz is of great skills learned by the students in the laboratory sessions. Each of the laboratory manuals is divided in three sections: Section 1 contains a brief introduction of the physical system implementation in the corresponding application package. Section 2 covers basic questions regarding the implementation of the model. Section 3 lists questions that require additional simulations of the model, model analysis and parametric sensitivity analysis. The students must submit at the end of the laboratory session their responses to Section 2. This portion of the laboratory is used to evaluate the students performance on the laboratory. Section 3 of the laboratory manual is sub-


302mitted by the students a week after the laboratory session is completed. This is because the questions posed on this section require an in-depth analysis of the model and additional computational simulations. This portion of the laboratory (Section 3) is considered as an assignment for the course. 3. CASE STUDY: DRUG RELEASE IN A BATCH PROCESS This computational laboratory deals with the transient release of a drug in a mixing storage tank. The learning objective of this computational experiment is to show the students the modeling and simulation of a system described by an ODE coupled with a PDE at one of the boundary conditions. This kind of mathematical modeling, also referred to as extended multiphysics problems, is very common in chemical processes where the multiple scale modeling of the physical phenomena occurs.[6] The physical description of the process is shown in to study the drug release kinetics in biological systems (Tan, et al.[12,13]). The drug is placed into a drug reservoir, assumed to be a solid sphere of radius which is encapsulated by a polymer substance, e.g., a nano-gel. The encapsulating layer is used to control the drug delivery rate. As shown in Figure 1, the nano-particle, i.e., the nano-gel and the drug reservoir, are assumed to form a solid sphere of radius R. A mixing nano-particles, Np. The tank is used to mimic the drug cone.g., a human body. The system is assumed to be isothermal and well stirred. Also, the i.e. considered to be constant. Due to the educational nature of the present laboratory, severations that can be involved when dealing with the modeling of a drug delivery system. The drug particles are considered to be appropriately described by an average particle behavior regarding their mass transport properties. That is, classical continuum transport equations are assumed to apply to the presented drug delivery system, which is composed of both atomistic dynamic simulations may be required to model the dynamic behavior of each particle in the system. These simulations, however, may be lengthy and may increase the complexity of the present educational laboratory. Since the objective of this computational laboratory is to present the modeling and simulation of an extended multiphysics system such as the drug release problem, molecular simulations of the drug particles are outside the scope of the present laboratory. Moreover, in a more realistic scenario the drug reservoir may consist of a polymeric matrix that can experience swelling and erosion. Further, a constant drug release rate may be sought if the solution inside the drug reservoir is oversaturated (since the maximum concentration of drug should be constant and correspond to the saturation concentration). The transport of the drug through the drug reservoir and the polymeric material is controlled by the unsteady diffusion within the sphere. This diffusion process is mathematically described as follows (microscopic model): where CA is the drug concentration in the nano-particle (mol/m3); r, the radius of the solid sphere (m); and D is the diffusion 2/s) in either layer one (Dr) or layer two (Dp). assumed for this microscopic process are as follows: Ai.e., A = CA0where the term kc is the drug concentration on the surface of the sphere on the Figure 1. Physical system. Figure 2. Coupling of the macro and the nano systems.


303 is the concentration of the drug in the tank, i.e. a point in the tank that is assumed to be far away from the surface of the particle; and CA0 is the initial drug concentration in the drug reservoir. Figure 2 shows the interface between the surface of the lationship must be given to relate the interfacial compositions and One alternative is to assume equilibrium across the interface, that is, where K represents an equilibrium constant. The unsteady (macroscopic model): where V is the tanks volume (m3) and Ap is surface area of the particles (m2). The initial concentration of the drug in the tank is assumed to be zero. The present educational laboratory presents the students with the challenge of coupling the drug transport in the nano-particle and its distribution in the storage tank. This is because the drug concentration in the bulk depends on the drugs concentration at the surface of the nano-particle. Thus, the students must solve a PDE [Eq. (1)] and an ODE [Eq. (3)] simultaneously. Since the coupling between the drug transport in the nano-particle and the concentration of the drug in the study is considered to be an extended multiphysics problem.[16] The solution of this system of equations [Eqs. (1) and (3)] requires the implementation of numerical techniques. Thus, this type of problem is suitable to exemplify the capabilities of COMSOL in solving practical engineering problems. The proposed model is built-up in COMSOL in two sequential steps. First, only the drugs transport in the nano-particle is modeled according to Eq. (1) without considering the coupling of this equation with Eq. (3), i.e., is assumed to be negligible [ =0 in Eq. (3)]. For this laboratory, the students use the 2-D unsteady mass transport by diffusion module in COMSOL[11] to account for the transient behavior of the drug concentration throughout the nano-particle, described by Eq. (1). It is important to mention that Eq. (1) can also be implemented using a 1-D model given the symmetry of the sphere. In this laboratory, however, the choice of using a 2-D model is made because the step-up of this type of model is simpler than the one corresponding to a 1-D model, especially given the two different materials of which the nano-particle is composed. Also, when implementing a 2-D model, the varia tion of the drug concentration can be obtained for a complete cross section of the sphere, giving a clear physical meaning of the variation of the drug concentration in the sphere at of the radius of the nano-particle for different times ranging drug inside the drugs reservoir and the other corresponds to the diffusion of the drug through the nano-gel. From this plot, the students can observe that different nano-gel and drugs reservoir materials will have an effect on the drugs diffusion rate. Thus, in the actual computational laboratory, the students are requested to test this model using different drugs reservoirs and nano-gel materials. Once the nano-particle model has been implemented, the second step in the modeling process consists of coupling the diffusion model with the variations of the drug in the storage tank described by Eq. (3) (macroscopic model). The 1-D [11] was used to represent the macroscopic ODE model. Thus, a single line of arbitrary length is used to represent the variation of the drug concentration in the storage tank [Eq. (3)]. Since the Figure 3. Concentration prole in the nano-particle, CA, for different times from 600 1000 s.


