C omputer-based control systems have become a
routine feature in the process industry. In order
to be competitive, today's students must be familiar
with the recent developments in control technologies
which are having a significant impact on how com-
plex industrial processes are operated. The first-
listed author of this paper began offering a course in
computer process control in 1975, based on the ma-
terial in the literature"10'30 at that time and his own
perspectives. In the ensuing years, however, the
course has been completely revised in light of the
new and significant developments in control tech-
This paper describes what we believe to be a
modern course in digital computer process control.
Whenever appropriate, recent developments are high-
lighted, and a detailed bibliography of the textbooks
and selected papers used in the course is included at
the end of the article for ready reference.

Pradeep B. Deshpande is professor and a former
chairman of the chemical engineering department
a the University of Louisville. He has twenty years
of academic and full-time industrial experience. He
is the author, co-author, or editor of three textbooks
and sixty papers. He consults for several compa-
nies and offers continuing education courses in
several countries.


P.R. Krishnaswamy received his BSc degree from
Banaras Hindu University (India) and his PhD de-
gree from the University of New Brunswick. His
teaching and research interests include process
dynamics, process control, separation operations,
and fluidization. He has recently shared experiences
in control research during a sabbatical at the Uni-
versity of Louisville and Purdue University.

The goals of the course
are to learn how to design, analyze, and
implement direct-digital control systems for
single-loop and multivariable systems.

An outline of the revised course in shown in
Table 1. For convenience, the course is divided into
three parts: Part 1 is devoted to introductory con-
cepts and the development of a mathematical back-
ground; Part 2 covers the analysis and design con-
cepts of SISO digital control systems; and Part 3 is
concerned with advanced control concepts.
Introductory Concepts and Mathematical Background
The course begins with an introduction to digital
computer control. The essential features of conven-
tional control based on continuous or analog signals
and of digital control, which encompasses hybrid
(discrete/analog) signals, are outlined. The mean-
ings of direct-digital control (DDC), supervisory con-
trol, and distributed control are explained.
Much of the material in the course deals with
DDC concepts, and as a lead-in to the next series of
topics, the elements of a single-loop DDC system are
examined. We point out that the DDC-loop consists
of the usual elements of any control system-namely,
the process, a measurement-device transmitter, and
a final control element. In addition, a DDC system
has an analog-to-digital (A/D) converter that samples
measured process outputs at a sampling frequency
selected by a real-time programmable clock, a digi-
tal computer or digital controller, and a digital-to-
analog (D/A) converter that converts computer-gen-
erated discrete control commands into continuous
signals for operating the final control elements.

The goals of the course are to learn how to de-
sign, analyze, and implement direct-digital control
systems for single-loop and multivariable systems.
It should be emphasized that the availability of con-
trol computers allows the designer to implement
control methodologies that are either impractical or
impossible with conventional control hardware.
Examples include dead-time compensation, feed-
forward control, synthesized digital control algo-
rithms, and model predictive control.

The sequence of lectures is devoted to the study
of each element of the DDC loop. The first among
them is concerned with computer-control hardware
and software. The hardware description includes the
central processing unit, the main memory/bulk
memory, the computer input/output (I/O) devices,
process I/O, the A/D and D/A converters, and a real-
time programmable clock. The software concepts
include an introduction to assembly-level program-
ming, real-time Fortran, and Basic. At the Univer-
sity of Louisville a PDP 11/03-system has served our

Design and Analysis of Digital-
Control Systems

The discussion of pulse-trans-
fer functions and open-loop re-
sponses leads us into an exciting
topic-the notion of an impulse re-
sponse (IR) model, which enables
us to predict the process output at
the next sampling instant from past
inputs through use of the equation

YK+1 = hi uK+-i

Fall 1991

Beginning with the definition of the pulse-trans-
fer function, G(z) = Y(z)/U(z), the instructor can eas-
ily derive Eq. (1), as shown for example in Desh-
pande and Ash.71- IR-type models have distinct ad-
vantages: they can be derived from easily-available
step response data; the response curve need not be
fitted to a structured model and the order of the
process is not important; and the use of an IR-type
model considerably simplifies the evaluation of closed-
loop responses by computer simulations.
The next topic is the design of digital-control al-
gorithms for SISO (Single-Input Single-Output) sys-
tems. While controllers can be designed by a number
of methods, we believe that the direct-synthesis
method is best suited for this course. The basic idea
is to solve the closed-loop pulse-transfer-function
equation for the controller, giving

D= Y/R 1 (2)
1-Y/R (

The closed-loop response is specified according to
the equation
S= FG, (3)
By selecting the desired expressions for F, sev-
eral well-known control algorithms can be obtained;
for example, the choice of F = 1 gives deadbeat con-
trol. Through use of the CAI software, students
quickly learn that deadbeat control can give rise to
rippling behavior of the controller output. Further-
more, deadbeat controllers are very sensitive to
modeling errors.
The choice of a first-order lag for F gives a Dahlin
algorithm. The instructor can easily show that a
Dahlin algorithm is the same as an internal-model-
control (IMC) algorithm if a first-order filter is em-
ployed in the latter. It would also be helpful to derive
the IMC structure from the sampled-data control
structure and show that the two representations are
equivalent. Once the IMC structure is derived, one
can go over the stability theorems and design IMC
controllers for a variety of processes-including those
that exhibit dead-time and inverse response.
In the discussion of IMC, the instructor can de-
rive the Smith Predictor algorithm and point out the
similarities between the two approaches. Also,
through simulation exercises, the instructor can show
that the latter does not tolerate modeling errors well
and that the tuning of the Smith Predictor-based
PID controllers becomes difficult in the presence of
modeling errors.
At one end of the spectrum of control equality

there is a notion of perfect control (deadbeat con-
trol). IMC is an algorithm that delivers perfect con-
trol in the absence of modeling errors. In the pres-
ence of modeling errors, however, the designer must
back away from the notion of perfect control in favor
of robustness, by choosing an appropriate filter.
At the other end of the spectrum of control qual-
ity there is the notion of open-loop control. Simpli-
fied model-predictive control (SMPC) and conserva-
tive model-based control (CMBC) are algorithms
which assume that at worst the controller should be
able to provide a set-point response that is as good
as the open-loop response. These algorithms are de-
rived as follows: the open-loop behavior of an open-
loop stable process is given by
Y_ 1 (4)
R K,
Substituting for Y/R from Eq. (4) into Eq. (2) gives

D=M (5)
The choice of Eq. (5) for the controller will deliver a
set-point response that is the same as the normal-
ized open-loop response. The response can be speeded
up by introducing a tuning-constant ax, giving the
SMPC algorithm
D= P (6)
K -G
SMPC features a single-tuning constant that can be
found by offline optimization. Dead-time compensa-
tion can be incorporated by modifying Eq. (5) accord-
ing to A



A 1- pz (8)
Equation (7) represents the CMBC control law.
CMBC also features a single-tuning constant P whose
value can be found by offline simulation.
In the discussion of various control algorithms,
the students are reminded that the algorithms which
give the best servo responses are not necessarily the
ones that are best for regulatory control. Further-
more, the design work assumes that the processes
are linear, but in reality they are not. Consequently,
the algorithms that give the best performance in
simulation work may not be the best when they are
implemented on real-life nonlinear processes.
The next topic of discussion is stability. Stability
concepts relating to sampled-data systems can be
effectively derived by utilizing the relationship be-

Chemical Engineering Education

tween the Laplace transform operator s and the z-
transform operator z. The discussion of stability con-
cludes with a method for finding the roots of the
characteristic equation in the z-domain.