304coupling between the microscopic model [Eq. (1)] and the macroscopic model [Eq. (3)] occurs at one boundary condition intersect with the external surface of the nano-particle, i.e., at r=R. Then, the variable that represents the drug concentration at the surface on the nano-particle side is made available in the 1-D macroscopic model using the variable extrusion option in COMSOL.[11] This is the most challenging part in the implementation of this model in COMSOL. The laboratory manual includes hints in this section to assist the students with the coupling of the microscopic and the macroscopic model. Also, the students can seek help from the laboratory assistants. Once the drug-release model has been completely implemented, the students are requested to simulate this process under different scenarios. The base case scenario assumes that the concentration of the drug at the radius of particle sides, i.e. evolution of the drug concentration in the storage tank for this scenario. At the end of the laboratory session the students scenarios considered in the laboratory were designed to provide an in-depth knowledge of the drug delivery process. This includes a parametric analysis on the effect of using different materials for the encapsulating layer and a study on the effect of the thickness of the nano-gel layer on the drugs delivery rate. Since these tasks require an in-depth analysis, they are submitted one week after the laboratory was performed and are considered as assignments in the course. 4. ASSESSMENT AND FEEDBACK At the end of the term, a survey designed by the Faculty of Engineering of the University of Waterloo was conducted with students who were enrolled in the NE-336 course. The objective of the survey is to provide instructors with feedback as to how the teaching methods and skills were received by the students. From the responses of the survey, there was a clear consensus that the new skills learned in this course will be relevant to the future careers of the students and that the course introduced them to a new aspect of engineering: modeling and simulation. Also, the students could immedi ately realize how the recently acquired knowledge could be applied to their careers as engineers. A follow-up on a few of the students who were enrolled in this course indicated that some of them are currently applying the skills and subjects learned in this course to perform their fourth-year projects and in their co-operative terms (work internships). Although students expressed appreciation of the hands-on experience provided by the computational laboratories, some of them also considered that the laboratory tasks were lengthy. This aspect coincides with the evaluation of the course where the required course workload was unfavorably evaluated by the students, in contrast with a very positive evaluation of the assignment contribution. Some students also expressed that more time could be spent in class explaining the systems to be simulated in the computational laboratories. These valuable comments from the students have been taken into consider ation to improve the design and the learning experience for nanotechnology students who will take this course in the future. Some relevant comments expressed by the students in the survey are the following: Student 1: I think the best aspect of the course content was the numerical the mathematical foundation for doing any computational mathematics. Student 2: I think this was a vital course to have in undergraduate education, especially in engineering or applied science. Most of the mathematics tackled by us are not analytical, but numerical. This course provides the toolkit to approach such applied math problems.5. CONCLUDING REMARKS A general overview on the modeling and simulation course offered in the nanotechnology engineering undergraduate program at the University of Waterloo was presented. The aim of this course is to make nanotechnology engineering Figure 4. Time-dependent prole of the drug concentration in the tank,


305students familiar with the modeling and simulation of physical systems that involve the multiphysics nature of most of the processes relevant in engineering. To achieve this task, students must complete a series of computational laboratories that cover the implementation of multiphysics models in a suitable educational software package such as COMSOL. A computational laboratory that addresses the implementation of a relatively simple drug-release model was presented. The goal of this laboratory is to train the students in the implementation of extended multiphysics systems and to show that the microscopic behavior of a process has a direct effect on the macroscopic measurable properties of the system. Many of the students who took this course in Fall 2008 are currently applying the tools learned in the course in their fourth-year plished and that the modeling and simulation of multiphysics systems is an essential component in the curriculum of the nanotechnology engineering students.

306Although teaching is a critical mission of any college or university, the heightened research aspirations of many institutions necessitate that faculty members spend less time on instructional activities, at least if that new professor wants to exceed the research standards set for tenure and promotion. Thus, when a faculty member is tasked with teaching a new course, developing a good set of instructional materials can be a challenging, time-consuming task. In this paper we review some of what we consider the best practices in engineering education applied to the following courses: solution thermodynamics; heat and mass transfer; kinetics and reactor design; process control; and senior design.