Advanced Control Concepts
The next topic is process identification. The tra-
ditional methods which we cover are step testing,
pulse testing, and fitting of models to frequency-
response plots. An ideal method should identify proc-
ess dynamics from a test that does not force the
process away from the steady-state operating condi-
tion. One such method that meets these needs is the
relay method in which a relay perturbs the process
and the resulting process output/input data provide
the ultimate frequency and ultimate gain of the sys-
tem. These data lead to optimized tuning constants
of a PID-type controller.
Another method, called dynamic matrix identifi-
cation, calls for perturbing the process by a series of
up-and-down step changes in the input U(z) around
the steady state, given by the equation
U(z)-= U + U1z1 + U2z-2 + U3Z-3 (9)
Then, in the light of the impulse response model
Y(z) N
Y(z) = hz (10)
U(z) i=1
the output is given by
Y(z)= 0+ hlUoz-1 + (h2U0 + hU)z-2 +... (lla)

= 0 + Yzz- + Y2z-2 +... (lib)
Equations (lla) and (lib) show that the impulse
response coefficients can be computed from the ex-
perimental input and output data.
The last method covered which is suited to use in
a noisy environment is time-series analysis. In this
method the process is described in two parts: one
accounts for the model and the other is a noise term
that accomodates the effect of unmeasured load dis-
turbances. A PRBS (pseudo random binary sequence)
signal is applied to the process and the analysis of
the input-output data gives the model. Time con-
straints prevent an in-depth treatment of the the-
ory, but the software available (e.g., Matlab: see also
Reference 21) can be effectively used to illustrate the
The next topic is practical nonlinear control. The
treatment is restricted to a conceptually simple prac-
tical method which appears to have considerable
Fall 1991

potential. It is well known that the closed-loop re-
sponse of many complex nonlinear SISO systems
can be described by a linear second-order transfer
function, given by

Y(s) r1s + r12
R(s) s2 +r1S+ 12
or, in the time domain
dY = nE+n 2JE dt



where E = R Y.
The terms T1, and 12 determine the shape of the
response. Now, the nonlinear process is described by
a nonlinear differential equation of the form

dY f(yn, n Y, eAY, etc.)+U (14)
Equating Eqs. (13) and (14) gives the nonlinear con-
trol law
U=-f(Yn, nY,eAY,etc.)+Tl1E+l2 JEdt (15)
If the resulting control law turns out to have
undesirable properties, such as ringing or constraint
violations, then a minimization problem based on
the difference between actual and the desired values
of the derivative dY/dt is solved to derive the control
law. Note that this analysis of nonlinear control is
based on continuous-time systems. The system
equations would have to be discretized for use in a
digital-computer-based control system.
The next set of topics falls into the category of
what is commonly referred to as advanced control
concepts. The first topic to be covered is adaptive
control and self-tuning. Time limitations permit only
a brief introduction. The need for adaptive control
arises due to changing process characteristics. Auto-
tuning, gain scheduling, self-tuning regulators, and
model-reference adaptive control are examples to be
covered. The use of a relay to identify the ultimate
gain and ultimate period of a proportional controller
in auto-tuning has already been mentioned.
Feedforward and cascade control are the next
topics to be covered. Feedforward control is meant
to improve the response of feedback control systems
in the presence of disturbances in process loads,
while cascade control is meant to arrest the detri-
mental effect of disturbances in the manipulated
The final topic to be covered deals with multi-
variable control, which includes the topics of inter-
action analysis and variable pairing, multiloop con-
trol for modestly-interacting systems (including PID

controllers designed by the biggest log modulus tun-
ing method), multiloop IMC and CMBC/SMPC con-
trollers, explicit decoupling in conjunction with PID
controllers, reference systems decoupling, and multi-
variable model predictive control. Model predictive
control includes dynamic matrix control, model algo-
rithmic control, and predictive IMC.
Model predictive control techniques utilize step-
or impulse-response models of the process. These
models are used in conjunction with optimization
techniques to calculate controller outputs. It should
be emphasized that complex multivariable processes
must invariably be operated in the vicinity of con-
straints. Therefore, students must have familiarity
with some methods, such as linear and quadratic
programming for solving constrained multivariable
optimization problems and how they are used in
conjunction with model predictive control. Simula-
tion examples can be used to illustrate the concepts.
This concludes the course. The first-listed author
offers the course regularly at the University of Lou-
isville and as an intensive short course for industry
in the U.S., Europe, Kuwait, and India. The reac-
tions of the participants have always been favorable.

to the editor


Dear Editor:

A ranking of the most highly regarded doctoral
programs in chemical engineering was presented in
the November 1983 edition of Changing Times."'
This ranking was based on a study published by the
National Academy of Sciences.12' For the ranking re-
ported by Changing Times two key measures of repu-
tation from the National Academy study were com-
bined: 1) "faculty quality" assessed how chemical
engineering professors around the country rated their
peers in the same discipline, and 2) "program qual-
ity" assessed how well the faculty thought each pro-
gram educated research scholars and scientists.
Changing Times combined these two measures and
derived a ranking of the top ten percent of the pro-
grams in chemical engineering. If one goes by the
assumptions of the Changing Times article, the eight
schools with the highest combined scores represented
the "academic elite" in chemical engineering-the
"best" programs in the country.
Given the subjective nature of the evaluation
process which produced the National Academy rat-
ings, I decided to examine the composition of the
faculties of the top eight schools. I suspected that
these departments would be substantially linked to
one another through the hiring of one another's
graduates, hence enhancing one another's reputa-
tions. I also expected that among the academic elite
there would be a high degree of academic "inbreed-
ing"-the hiring of graduates from one's own pro-
I used the American Chemical Society Directory
of Graduate Research 1989 to examine the full-time
faculties of the eight highest-ranked chemical engi-
neering departments. An item of primary interest
was where the full-time faculty members at these
institutions had received their doctoral degrees. It

soon became obvious that there were numerous in-
terrelationships among the departments in terms of
where the faculty had received their doctoral de-
The following table lists the top-ranked depart-
ments and indicates the percentages of full-time fac-
ulty who received their doctoral degrees from one of
the "elite" departments on the list (which includes
those who received their degrees from the same de-
partments where they are currently on the faculty).