307 SOLUTION THERMODYNAMICS This course, also commonly called Thermodynamics 2, focuses on mixtures and mixture phase equilibrium as well as this course normally consists of exclusively chemical engineering students. Note that since this is typically the second part of a two-part Thermodynamics sequence, some of the course in our previous work[3-6] are applicable to the Solution Thermodynamics course. Best Practices / New Ideas There are certain phenomena within this course that, although working against intuition, can be visualized through experimentation (both desktop and simulation). For example, consider the following straightforward demonstrations that can be performed to show mixture effects: Heat of solution thermocouple placed in the solution, have the students attempt to estimate the heat of solution. Excess volume ml of ethanol with 500 ml of water. The resulting solution is ~970 ml, which demonstrates that liquid volumes are not additive. Miscibility Additionally, since changes in molecular-level interactions can manifest themselves in complicated phase behavior, simulation can be utilized to demonstrate these effects in a powerful way. One source for this information is the website for the Etomica environment created by Kofke, which houses many applets, some of which focus on fundamental behavior germane to an undergraduate solution thermodynamics course.[9]Other recent ideas used to best teach the concepts of this course include: liers Principle. emphasizes uncommon intuition and focuses on the Mathcad. classroom response systems to allow immediate feedback from students for formal or informal assessment. ing liquid-liquid phase equilibrium and the potential for false solutions; for example, when the initial guess for the iterative method is too far from the actual solution, it is possible to converge to a local and not a global mini mum. thermodynamic properties using both equations of state and Gibbs excess energy models. state in calculating mixture phase diagrams and chemical modeling approaches to introduce gas-liquid solubility. non-ideality, including hydrogen bonding, to solubility and volatility in both a qualitative and quantitative manner. It is also noted that thermodynamics is a subject area not just encountered in chemical engineering, but in mechani cal engineering, chemistry, physics, and other disciplines. Accordingly, educational ideas from those disciplines exist related to thermodynamics, and the interested reader might well want to consider insights and ideas from faculty outside of chemical engineering. For example, the Journal of Chemical Education (published by the American Chemical Society) contains many educational articles related to thermodynamics, such as recent contributions on an experimental technique [19] and a laboratory procedure for gas clathrate hydrates.[20] The Physics Teacher discusses various fundamental thermodynamics concepts as well as some interesting analyses, such as the thermodynamics of a thermos.[21] Articles on the design of a bench-top, portable refrigeration apparatus for use in a classroom setting can be found in the International Journal of Mechanical Engineering Education.[22] Also, Computer Applications in Engineering Education publishes articles related to thermodynamics education, such as a recent contribution on the creation of residue and Mathematica.[23] Finally, one can utilize this class (or the previous Ther modynamics class) to provide an opportunity for students to design, estimate costs, build, and implement a project related to course concepts. In such an exercise, students are expected to keep track of their budget, set milestones, take notes to record their successes and failures, and prepare a detailed report. Industrial visitors may be interested in attending and projects in the following year can be used to improve upon the existing design. Some example projects have demonstrated ethanol distillation through building a still and the appearance propylene glycol n-propyl ether system. Trouble Spots Trouble spots for this course include: and lose the big picture. Phase equilibrium calculations plicated, and there is a tendency to work towards arriving at an answer with little appreciation or interpretation of the result. Depending on the situation, the use of an Excel add-in such as XSEOS or a web applet to determine phase equilibrium from an equation of state may be more appropriate.

Best Practices / New Ideas Recent advances in simulation and modeling allow for a marked change in how heat and mass transfer can be taught in the classroom. There are several examples published in the [29-31] numeri cal solutions,[32, 33] similarity solutions, molecular simula tions,[9,35, 36] and desktop modules.[37] describes the use of Fluent software in the dynamics, the teaching principles illustrated in this paper can be extrapolated to heat and mass transfer courses. utilizes the PDE toolbox feature in Matlab transfer, and solid mechanics. employ COMSOL Multiphysics to illus and mass transfer, and reaction kinetics can be extended to fuel cell applications. solves free convection problems using similarity variables and a numerical simulation of an initial value problem. uses Mathematica to solve membrane permeation problems using the complete mixing model (alge applies similarity methods to three clasrectangular channel with isothermal walls. illustrate the use of molecular-level simulations to predict gas diffusivities. demonstrates ways to use desktop-sized modules to reinforce fundamental heat transfer concepts, including 1-dimensional heat conduction, the effect of contact resistance, steady-state and transient heat gen eration, and convection.

KINETICS AND REACTOR DESIGN Kinetics, catalysis, and reactor design distinguish chemical enBest Practices / New Ideas Like other subject areas, simulation and modeling are used in kinetics and reactor design. There are several examples published in the recent educational literature that will now be summarized. : Martinez-Urreaga, et al., use MATLAB to simulate the reversible reaction A B, while Fan, et al., simulate the thermal death kinetics of a cell population. : Lawrence, et al., use CFX commercial software to incorporate non-ideal reactors into the curriculum. They develop residence time distributions in tubular reactors and use them to determine conversion for a reaction using Langmuir-Hinshelwood kinetics.

A paper by Muske and Myers[65] integrates principles of statistics and experimental design into a project to determine the forward and reverse reaction kinetic rate constants for ethylene hydrolysis into ethanol. Complicating the problem is that students need to determine the Arrhenius parameters for these reactions. Students are given a budget and request experimental runs from which they are supplied data by e-mail one day after their request. A process simulation with statistiexperimental study. They must decide when they have enough data (or when they run out of money), and possibly adjust their experimental plan in order to perform the analysis.


310The Safety and Chemical Engineering Education (SACHE) program is a joint effort between the American Institute of Chemical Engineers Center for Chemical Process Safety and academic institutions. Founded in 1992, the committee typically organizes a yearly workshop to educate chemical engineering faculty on the importance of safety education. Their website[66] features problem sets and web modules that can be used in the classroom. It is noted that some features of the site require a password for access. An example module is the Chemical Reactivity Hazards Instructional Module[67] developed by Robert Johnson of Unwin Co. The module can be used to motivate the importance of safety in kinetics and reaction engineering. It highlights several major incidents where uncontrolled chemical reactions can result in devastating consequences. Additional safety material is available in Crowl and Louvars textbook.[68] Other resources that could be used in a kinetics course include: table that contains puzzles, quizzes, and a molar mass calculator. The same group has a JAVA kinetics plotter ics to supplied experimental data. to simulate molecular motion, collision, and reaction. The user enters initial concentration of red, yellow, green, and blue molecules. Upon the interaction of a red and yellow molecule, green and blue molecules are formed. The reaction is reversible, and the user can enter the forward and reverse reaction rate constants. Laboratory experiments in kinetics and reactor design include: describe an experiment to explore the heterogeneous reaction of propane in an automobile catalytic converter. The students measure the compounds exiting the converter using Fourier transform infrared experimental data to determine reaction rate parameters. present a batch fermentation experi ment to produce l-lysine in the senior laboratory.