2 Percentage of faculty who received PhD.s from the program in which they are now
SNumber of PhD recipients from the programs who were on the faculty of one of the
top-ranked programs in 1989.

As can be seen in the table, in all of the top-
ranked departments a substantial proportion of the
faculty received PhDs from one of the "academic
elite." The California Institute of Technology and
the University of Illinois had the highest percent-
ages of degree holders from the top-ranked depart-
ments (75.0%), and the University of Minnesota had
the lowest (50.0%). At most of the schools, anywhere
from one-half to three-quarters of the faculty gradu-
ated from one of the prestigious programs.
The table also addresses academic inbreeding
among the top-ranked chemical engineering pro-
grams. Berelson141 and Caplow and McGee561 have
demonstrated that a high degree of inbreeding among
elite schools is not accidental. According to both stud-
ies, if elite programs are to maintain their prestige,
they cannot hire a large number of PhDs from lower-
ranked departments, and this would include PhDs
from upwardly mobile "middlemen" programs where
elite credentials have yet to be established. In his
study of sociology departments, Gross161 found that
the higher the prestige of a department, the greater
the proportion of "home-grown" graduate faculty.
With some modifications, Shichor's study[71 confirmed

Gross' findings. Shichor found the relationship be-
tween departmental inbreeding and the prestige of a
department to be curvilinear, with the highest and
lowest ranking departments having the highest rates
of inbreeding while mid-level departments were found
to have the lowest rates.
As can be seen from the table, in 1989 the school
with the largest percentage of its own graduates on
its full-time chemical engineering faculty was Mas-
sachusetts Institute of Technology (42.4%). The Uni-
versity of Minnesota, California Institute of Tech-
nology, and the University of Illinois had not hired
any of their own graduates.
The table also presents the number of PhDs pro-
duced from each department who were full-time fac-
ulty members of one of the elite departments in
1989. MIT had thirty-one of its graduates in faculty
positions at the elite departments, and Berkeley was
next with seventeen. Illinois had the least with four.
I think that graduate departments in chemical
engineering (or in any discipline) must rely to a
large extent upon their reputations in order to at-
tract highly qualified faculty and graduate students
to participate in their programs. The eight chemical
engineering graduate programs that were top-ranked
in the 1981 National Academy study are undoubt-
edly strong programs. I certainly do not wish to
argue that they are not. However, the data suggest
that a number of subjective factors influence the
procedure by which academic departments are
ranked. Primarily, I contend that a rather small
group of institutions (eight in this instance) tend,
consciously or unconsciously, to enhance one an-
other's reputations by hiring one another's gradu-
The Changing Times article used two measures
of reputation in order to establish its list of the
"best" graduate departments: how professors rated
their peers in the same discipline, and how well the
faculty thought each program educated research
scholars and scientists. These criteria are vitally
linked; when elite faculty are asked to rate their
peers at other schools, they are (to a large extent)
rating their former professors or students. There are
a total of 153 full-time faculty in the chemical engi-
neering elite, and 97 of them (63.4%) graduated from
one of these distinguished programs. Clearly, it is in
their best interest to rank their alma maters highly.
The remarkable stability in the ranking of elite
programs over the last few decades suggests that
not only do elite faculty rate their own programs
highly, but so also do large numbers of faculty from

Chemical Engineering Education

less prestigious programs. Several factors may ex-
plain this phenomenon. On the one hand, the data
suggest that the consistently high rankings of elite
programs are due to the large number of graduates
that those very same programs put into the disci-
pline each year. While they place some graduates in
other elite schools, most descend into mid-level
schools or less renowned institutions where they
continue to subjectively rank their alma maters as
the very best. The high number of elite school gradu-
ates at all levels also seems to enable them to play a
disproportionate role in shaping opinion within the
There is another way of explaining the relative
stability in the ranking of elite programs over time.
Obviously, there are not enough faculty from elite
schools at middle and lower level programs for them
to maintain the high ranking of their alma maters
without some support from their non-elite colleagues.
Tradition may be a partial explanation for the non-
elite's acceptance of their inferior status. Elite schools
have been accorded high esteem for decades, and
these traditions typically have gone unchallenged.
A more likely explanation, however, is that the
non-elite, in a classic example of Marxian false con-
sciousness, E' have adopted their elite peers' assess-
ment that the letters' programs and faculties are
superior. Buttressed by only a few subjective gov-
ernment surveys and contact with a handful of indi-
viduals from elite programs, the non-elite have not
only accepted but also even promoted the notion that
elite graduate programs are deserving of high es-
teem, whereas others, including their own, are not.
Ultimately, I think it should be asked: Are the
eight highest-ranked programs indeed the best PhD
programs in chemical engineering, or do they com-
prise an "academic elite" with a large number of
faculty members in the discipline and an obvious
interest in perpetuating the present ranking sys-
tem? I believe that data suggest that the latter is
Two final comments seem in order. First, I con-
tend that because of their subjectivity, current rank-
ing systems are a detriment to the discipline. They
may impede professional mobility, reward status over
achievement, and result in programs of lesser re-
nown being bypassed, even though they may merit
as high or higher recognition than do those of the
elite. Second, I believe that current, subjective rank-
ing systems incorporate serious distortions and mis-
representations. Because they have the potential to
do as much harm as good, I recommend that as they

are presently constituted, subjective systems of de-
partmental ranking should be routinely ignored.

The Unexpurgated Story of a Long-Range Program of

Research in Combustion

The University ofPennsylvania
Philadelphia, PA 19104-6393

The presentation of experimental and theoretical
findings in a journal usually implies that the
path of the investigation of which they are the cul-
mination was well-planned and straightforward.
Such is rarely the case, however, particularly with
exploratory research for which unanticipated results
are the justification and the reward. Indeed, the
most useful results are often the consequence of a
deviation from the original objective in order to ex-
plain, resolve, or explore an apparent anomaly. Most
discoveries and innovations so arise.
This paper utilizes the history of a long-term (40-
year) investigation of combustion inside tubes to
illustrate the true, unvarnished path of exploratory
research with all of its turnings, windfalls, misdirec-
tions, triumphs, and disasters. The primary objec-
tive of this recounting is to persuade doctoral stu-
dents (and perhaps their advisors) that the anoma-
lies observed in experiments or in comparing experi-
ments and theoretical solutions are not to be ig-
nored, hidden, or deplored, but rather should be
taken as a signal of possibly important unknown be-
havior that may actually justify a diversion in, an
addition to, or even a complete redirection of the
research. A second, related objective is to demon-
strate the helpful (and indeed, essential) role of theo-
retical modeling in explaining experimental results
and, particularly, anomalies.

Stuart W. Churchill is the Carl V.S. Patterson Pro-
fessor Emeritus at the University of Pennsylvania
where he has been since 1967. His BSE degrees (in
ChE and Math), MSE, and PhD were obtained at the
University of Michigan where he also taught from
1950-1967. His research has encompassed many
aspects of heat transfer as well as combustion. He is
currently completing a textbook on turbulent flows.

The research program that supported me as a
graduate student involved the ignition of solid pro-
pellants by a stream of gas at high temperature. We
rationalized that a mixture of 02 and inert gases was
equivalent in that respect to the products of combus-
tion of a primer. My curiosity was provoked and
unsatisfied as to the possible effects of combustion
itself on heat transfer, and sometime thereafter I
persuaded Donald W. Sundstrom to investigate this
subject for his doctoral research. Supported equip-
ment-wise by an unrestricted grant from the Esso
Engineering and Research Company, we chose a
geometry unrelated to the ignition of propellants but
of more general interest-namely heat transfer from
a flame of premixed air and propane stabilized on a
central bluff body inside a 25.4-mm-ID stainless-
steel tube. The choice of combustion inside a tube,
which was arbitrary on our part and at that time
relatively unexplored, proved to be serendipitous not
only in terms of the immediate results, but also in
precursing the entire subsequent chain of events
described herein.
Although acoustic resonance was not anticipated
to be a significant factor, Sundstrom observed a cor-
relation between the local rate of heat transfer and
the aurally-sensed amplitude of the noise generated
by the flame, and he promptly acquired the appro-
priate instrumentation for characterization of the
latter. The local rate of heat transfer was found to
depend primarily on the pattern of flow generated
by the combustion, but that pattern was found in
turn to be influenced strongly by the flame-gener-
ated acoustics.1" The latter were rationalized to be
initiated by the periodic shedding and combustion of
the vortices generated by the flameholder, and to be
enhanced by the resulting resonant oscillations in
pressure. Theoretical calculations indicated that the
frequency of the oscillations corresponded to the lon-

A study of the literature on flame-generated os-
cillations suggested that the "screeching" combus-
tion associated with jet engines might have a similar
cause, but be due to tangential rather than longitu-
dinal oscillations. Sundstrom was unable to produce
screeching combustion in his apparatus, but Wil-
liam N. Zartman, the following student, determined
from crude, preliminary experiments with a flame
stabilized on a bluff body inside plain, uninstru-
mented and uncooled pipes of various sizes, that
screeching combustion could be made to occur for
pipe diameters greater than 100 mm. Hence, stain-
less-steel pipe with a diameter of 127 mm was cho-
sen for his doctoral research. Amplitudes of as great
as 160 db at a frequency of 4125 Hz were attained.
The research itself documented a linear increase
in the local heat-transfer coefficient within the tube
with the amplitude of the resonant oscillations, and
indicated that these oscillations could be dampened
by the installation of 1/4-wavelength tubes radially
at the theoretically-identified nodes.[21 The work of
Zartman was distinguished in character by his use
of inexpensive and brief preliminary experiments to
choose the conditions for detailed study and by the
use of theoretical analysis not only to explain but
also to develop a method for controlling the experi-
mentally-observed behavior.

In order to eliminate the source of the acoustic
resonance, rather than just dampen it, I speculated
on the possibility of stabilization without backmix-
ing. I thereupon persuaded two students to attempt
to model (as a term project in a seminar-type course)
the stabilization of a flame inside a ceramic channel
by thermal feedback only. One of them, Ward O.
Winer, concluded from a very idealized model based
on the postulates of plug flow with perfect radial
mixing, an infinite rate of combustion following the
attainment of an arbitrary temperature of ignition,
and a tube of infinite length with an emissivity of
Fall 1991

unity and a negligible conductivity, that a flame
could be stabilized within the channel by wall-to-
wall radiation only.

The promising (if somewhat hypothetical) result
of Winer gave me the courage to persuade Thomas
D. Bath to undertake experimental research on ra-
diative stabilization in a ceramic tube for his doctor-
ate. Bath succeeded in establishing a flame from
premixed propane vapor and air inside a 25.4-mm
ceramic tube, but (as contrasted with the experi-
ments of Sundstrom and Zartman) the temperature
of the wall approached that of the flame. As a conse-
quence, every tube cracked during the process of
startup, raising the spectre that the stabilization
might be due to recirculation downstream from the
crack. We were disappointed that the flame fluctu-
ated and was somewhat noisy, but concluded this
behavior might also be attributable to the cracks.
Because of the poor definition of the conditions in-
side the tube, we chose not to publish these results
in the archival literature.
As a consequence of such a discouraging experi-
ence, I might not have resumed research on ther-
mally-stabilized combustion at the University of
Pennsylvania (where I had now relocated) had I not
discovered, as a consultant to the Marathon Oil
Company, that the ceramic Wulff furnace elements
used by them for the thermal cracking of methane
would withstand (because of their considerable po-
rosity) temperatures and temperature gradients as
high as those encountered in the experiments of
Bath. Marathon graciously donated several elements
for our research. These consisted of 254-mm-long
blocks perforated by round 9.52-mm holes in a trian-
gular array. Cementing three such elements together
produced a burner with seven channels. The central
one was used for the measurements, and the outer
six functioned as guard heaters.
With this promising device in hand, I persuaded
Joseph L.-P. Chen to undertake as his doctoral re-
search a continuation of the work begun by Bath.
Considerable patience and ingenuity were required
to establish a stationary flame in this ceramic block
the first time; without the confidence generated by

the idealized theoretical solution of Winer and the
experiments of Bath with tubes, we might not have
persisted through the many failures. Once we learned
how, establishing a stationary flame became routine
(if time-consuming), and Chen determined by tedi-
ous trial and error the limits of flow for a stable
flame of premixed propane and air within the block.
For all of these conditions, the process of combustion
was noticeably clean, quiet, and non-fluctuating as
compared to conventional processes, all of which
involve backmixing-by diffusion in laminar flames,
by recirculation in bluff-body-stabilized flames, and
by turbulent fluctuations in jet-mixed flames.
Following this phase of the work, Chen decided
to investigate the dependence of the range of stable
flames on the diameter of the channels by cementing
in ceramic liners with an ID of 4.76 mm. Although
combustion could be established in these smaller
channels, the flame was (to our surprise and disap-
pointment) diffuse and oscillatory. This difference in
behavior was clearly associated with the regime of
flow upstream from the flamefront, being laminar in
the 4.76-mm channels and barely turbulent in the
9.52-mm ones.
In retrospect we were lucky. If the original chan-
nels in the Wulff furnace elements had been 8 mm or
less in diameter, we might have abandoned this line
of research as uninteresting owing to the relatively
poor combustion which occurs in the laminar re-
gime. Instead, because of the clean-cut behavior ob-
served in the 9.52-mm channels, we realized that we
had discovered a new and promising process of com-
bustion.131 Even so, we did not yet even begin to
appreciate all of its unique characteristics.