Efforts are also made to introduce non-ideal reactor models, and the advantages and disadvantages of using these models are also stressed.


311PROCESS CONTROL This course tends to stand alone in the chemical engineer ing curriculum, seeming to students (and some instructors) somehow disconnected from other upper-level chemical engineering courses. Coverage normally includes mathematical modeling and dynamic simulation, Laplace transforms and transfer functions, linear dynamic responses for various inputs, controllers, instrumentation and valves, closed-loop analysis, stability analysis, controller tuning, frequency response, and advanced control strategies. Best Practices / New Ideas Of all the courses in the chemical engineering curriculum, this one may have the most variability in how it is taught. Prior to discussing teaching methods, various approaches to course content will be discussed. A recent article published by the International Society of Automation magazine InTech reported on the views of prominent chemical engineers regarding the role of process control instruction.[77] tion, and provide a practical skill set... including enough theory to excite those destined for graduate study. states, We teach fundamental principles, but include only theory relevant to engineering practice, and Focus on basic regulatory control, and do it well. Leave optimization, model predictive control, etc., to subsequent courses and advanced-degree programs. Process Control of theory vs. practice in engineering education. The key to this problem is to provide control courses that provide basic industrially relevant skills while also providing a fundamental understanding of process control and process dynamics. Riggs also states[77] that the course should teach students to: gral, and derivative control action; the concept of stability; and the difference between linear and nonlinear systems. basic control design decisions. There is continuing debate over whether or not to use the La place domain, or to remain in the time domain. Furthermore, the utility of frequency response methods often results in similar debates among members of academia and industry. Tom Edgar (University of Texas at Austin and co-author of the textbook Process Dynamics and Control) suggests[81]: transforms. ler tuning. real engineering problems. A thorough discussion by authors of several process control textbooks about what to teach in process control was recently published.[82] Once the decision of what to teach has been made by your program, preferably in conjunction with feedback from the employers of your graduates, the task of choosing how to teach the course begins. There seems to be general agreement that a combination of experiment and simulation will help students move from theory to application. In some cases, it may make more sense to move from application to general theory. If this inductive approach is taken, some suggestions can be found in the literature: describe the use of small modular kits and Control Station. uses unit operations laboratory-scale apdemonstrates simulation and remote experi ments on batch distillation. Additional laboratory ideas include: describe a nonlinear, MIMO salt-mixing process control laboratory experiment. demonstrate the use of multivariable control for a quadruple-tank process control experiment. suggest experiments on air-pressure tank systems. uses a simple tank in a process control laboratory. Web resources include: hosts a web page including numerous resources for teaching controls. has a number of remote laboratories available online. Software resources include: a modeling interface that uses the same block notation used in most texts Trouble Spots Trouble spots for this course can include: may not have been covered much in prior courses, so a detailed review of a relevant problem like a step response for heated tanks in series may be appropriate. variable s. Despite faculty efforts, this concept will likely remain a mystery to most students. Instead, focus on how conservation laws in the Laplace domain can be arranged to yield key information about process behaviors through parameters such as gains and time constants.


312 must understand the how and why before actively developing models with software like Simulink. The appropriate time to introduce them will depend on your curriculum, but probably should be after students have mastered modeling fundamentals and can at least handle simple Laplace domain solutions for openand closed-loop systems by hand. Some simulation tools, like Loop-Pro, can be used for inductive instruction on principles of control without ways be obtainedat a cost. Students must continually be reminded that there is always an optimal level of control, dependent on the cost to implement control vs. marginal and environmental protection should also be considered. Author Experiences At the University of Kentucky, the emphasis of recent changes in the course has been to bring inductive laboratory and simulation experiences into the course. brings students down to the lab to observe principles of process that serves as a foundation for discussions of principles of process control. Other approaches adopted include: ule on modeling and Laplace transformation.

Students work across multiple courses (including teams at another institution to perform a detailed design of a control system. SENIOR DESIGN The senior or capstone design course can be intimidating to some faculty. In many departments the course was tradi tionally taught by a retired industrial practitioner who had a good idea of the types of deliverables that were representative of what students would encounter in the workplace, but this may not be the case today. In addition, the advent of process simulators in the 1970s and 1980s has had a huge impact on the way that senior design is taught. The senior design course typically includes both traditional lecture content as well as a sheet synthesis and development, process simulation, process economics, and equipment design/heuristics. Depending on the background of the instructor and whether the course is one or two semesters, a laundry list of additional topics might include sustainability and green design concepts,[99] process safety,[100] [101] optimization,[102] selecting materials of construction, readsynthesis, environmental regulations, engineering ethics, batch scheduling, and product design.[103] Senior design is also the last opportunity to reinforce soft skills such as teamwork and communication.[106, 107] Furthermore, the AIChE Centennial Conference has a session on design featuring many of the design textbook authors. Videos of these talks are available online.[7] Best Practices/New Ideas impact how the course is organized, the content that can be covered, and the scope of the design project. According to a recent survey conducted by John Wiley based on a response from 50 departments, U.S. chemical engineering departments are split down the middlehalf teach one design course, and half teach a two-semester design sequence.[108]Instructors have several challenges related to the structure and organization of the course: selective and choose which content is most important for their graduates. Design projects for a one-semester offer ing might be best structured as multiple smaller problems that reinforce the course content being covered. Departto cover additional specialized content, present information on product design as well as process design, invite guest speakers, and pose design projects that stretch over an entire year. lenge for instructors. Starting early is important since mentors. In addition to gleaning ideas from the literature of the spring semester or in the summer to generate some ideas. Contact enrolled students early in the summer and constraints on what the project should include. If your campus has an Engineering Entrepreneurship class, 110] partner with them to include your students. near industry or research organizations, can serve as sources of design projects and mentors. The local AIChE section could be a good resource for local practitioners who would be willing to participate. Industrial alumni