Despite the above-mentioned accomplishments, I
was somewhat critical of Chen because of his failure
to attain a high degree of reproducibility for his data
(which is an essential requirement of good experi-
mental work), particularly in the determinations of
the location of the flamefront for various conditions.
I was also somewhat impatient with his failure to
produce a numerical solution for an extended theo-
retical model. Both of these judgements proved to be
quite unfair. As shown by later work, the irrepro-
ducibility was inherent in the process. As regards
the numerical solution, the model involved an inte-
gro-differential equation with split boundary condi-
tions for the temperature in the solid phase, to-
gether with differential equations for the tempera-
ture and composition in the gaseous phase, and was

truly formidable at that stage of development of
numerical methods.
Despite no previous experience with either com-
puters or numerical methods, Chen eventually did
devise an ingenious and successful procedure that
produced a solution in close accord with his experi-
mental results. The model incorporated a number of
idealizations including global kinetics, plug flow, and
perfect radial mixing, but only one significant em-
piricism-the effective energy of activation, which
he chose to force agreement with respect to location
of the computed and measured longitudinal profiles
in temperature in the ceramic block.
One disturbing aspect of the numerical proce-
dure was the dependence of this effective energy of
activation on grid size. Even more startling was the
prediction of six additional stable solutions for the
same external conditions. Three of these multiple
states were closely grouped upstream and four down-
stream in the tube. We speculated in print[4] that
two of the seven solutions, i.e., one from each group-
ing, might have physical validity by analogy to those
for a perfectly mixed exothermic reactor, but that
the other five were probably artifacts of the approxi-
mate and iterative method of solution-a not un-
common experience with integral equations.
The numerical solution revealed that the tem-
perature of the burned gas just beyond the flamefront
exceeded the adiabatic flame temperature. This re-
sult, which is perhaps startling at first glance, is not
a violation of the second law of thermodynamics but
simply a consequence of the refluxing of energy back-
ward across the flamefront by wall-to-wall radiation
and in-wall conduction. The temperature of the
burned gas leaving the burner is of course below the
adiabatic value by an amount equivalent to the total
heat losses from the ceramic block to the surround-
ings. The calculations revealed that about one-third
of the thermal feedback was by conduction in the
ceramic block and two-thirds by wall-to-wall radia-
tion, and indeed that (contrary to the approximate
model of Winer that encouraged this line of research)
the contribution of thermal conduction through the
ceramic block was essential to the existence of a
stable flame.
Chen also carried out calculations for a variety of
parametric conditions beyond the range of his ex-
periments. His prediction of the limiting flamespeeds
for a 25.4-mm channel agreed closely with the meas-
ured values of Bath, validating them retroactively.
Numerical calculations with Chen's model were not
attempted for a 4.76-mm channel since the postu-
lates of plug flow and perfect radial mixing were

obviously not applicable for the laminar regime.
Chen's experimental work revealed a new proc-
ess of both intrinsic and practical value, and his
modeling and numerical solutions were a valuable
complement. Most of the characteristic elements of
behavior of thermally stabilized combustion were
totally unexpected when we began. Luck, my per-
haps excessive confidence in the asymptotic solution
of Winer, and the persistence and ingenuity of Chen
(both experimentally and theoretically) were all es-
sential to the great success of this research.
Melvin H. Bernstein undertook the task of search-
ing for the predicted multiple stationary states as
his doctoral researchE51 with a newly-acquired set of
Wulff furnace elements. First, he reproduced Chen's
data within its band of variability. Then he searched
for and found the expected second stationary state,
then the five more which we had not expected de-
spite their prediction by the numerical solution. One
curious and (to this day) unexplained aspect of these
measurements was the observation of four closely
grouped upstream states and three even more closely
grouped downstream states, whereas Chen's model
predicted four downstream and three upstream.
The Mobil R&D Company responded favorably
and graciously to my request to analyze several
samples of the burned gas from Bernstein's experi-
ments since we did not then have equipment for
such measurements. We were excited to learn from
these analyses that the thermally stabilized burner
(TSB) produced no residual hydrocarbons since (as
contrasted with all conventional burners) none of
the fuel bypasses the zone of high temperature. Also,
the TSB was found to produce essentially no "prompt"
NO in the flamefront owing to its negligible thick-
ness, and to produce exceptionally low concentra-
tions of "thermal" NOx (5-30 ppm) thereafter owing
to the short post-flame times of residence. The con-
centration of total NOx was found to be directly pro-
portional to the post-flame residence time, as would
be expected for a zero-order reaction. On the other
hand, these low values of NO constituted a tradeoff
with CO in that the same post-flame residence times
were insufficient for complete oxidation to CO2.
I encouraged Bernstein to improve upon Chen's
computer program, but he was unable to make even
the original one operational. Finally, in desperation
and impatience I telephoned Chen and solicited his
help. He offered to retest his program as a first step
and to call back the next day. After a suspicious
Fall 1991

delay of several days he called and shamefacedly
reported that he had inadvertently printed a
preliminary inoperable computer program in his
dissertation, but that he was sending us the
original, correct one, which he had retested and found
However, Bernstein, in his struggles with the
inoperable program, had discovered two significant
errors. They were found to exist in the "original"
program as well. Both of the errors inflated the heat-
transfer coefficient for convection downstream from
the flamefront as estimated from a standard correla-
tion. When these errors were eliminated, no stable
solutions could be computed. After much agony, we
concluded that an inexplicably high coefficient was
necessary to produce stable solutions, at least with
Chen's model. (It took another decade of work to
explain this anomaly.)
We were now in the unbelievable situation of
having found seven stationary states experimentally
only because we were inspired to search for them
by a theoretical model which now appeared to be
invalid! But for the errors in his computer program,
Chen might never have attained a solution, and
Bernstein would never have searched for or found
all of the six additional stationary states. (The sub-
sequent history of our research suggests that we
would have eventually searched for and found at
least one additional state.) In retrospect, the irrepro-
ducibility of Chen's data arose from the establish-
ment on successive days of different members of the
closely-grouped set of upstream states. The particu-
lar state depended upon minor variations in the
process of startup that we had no reason at the time
to consider relevant.
Again, luck was obviously an important element
in our success, but two lessons stand out. First, the
interaction of experimental and theoretical work is
often synergetic and may produce more than either
one alone. Second, independent efforts by two or
more investigators may identify and explain anoma-
lies that escape attention and/or resolution by only
one. These two lessons have been reinforced by our
subsequent experiences as described below.

As his doctoral research, Byung Choi extended
the investigation of thermally stabilized combustion
to liquid fuels by burning droplets of hexane gener-
ated by vibration of a capillary tube. Stroboscopic
visualization of droplets of water in a preliminary
experiment was utilized to confirm a theoretical

model, which was then used to guide the unobserved
production of a chain of uniformly-sized and uni-
formly-spaced droplets of hexane within the burner.
His results agreed remarkably well with those of
Chen, suggesting that the thermally stabilized burner
was essentially fuel-independent insofar as the drop-
lets were small enough and volatile enough to evapo-
rate completely ahead of the flamefront.
However, Choi was not able to establish more
than one stationary state for a given set of condi-
tions.E61 He extended Chen's model to encompass
evaporation of the droplets and devised a greatly
improved but still approximate method of solving
the integro-differential equation (which proved to
have general utility even outside of combustion and
for solving purely integral equations as well)." With
this method, the effective energy of activation re-
quired to match the computed location of the
flamefront with the experimental one was not de-
pendent on grid size. He avoided the "stiffness" asso-
ciated with the steep gradients of temperature and
composition in the flamefront by using steps in com-
position rather than distance in the numerical inte-
gration. Even so, extreme sensitivity was encoun-
tered in the computational procedure; the stable so-
lution was found to be dependent on the eighth sig-
nificant figure of the temperature of the wall at the
inlet, which quantity was used as the variable of
The numerical solution provided a complete, es-
sentially fuel-independent locus of flamefronts ver-
sus the rate of flow of fuel and air in close agreement
with the data for both gaseous propane and droplets
ofhexane.18s However, this relationship predicts only
two stable locations for a given fuel-to-air ratio and
rate of flow, one near the inlet and one near the
outlet of the channel. The other five stable states
predicted by Chen and observed by Bernstein are
only slightly displaced from this locus, and we now
postulate that the slight approximation which expe-
dited the process of solution eliminates the fine struc-
ture which would have resulted in their prediction.
As contrasted with blowoff and flashback for con-
ventional burners, the above-mentioned locus of sta-
bility predicts another unique characteristic for
thermally stabilized combustion: for increasing rates
of flow, both of the computed stable locations of the
flamefront are predicted to shift inward toward a
common point near the longitudinal midpoint of the
channel followed by extinguishment; for decreasing
rates of flow, both of the computed stable locations
are predicted to shift outward to the respective ends
of the channel, with extinguishment occurring some-

what short of the ends. The predicted limiting be-
havior was not tested by Choi, even for the single
downstream stable flame he established, because of
the difficulty of adjusting the fuel and air propor-
tionately while maintaining the same size and spac-
ing for the droplets.
Choi also computed the chemical process of com-
bustion using a global model for conversion of the
hexane to CO and H20, and pseudo-steady-state free-
radical models for the formation of NO and the
oxidation of CO. The predicted concentrations of NO
were greatly in excess of, and those of residual CO
were grossly below, the measured values, suggesting
that these models were inadequate, at least for the
high temperatures and minimal backmixing encoun-
tered in thermally stabilized combustion.
The previously noted lessons concerning the con-
duct of research were reinforced in a slightly differ-
ent context by the work of Choi. Again, a fresh ap-
proach by a second investigator, this time in solving
the general model with some extensions, was very
productive. The resulting solution included a com-
plete locus for the stable flamefronts, and thereby
the prediction of unique and unexpected limiting
behavior. It also provided theoretical confirmation
for the observed fuel-independence of the thermally
stabilized burner. In addition, theoretical modeling
of the atomization was a critical element in the de-
sign of the experiments.

John W. Goepp, as his M.S.E. thesis, and with
the help of Shu-Kin (Harry) Tang, completely recon-
structed the experimental apparatus of Choi in or-
der to provide more precise and flexible control of
the rates of flow of air and hexane, and thereby
facilitate the search for multiple stationary states in
that system. Wulff furnace elements were no longer
available, but a geometrically equivalent burner was
cast from a commercial ceramic cement. Equipment
for online analysis for NO, COx, CO, CO,, and 02
was added. The improved control permitted iden-
tification of as many as three upstream and two
downstream multiple stationary states with hexane.?g9
Presumably, two more might have been found with
better control and care. The locations of all of
these stable flamefronts were in good accord with
the predictions of Choi. The online chemical analy-
ses were in agreement with those by Mobil, elimi-
nating the nagging possibility that the latter
were affected by the storage and transportation of

samples in Teflon bags.

Tang utilized the improved apparatus constructed
by Goepp and himself to investigate as his doctoral
research the effects of an addition of small concen-
trations of fuel-nitrogen and fuel-sulfur to hexane on
the formation of NO He covered a more complete
range of residence times than his predecessors by
making periodic, pseudo-steady-state measurements
while the flamefront drifted upstream from a stable
location near the outlet or downstream from one
near the inlet as a result of a perturbation in the
rate of flow. He also investigated a wider range of
equivalence ratios (fuel-to-air ratios divided by the
stoichiometric fuel-to-air ratio). He found that the
conversion of fuel-nitrogen to NOx occurred primar-
ily in the flamefront, was almost quantitative for
equivalence ratios from 0.6 to 1.0, and fell off outside
that range.E10t Fuel-sulfur was found to reduce the
formation of thermal NOx slightly and fuel-NOx sig-
nificantly,'111 a result which was in contrast with
prior observations for other types of burners.
Tang initially resisted my proposal to model the
post-flame reactions with a complete set of free-
radical mechanisms, but relented when I mentioned
that the alternative was explanation and possibly
reinterpretation of his experimental results by an-
other student. By trial-and-error he found that a
kinetic model incorporating twenty-one reversible
reactions was sufficient for the post-flame region for
the combustion of pure hexane, and that twenty-
three additional reactions were necessary for fuel-
nitrogen and sixteen more for fuel-sulfur. He postu-
lated a global model for the combustion of hexane to
CO and H2O. When the mole fraction of hexane fell
to 1 ppm due to combustion, the fuel-nitrogen and
fuel-sulfur were postulated to be converted quanti-
tatively and instantaneously to HCN and H2S re-
spectively. The post-flame model was then initiated.
The predictions of NOx by Tang were in good
agreement with his measurements for equivalence
ratios up to 1.1, but in disagreement beyond.[12' The
details of the computations revealed significant de-
viations of the concentrations of all of the free radi-
cals from their pseudo-steady-state values through-
out the post-flame zone, thus explaining the failure
of prior predictions. The model predicted negligible
formation of NO2 (less than 10 ppb) in contrast to a
significant fraction of the NO in the measurements.
Subsequent calculations suggested that all of the
measured NO2 was formed in the sampling tube,
Fall 1991