313who have been through the course can be excellent mentors because they are familiar with the deliverables required. In addition, industrial advisory boards may be helpful in identifying key skills expected for new employ on the class size and the instructors background. Some departments enlist all faculty to propose and sponsor one design project each year. Other sources of mentors include faculty in other related departments ( e.g., Materials Science, Food Science, Environmental Engineering, students are double majors in that department. tal work or small-scale construction, funding can be an issue. Most departments have funds available for laboratory equipment and supplies, but funding levels for design of projects. Some departments ask companies to sponsor e.g. may be additional sources for senior design funds. and the number of mentors involved, assessment can be a challenge. Approaches to this issue are discussed by Baker, et al., Rogge, et al., and Davis, et al. is solids processing, which is common in chemical engi neering practice, but is not usually covered extensively in the curriculum. Good references are available from Davey and Garside, Rhodes, Wibowo and Ng, and Hill and Ng. Examples of design projects: contains six complete senior design projects in addition to the extensive list of projects on their website. Shaeiwitz and Turton describe two examples of novel capstone design projects: an ice cream manufacturing process and the design of a transdermal drug delivery patch. In addition, they have developed additional product design projects. includes problem descripand seven practice-session problems. design project that integrates laboratory experiments and computer simulation. outlines a project involving vinyl chloride 2000 criteria. present a biodiesel design project that highlights the potential contributions of chemical engineering to areas such as new energy sources, global warming, and environmental sustainability. AIChE National Student Design Competition problems are also available each year in the fall to department chairs and student chapter advisors. They may be completed by students over the course of 30 days any time during the year (if they choose to enter their report into the competition). An archive of past problems and solutions is available from AIChE. Examples of additional ideas for course content and structure: the World Congress of Chemical Engineering, and NASA sponsor annual design competitions. Kundu and Fowler discuss the use of engineering design competitions to engage students. Often these involve the use of multidisciplinary teams, which is discussed by Redekopp. and Hadley describe the use of wikis in senior design as a project-management tool. Web resources: feature a series of short online videos on Topics in Engineering Design that include com munication in design, design considerations, the design process, and patents and literature. of Engineering, the Markkula Center for Applied Ethics, and the Center for the Study of Ethics in Society have websites with case studies and other materials for teaching engineering ethics. through the Safety and Chemical Engineering Education models. has posted a set of slides on cost estimation. ment costs estimates. lists helpful reference books, periodicals, and trade journals as resources for chemical pricing.

Trouble Spots Trouble spots for this course can include: groups during unit operations lab or in homework groups, senior design is by far the biggest group project that many of them have tackled. Instructors should require design bilities early in the semester. Providing instruction or resources on the phases of team performance, personality types, and learning styles can alleviate potential


314problems. An additional suggestion of Sauer and Arce an Agreement of Cooperation. This agreement will serve as the bylaws of the team and can only be changed with a majority vote of the team members. Administering a peer evaluation tool is essential since much of the course grade will depend on the group project. Instructors might also for example, students could be required to keep a design notebook or submit their individual written contributions. This can be helpful if there is dissent within the team about an individuals contribution. report is likely the most formal and the longest document that students will produce. Even if students have taken a technical writing course, many are overwhelmed and do details. Some campuses have Writing and Speaking Cen ters on campus or in-house technical writing consultants who can assist by providing resources, giving a class lecture, or even reviewing student work. Allowing groups to submit a draft to the instructor a week in advance for a review can identify major problems while still allowing time for correction. want to use software such as (or suggest and procrastination can result in students trying to cram in months of works into weeks or days. Instructors can help students pace themselves by structuring the project into deliverables that are spread over the one or two semesters. For example, in a two-semester sequence in which the projects are assigned in October, students could vember, a status report in February, an oral presentation teams should submit a project schedule and work plan early on as one of the deliverables. Some instructors require students to produce progress reports in memo form periodically during the duration of the project. Finally, depending on the size of the class, the instructor could meet with each team or each project manager regularly throughout the semester to hold them accountable. Author Experiences At North Carolina State University senior design is taught ditional lecture-style class with instructional design content, with students being assigned to teams early in the fall semester and beginning work on their design project, which carries into the spring semester. The spring is focused primarily on the project, with classroom time being devoted to guest lectures that address topics relevant to professional development. Additionally, the author has incorporated the following in the Senior Design course: dress professional development topics, career paths, and non-traditional careers such as medicine, law, pharmacy, business, teaching, or entrepreneurship. Financial plan ning, business and electronic etiquette, and professional dress are issues that students will soon face. Alumni panels on Making the Transition from Student to Em ployee, Changing Jobs, and Graduate School can be a very effective way to address these issues. semester as a status update; this enables advisors to provide feedback that can be incorporated prior to the session and invites students parents, the Industrial Advisory Board members, and current junior students. Starting off with a 2-minute summary of each project and then adjourning to a 60or 90-minute poster session can be an effective way of having students present their work and creates a celebratory environment instead of the high stakes formal presentation. Parent response to this type they have been invited to participate in an event at the university involving their student. This also gives rising seniors an opportunity to see what is required for a senior capstone project. Giving awards for best in show recognizes those students who make exceptional effort and helps rising seniors see where the bar is set. is an easy-to-use online tool that collects and analyzes self and peer evaluations of team members contributions.

315CONCLUSIONS This paper has described some of the best practices for use in the following chemical engineering courses that tradition ally occur later in the curriculum: solution thermodynamics; heat and mass transfer; kinetics and reactor design; process control; and senior design. A common thread is in the deviation from the traditional lecture format. When this is done, the students are given the opportunity to take ownership of their own learning. Popular methods include the use of in-class demonstrations, hands-on activities, tours of the unit operations lab, and seeing a movie or simulation of a concept. Additionally, the softer skills of engineering are ones being an increased emphasis on communication and teamwork skills. It has been our collective experience that incorporating novel methods into the classroom can increase learning as students in the latter part of the curriculum transition from the classroom to the workplace or graduate school. Interestingly enough, the addition of many of these novel methods does It can be overwhelming to consider substantial changes to an established course, but an approach that has worked for the authors is to start with a course that we have taught before. We for the next time we teach the course. As we implement them, we will ask for informal feedback from students. This will often be reinforced through the formal course evaluations. totally different from the original course offering.

318T changes with goals of introducing design earlier in the curriculum and increasing use of experiential learning throughout the curriculum.[1] A modular battery experiment has been developed and used in a sophomore-level mass and energy balance course and a junior-level measurements lab, toward these goals. These experiments assess the students ability to use the techniques, skills, and modern engineering tools necessary for engineering practice, and also allow them to demonstrate their ability to design and conduct experiments, and to analyze and interpret data.[2] An additional goal of this module is to introduce chemical engineering students to battery technology since batteries will play the pivotal role in energy security of modern societies. As an alternative to petroleum, batteries can be used in hybrid electric vehicles (HEVs) and plug-in HEVs to displace petroresources are consumed. Alkaline manganesezinc batteries are the most convenient primary batteries as the source of power for portable electronic and electric appliances.[3] For advanced devices, alkaline MnO2Zn batteries are preferred, which use electrolytic manganese dioxide (EMD) and an alkaline electrolyte (KOH). When used with the electric grid, batteries are able to enhance technologies related to wind power, solar power, and peak load shifting.[5] These topics provide students with exceptional platforms to which they can relate their investigations to contemporary issues. The battery-resistor circuit module allows heat transfer, mass transfer, reactions, circuit theory, heat/mass balances, and product design to be studied in a single module. The module also provides a good preparation for the study of sensors, biosensors, and instrumentation because of its integrated apand virtual instrumentswhich incorporates different aspects of the engineering curriculum.

APPARATUS Figure 1 shows the experimental module composed of cir cuitry mounted on a 1 cm thick Lexan panel. The panel and reinforcing bases are mounted on an oak base. A cabinet allows compact storage of 16 modules and mounting bases. Each module connects to a computer workstation equipped with a National Instruments data acquisition card (NI PCI-6259), ferent experiments to use the same connector interface and respective workstation. Figure 2 provides close-up images of the AA battery connector, resistor bank, and voltages switches. A small ther mocouple embedded in the AA battery holder monitors the battery temperature, which is used for the energy balance. A second thermocouple is attached to the 1-ohm resismeasurement for the energy balance studies. The 1-ohm resistor is connected in series with two other resistors from two resistor banks as selected by the selector switches. Each to be measured. These resistor banks allow variations in an assignment to be made so no two groups or individuals have the same exact experiment. This allows the students to compare their data with other individuals or groups to relate the effect of the changes in resistor load, promoting a more interactive learning environment.[6]


320A series of three switches allows students to measure voltages at different locations in the circuit. Figure 3 provides a schematic of the battery (represented as a voltage source and internal resistance), the two resistor banks with the two associated selector-switches, and the three switches that allow voltages to be measured over the different loads. Operating the module consists of the following steps: 1. Insert and fasten the module on a base at a workstation and connect the 24-pin connector that links the module to the National Instruments based data acquisition system. 2. Place AA battery in the battery holder or connect ancil lary battery to system. position and S3 in the up position to measure voltage across entire load. 5. Hit the start button on LabVIEW VI followed by switch and then click on the LabVIEW VI STOP button. 7. Return module switch to the off position and either repeat or disassemble the experiment. MS Excel and include columns of time, resistor temperature, battery temperature, and voltage (as selected by the switch set about 25 minutes. Subsequent runs take about 10-15 minutes. Typical errors of experiments include use of depleted batteries or operating experiments with switches in the wrong positions. The modules are available in an open-format laboratory for computer workstation lab than a chemical engineering lab. Students are performing experiments (experiential learning) side-by-side with students performing homework and writing reports.[7] This paper explains three different experiment-based projects that can be performed using this module. PROJECT 1: BATTERY-RESISTOR ENERGY BALANCE the 1-ohm resistor that is connected in series with two resistor banks and an AA battery. The students are given minimal guidof the brand name and type (zinc-alkaline) of battery. The students are responsible for the derivation of governing differential equations such as the equation for change in resistor temperature as a function of time, which can be derived from the change in internal energy over time; .[8] The students are to identify how voltage drop and amperage are to estimate parameters such as heat capacity and mass. They are encouraged to use MatLab to solve the differential equations that govern the system. The following are pertinent governing equations: rf During initial predictions the students will typically neglect the convective cooling of the resistor by ambient air or they will struggle to identify how to model the heat transfer. Most students have not had a course in heat transfer, and when they identify the need to apply an engineering science that they have not yet covered they are directed to research the use of [9] The need to take into account the the resistor will become evident when they obtain experimental indicates the need to modify the model battery. The modeling process provides a conceptual learning element because the students can visually relate how changing the heat transfer [2] Figure 3.