and this presumption has since been verified by
spectrographic measurements within a burner. The
deviation of the predicted concentrations of NOx for
very fuel-rich mixtures from the measured values
was presumed to be due to the failure of the postu-
late of quantitative conversion of the fuel to CO and
H20. This speculation was eventually confirmed as
described below. The predictions of NOx for hexane
with added fuel-nitrogen were in good agreement
with the measurements (except for very fuel-rich
mixtures for the same reason as above).J131 The pre-
dictions for added fuel-sulfur were in qualitative
agreement with the measurements, but the reduc-
tions in NO were less.""
The work of Tang reemphasized the generalities
noted above with respect to exploratory research.
The synergetic value of combined experimentation
and modeling was overwhelmingly apparent-par-
ticularly to Tang, who had initially resisted the in-
cremental effort required by the latter. Again, com-
mon wisdom, this time in terms of the pseudo-steady-
state postulate for the concentration of free radicals,
was found to be misleading. The detailed kinetic
model not only improved the predictions of NO. and
CO, but also explained the failure of the early mod-
els. The prediction of NO2 brought the process of
measurement into question, and subsequent model-
ing of the process of sampling demonstrated that the
measurements of NO2 and CO were indeed in error
due to an inadequate rate of quenching.
On the other hand, the extended range of experi-
ments with respect to equivalence ratio identified
the limit of validity of post-flame modeling alone,
and suggested a new direction for this research. The
qualitative agreement between the experimental and
the theoretical effects of fuel-sulfur on the formation
of NO. was essential in obtaining acceptance from
the reviewers of an article for publication, since this
result is contradictory to both experimental meas-
urements and theoretical predictions for other types
of combustion. On the other hand, the quantitative
discrepancy between the measured and predicted
effects of fuel-sulfur suggested an error in the mod-
eling which was examined and resolved in subse-
quent work. The results for fuel-sulfur suggest an-
other generality with respect to exploratory research.
One must be prepared to justify (in great detail and
beyond any question) radical results which invali-
date prior theories or generalities, particularly those
of the reviewers themselves.

Lisa D. Pfefferle proposed modeling chemical

kinetics in the preflame region as her doctoral re-
search. Since prior work had indicated the behavior
of the thermally stabilized burner to be essentially
fuel-independent, methane (for which the rate mecha-
nisms were presumed to be the simplest and most
reliable) was chosen as a fuel. This research ap-
peared in advance to be straightforward, but (as
indicated below) unexpected results and difficulties
arose at every turn. First, a clean and non-
oscillatory flame could not be stabilized in the new,
longer (508-mm) burner which had been cast. Sev-
eral weeks were spent recalibrating the metering
devices, analyzing the fuel, making a new 254-mm-
long burner, etc.-all to no avail. In despair, she
turned back to propane, which proved to burn stably
as before. She then tried ethane, which also burned
satisfactorily, and chose it in preference to propane
and methane for the subsequent studies.
Analysis of the data for methane revealed that
the steady rate of flow fell in the laminar regime
upstream from the flamefront as contrasted with the
turbulent regime for ethane, propane, and hexane.
She speculated (and later confirmed by modeling)
that this difference in behavior for methane was due
to the absence of a C-C bond. One productive conse-
quence of this adventure (which was very disturbing
at the time) was the construction of a graphical
correlation for the regimes of stability in the TSB for
various fuels, equivalence ratios, channel-diameters,
and channel-lengths. 41 Another was a computational
study of the adiabatic and non-adiabatic ignition of
various fuels and mixtures thereof.[15,161
The studies of stability confirmed that turbulent
flow is barely achieved in a 9.52-mm channel, even
with C2+ fuels. It may be inferred that turbulent flow
is unlikely to occur in ordinary chemical reactors
since the much lower rates of reaction compared to
those for combustion cannot be compensated for en-
tirely by a larger diameter. 171 Therefore, the postu-
late of plug flow cannot be justified on the basis of
turbulent flow in either homogeneous or heterogene-
ous reactors despite that implication in most text-
books on chemical reaction engineering.
The computational studies of ignition by
Pfefferle revealed that small concentrations of H2 or
C2+ in the mixture greatly enhance the ignitability.
Had ordinary natural gas been used (rather than
chemically pure methane) in her initial experimen-
tal studies in the thermally stabilized burner, the
difficulties which caused such agony and led to the
switch to ethane would not have been encountered.
On the other hand, the long-range effects of this
experience were many and all positive, including

another example of the fundamental difference be-
tween thermally stabilized combustion and other
processes, for which backmixing is a sufficient source
of free radicals for rupture of the C-H bond.
Having established a model for the preflame re-
gion, Pfefferle encountered great difficulty with the
stability of the solution of the set of differential
equations representing the kinetic behavior ahead
of the flamefront as contrasted with the single one
for global kinetics. This characteristic difficulty in
solving ordinary differential equations numerically
is known as "stiffness" and arises from widely sepa-
rated eigenvalues, or in physical terms in this in-
stance from the critical dependence of the kinetics
on minute concentrations of free radicals near the
inlet of the burner. Brute-force calculations require
intolerably small steps in space in that region.
Pfefferle surmounted this difficulty by using an ap-
proximate analytical solution for the very inlet, fol-
lowed by a standard scheme of marching.
Her computations revealed incredibly complex
behavior near the flamefront and resulted in very
good predictions of NO and CO even for very fuel-
rich mixtures. The path of oxidation of ethane to CO
and H20 was found to proceed through many inter-
mediates such as CH2OH.J181 This work confirms that,
while a global kinetic model with adjustable empiri-
cal constants is able to predict the thermal behavior
with reasonable accuracy, it cannot possibly be used
to predict the concentrations of CO, NO, etc., either
locally or overall. Pfefferle also modeled the pre-
flame as well as the post-flame zone for the combus-
tion of ethane with additions of ammonial'1 and of
ammonia and hydrogen sulfide.1201 The predictions of
NOx for pure ethane and for ethane plus ammonia
were in good agreement with her own measured
values, but the initial calculations for the added
effect of hydrogen sulfide were not. She concluded
that some important mechanisms were missing from
the best current compilations. She also concluded
that the greater reduction in fuel-NOx by fuel-sulfur
in the TSB as compared to conventional burners was
due to the higher temperatures in the immediate
preflame zone and to the minimal backmixing. The
contrasting chemical behavior for various conven-
tional burners was successfully modeled with the
same kinetic mechanisms by postulating an adjust-
able combination of a plug-flow reactor and a per-
fectly mixed one.
The productivity of Pfefferle's research was
greatly enhanced relative to original expectations by
the completely unexpected behavior of methane
vis-a-vis other fuels in the TSB. This result was a
Chemical Engineering Education