The battery and visually understand and verify what happens to the lost energy.[12] For semester-long projects, the students are able to sequentially perform the following: e.g., 30 use these data to prepare a battery performance curve 3. Fully deplete a battery to obtain the amp-hours of energy the battery is able to deliver and compare this to the mass of the battery components (as estimated based membrane surface area (membrane that separates cathode different application (e.g., powering a 20 W light bulb for A project based on these steps provides a valuable experi ential learning process involving: energy balances, transient energy balances, basic circuit theory, modeling vs. predictive simulation, convective heat transfer, analytical vs. numerical solution methods, mass balances, transient mass balances, battery performance curves, and product design.[13] PROJECT 2: EV ALUATING THE INTERNAL RESISTANCE OF A BATTERY A common representation of a battery in circuit theory is as a resistor in series with a voltage source (see Figure 5). The goal of this project is to identify the utility and accuracy of this commonly used model for a battery in a circuit. In AA battery identifying the voltage at 10 seconds for each of several module-set resistances (from high to low). Analysis of the data for this project can be obtained by linear regression of an equation derived as follows. Where: same equation evaluated over the circuit load rather than the theoretical voltage of the battery: or where linear regression can be used to identify VO (constant) and R (slope). Figure 4. A plot of the resistor temperature with superimposition of modeling results (left) and voltage prole of the battery operating with a 3-ohm total resistor (right). For voltage prole plot the experiment was initiated at t=100 s. A A Battery Figure 5. Schematic of a battery as a voltage source in series with an internal resistance.


322Figure 6 illustrates experimental data plotted according to Eq. (6) with an excellent correlation and little scatter. The students are expected to analyze their data and understand why the internal resistance of the battery stays constant, using equations to justify their results. The internal resistance of the battery is relatively constant for data taken at a constant time of exposure to a load. For low resistances, the resistance of the battery will decrease with time due to increased diffusion over-potential as the substrates closest to the membrane are consumed.[15] This trend is seen for the right-most data point, and for this reason, the linear regression was performed without including that data point. Extensions of this project could include evaluating the internal battery resistance at different times the battery is under load.[16] Detailed discussions related to transient diffusions in packed-bed anodes could be used to explain the dependence of the internal battery resistance on time. If the students are able to do the sophisticated modeling, the diffusion in the packed bed could be modeled, converted to diffusion over-potential, and interpreted in terms of a resistor model. PROJECT 3: DIFFUSION AND PERMEABILITY IN MANGANESE DIOXIDEZINC BATTERY The objective of this project is to evaluate batteries that the students assemble. The students are also to relate fundamental differences of the battery performances to properties of the materials and the cell geometry, and to quantitatively cor relate the performance to diffusivity resulting from varying the separator material. The use of a zinc electrode anode is important because of its high open-circuit voltage in the KOH electrolyte, a low corrosion rate, and a low material cost.[17] A schematic of the battery assembly is provided by Figure 7. Prepared anode packing, cathode packing, separator materi als, and premixed electrolyte are provided to the students for assembling the batteries. The electrode packings are volumetrically dispensed into the cell being separated by the separator materials. Alligator clips are used to connect the current collectors of the battery assembly to the AA battery holder points of contact on the experimental module. The experimental procedures include assembling several Zn-MnO2 batteries with different separator materials and evaluate the performance in a 33-ohm circuit. Zinc powder is used as the anode packing in preference to zinc foil or plates because of its large surface area to distribute solid and liquid phases more homogeneously.[18] A high zinc surface-area-tovolume ratio is needed for high-rate capability and since zinc oxide will form on the surface of the zinc as summarized by the following half reactions:[19] Figure 6. Example results from PROJECT 2 and Eq. (6) for evaluating the internal resistance of a battery. The data are for different circuit resistances evaluated with the experimental module. Figure 7. Pictorial representation of a compression cell used for the assembly of MnO2 Zn batteries (left) with picture of assembled cell (middle) and an assembled cell with weight to provide compression (right).


323 Manganese oxide powder mixed with a carbon black is used as the cathode. The carbon is used to increase conductivity of the positive active mass to reduce the internal resistance of the cell.[20] This material may require mechanical processing to maximize reactivity.[21] Potassium hydroxide (1M or 2M) in distilled water works well as the electrolyte because of its high conductivity, and results in a low internal resistance.[22] In the presence of KOH, the discharge behavior of MnO2 occurs in a heterogeneous phase reaction.[23] The separator materials provide the best opportunity to systematically vary a parameter that impacts battery perfor mance. Sheets of permeable material can be punched to sizes that match the inner diameter of the batterys polyethylene sleeve. When preparing the battery, care must be taken to assure that the permeable separator totally separates the anode from the cathode or the battery will short circuit. Filter paper works well as a separator with the experimental parameter to diffusion and greater over-potential losses.[15] It is also a diffusive path between the anode and cathode, the battery voltage will immediately go to zero. The test cell (Figure 7) is basically a compression cell composed of two pistons inside a nonconductive sleeve. The battery is assembled by inserting the base of the compression 1. Place a volumetrically dispersed amount of the cathode material (MnO2 create an even distribution. Potassium Hydroxide is used as an electrolyte in Manganese Diox ide-Zinc batteries because of its strong conductivity. compression cell with the longer piston. 5. Bring the assembled battery back to the module and obtain a pair of wires. Remove the original AA battery, snap off the battery power adapters and connect them to the wires. 6. Attach the alligator clips to the assembled battery and put the two plastic pieces on the top and bottom of the assembled battery, aligning them with the notches. 7. Place a 6 kg weight on the assembled battery and run the program. The weight on the battery compresses the anode and cathode material together, making the age. Figure 8 summarizes representative data for a study of 2, polypropylene as a nonpermeable membrane separating the anode material from the cathode material, keeping the time of the experimental runs constant. The polypropylene mem branes used in this experiment were obtained using the same steep drop in voltage initially and then a steady decline. At a paper) results in a lower voltage delivered to the resistor.[15] Ideally, the voltage for the nonpermeable membrane should involved in constructing a perfect separation seal, there may be some voltage detected due to the seepage and mixing of the anodic and cathodic material around the outer perimeter of the polypropylene membrane. The students should be able to qualitatively understand how increased diffusion distances through permeable materials translate to increased voltage over-potentials.[15] In more advanced applications, the permeability can be related to voltage. Other variations from this experiment include use of battery assemblies with different inner diameters and use of non-permeable separators cut into washer-shapes that vary the cross-sectional area available for diffusion. STUDENT FEEDBACK For Project 1, the students recognized and appreciated how energy is converted from chemical to thermal forms and how transient differential models can relate underlying engineering science (Ohms law, convective heat transfer) to observed phenomena. The most frequent problem encoun-Figure 8. Graph of results showing proposed trend of decreasing voltage with increasing resistance of separator between electrodes.

324tered was a lack of attention by the students to which voltages were actually being measured during the experiment. Project 2 was a simple and straightforward experiment that validates a commonly used model for batteries. Students who expected the need for a detailed analysis based on differential equations were disappointed. Project 3 was effective in getting students to contemplate some more complicated aspects of mass transfer and how mass transfer limits the performance of a battery. The primary concern with Project 3 was that sloppy preparation of the assembled battery could result in inconsistent data. SUMMARY The battery provides an excellent basis for student projects in chemical engineering. The module described in this paper provides a way to deliver experiential learning with batteries in open formats that can be used with a variety of lecture-based courses. The students are able to directly connect with what they observe in the experiential learning because they encounter and frequently use batteries in their day-to-day routines. Different variations of battery-based projects allow students to use energy balances, transient energy balances, basic circuit theory, modeling vs. predictive simulation, convective heat transfer, analytical vs. numerical solution methods, mass bal ances, transient mass balances, battery performance curves, and product design.

325 An Open Letter to SENIORS IN CHEMICAL ENGINEERING Should you go to graduate school? We invite you to consider graduate school as an opportunity to further your professional development. Graduate work can be exciting and intellectually satisfying, and at the same time can provide you with insurance against the ever-increasing danger of technical obsolescence in our fast-paced society. An advanced degree is certainly helpful if you want to include a research component in your career and a Ph.D. is normally a prerequisite for an academic position. Although graduate school includes an in-depth research experience, it is also an integrative period. Graduate research work under the guidance of a knowledgeable faculty member can be an important What is taught in graduate school? of graduate school will often focus on the study of advanced-core chemical engineering science subjects ( e.g. transport phenomena, phase equilibria, reaction engineering). These courses build on the material learned as an undergraduate, using more sophisticated mathematics and often including a molecular perspective. Early in the graduate program, you will select a research topic and a research adviser and begin to establish a knowledge base in the research subject through both coursework and independent study. Graduate education thus begins with an emphasis on structured learning in courses and moves on to the creative, exciting, and open-ended process of research. In addition, graduate school is a time to expand your intellectual and social horizons through participa tion in the activities provided by the campus community. We suggest that you pick up one of the fall issues of Chemical Engineering Education (CEE), whether it be the current issue or one of our prior fall issues, and read some of the articles written by scholars at various universities on a wide variety of subjects pertinent to graduate education. The chemical engineering professors or the library at your university are both good sources for borrowing current and back issues of CEE Perusing the graduate-school advertisements in this special compilation can also be a valuable resource, not only for determining what is taught in graduate school, but also where it is taught and by whom it is taught. We encourage you to carefully read the information in the ads and to contact any of the departments that interest you. What is the nature of graduate research? Graduate research can open the door to a lifelong inquiry that may well lead you in a number of directions dur of a university. Learning how to do research is of primary importance, and the training you receive as a graduate As a senior, you probably have some questions about graduate school. The following paragraphs may assist you


326 student will give you the discipline, the independence, and (hopefully) the intellectual curiosity that will stand you in good stead throughout your career. The increasingly competitive arena of high technology and societys discovery. Where should you go to graduate school? that there are schools that specialize in preparing students for academic careers just as there are those that prepare school or a certain professor with great strength or reputation in that particular area would be desirable. If you are more to your liking; or you might choose a school with a climate conducive to sports or leisure activities in which you are interested. Many factors may eventually feed into your decision of where to go to graduate school. Study the ads in this special printing and write to or view the Web pages of departments that interest you; ask for pertinent information not only about areas of study but also about fellowships that may be available, about the number of students in graduate school, about any special programs. Ask your undergraduate professors about their experiences in graduate school, and dont be shy about asking them to recommend schools to you. They should know your strengths and weaknesses by this stage in your collegiate career, and through using that knowledge they should be a valuable source of information and encouragement for you. Financial Aid living needs. This support is provided through research assistantships, teaching assistantships, or fellowships. If you are interested in graduate school next fall, you should begin the application process early this fall since admission decisions are often made at the beginning of the new calendar year. This process includes requesting application materials, seeking sources of fellowships, taking national entrance exams ( i.e. the Graduate Record Exam, GRE, is required by many institutions), and visiting the school. A resolution by the Council of Graduate Schoolsin which most schools are membersoutlines accepted deadlines for acceptance violate the intent of the resolution). Furthermore, an acceptance given or left in force after the commitment has been made. Historically, most students have entered graduate school in the fall term, but many schools do admit students for other starting dates. We hope that this special collection of chemical engineering graduate-school information proves to be helpful to you in making your decision about the merits of attending graduate school and assists you in selecting an institution that meets your needs.