consequence of the fortuitous use of chemically pure
methane rather than natural gas. Many important
findings followed: 1) the absence of a C-C bond was
identified as the source of fuel-sensitivity; 2) the
absence of backmixing was identified as the source
of the difficulty in burning methane in the TSB as
contrasted with other burners; 3) the study ofignita-
bility revealed the sensitivity of the TSB to small
concentrations of C2+ and H2; and 4) the generalized
analysis of stability resulted in the recognition that
turbulent flow is unlikely in conventional reactors.
Other difficulties and anomalies were also a pre-
cursor to discovery. The stiffness of the free-radical,
preflame kinetic model as compared to a global one
resulted in the development of a new technique for
that purpose. The failure of the predictions of the
effect of fuel-sulfur on the formation of NOx to agree
with experimental measurements in the TSB identi-
fied missing mechanisms as the culprit, and the
different effects in a TSB and conventional burners
were rationalized in terms of a combination of plug-
flow and perfectly mixed reactors-a classical appli-
cation of the methodology of chemical reaction engi-

The study of stability by Pfefferle'14' led to a fur-
ther inference not mentioned above. Since the stable
flow upstream from the flamefront is barely turbu-
lent, at least for a 9.52-mm channel, the approxi-
mately seven-fold increase in absolute temperature
and the associated approximately five-fold increase
in dynamic viscosity result in a decrease of the Rey-
nolds number behind the flamefront to much less
than 2100 for all conditions. Laminarization was
therefore to be expected. In all of the above-
mentioned modeling, plug flow was postulated both
upstream and downstream from the flamefront, ex-
cept for the evaluation of the heat-transfer coeffi-
cient for convection, which was estimated from em-
pirical correlations for fully developed turbulent flow
upstream and for developing laminar flow down-
stream. The postulate of plug flow in the kinetic
model was excused on the basis of the demonstra-
tion by ArisE21' that the error in the conversion of a
reactant due to the postulate of plug flow rather
than laminar (parabolic) flow is less than 11% for a
first-order reaction and even less for higher orders.
Even so, I was very pleased when Lance R. Collins
chose as his doctoral research to investigate lami-
narization behind the flamefront and its effect on
the post-flame reactions. He computed the time-
averaged field of velocity using a low-Reynolds-

radical kinetic model.'231 His measured pressure gra-
dients and velocities at the centerline were in rea-
sonable accord with the predictions, but both his
measured and predicted concentrations of CO were
as much as 25% higher than computed values based
on plug flow. This unexpected result led to the reali-
zation that the generalization of Aris is not appli-
cable to the residual concentration of a reactant. For
example, the possible error in the residual concen-
trations of a reactant by a first-order reaction due to
assuming plug flow rather than laminar flow is un-
bounded. The formation of NOx is not affected sig-
nificantly since it is effectively zero-order and as
such is independent of the velocity distribution.
The lesson here is that an authoritative gener-
alization, although valid per se, may not be valid for
conditions that differ subtly. We were ourselves
misled for over a decade by the accuracy of the pre-
dictions of NO to the extent of presuming a
chemical-kinetic rather than a fluid-mechanical ex-
planation for the observed errors in the predictions
of CO. It is noteworthy that none of the reviewers of
our several papers seriously challenged the applica-
bility of the postulate of plug flow in our modeling.

The very low concentrations of NOx produced in
the thermally stabilized combustor are, as noted
above, somewhat at the expense of large residual
concentrations of CO. Furthermore, NO continues
to form in the products of combustion after leaving
the burner insofar as they remain at high tempera-
ture. This period may be significant with conven-
tional boilers, etc. As his doctoral research, Mark R.
Stronger chose to investigate a process devised to
quench the formation of NO in the boiler, but to
allow continued oxidation of CO while generating
steam. The equipment consisted of seven metal tubes
(contiguous with the channels of the combustor) that
passed through a pool of boiling water contained in a
cylindrical jacket.
The process worked exactly as planned chemi-
cally124J but the heat transfer coefficient for forced
convection from the products of combustion was much
higher than expected.'251 A theoretical solution for
the fluid mechanics and heat transfer using the same
k-e model as that of Collins provided an explana-
tion.126' The flow inside the combustor is in transi-
tion from turbulent to laminar flow. As the gas is
cooled inside the metal tubes, the viscosity decreases,

the Reynolds number increases, and a transition
back to turbulent flow occurs. Owing to this transi-
tion, a heat transfer coefficient higher than that for
either fully developed laminar or fully developed
turbulent flow is achieved.
The turbulent-laminar transition explains, at
least in part, the excessive heat transfer coefficients
required in the models of Chen[41 and Choi.'81 The
heat transfer coefficient for forced convection inside
small tubes is much greater than that for radiative
transfer and unconfined convection in conventional
boilers, even without enhancement by transition.
The combined effect produces a reduction of several
orders of magnitude in the size of the boiler.
Although the chemical behavior in Strenger's
research was much as expected, the thermal/fluid-
mechanical behavior produced a favorable surprise
which could be explained only through the theoreti-
cal modeling.

Combustion is a worthy subject of research by
chemical engineers. It is of obvious practical impor-
tance, but has been the subject of only limited funda-
mental work. As a result of recent progress in chemi-
cal kinetics and machine computation, it is respon-
sive to modeling with the classical techniques of
chemical reaction engineering, and as a result of
recent improvements in instrumental techniques,
the in situ measurements necessary to test critically
such modeling have become possible.
Thermally stabilized combustion proved, as indi-
cated herein, to be a fortunate choice for this pro-
gram of research because the fluid mechanics are
simple relative to all conventional processes of com-
bustion, while the thermal/chemical behavior differs
radically in almost every respect. The characteris-
tics of thermally stabilized combustion, which are
noted herein only in a historical context, are sum-
marized elsewhere.[27]
Conclusions relative to the conduct of academic
exploratory research were drawn above in connec-
tion with each of the separate undertakings, and
only generalities in this regard will be listed here.
Most discoveries arise from experimentally observed
anomalies (the existence of multiple stationary states
was an exception in that it arose from modeling).
Theoretical modeling is usually necessary to
understand and explain observed anomalies, and
thereby to determine whether they represent physical
behavior or experimental error.
The combination of experimentation and modeling is
generally more productive than their separate

Consecutive individual efforts on a general problem
often provide new insights.
It follows that one of the most important roles of
a faculty advisor is to encourage students to be on
the alert for anomalies and to pursue and/or resolve
them. A more difficult but worthwhile endeavor is to
persuade theoretically inclined students to test their
modeling experimentally, and experimentally in-
clined students to develop a model to explain and
extend their measurements.

dard enthalpy change for reactions as a function of
temperature. Further, the units are now essentially
all SI. There has been some rearrangement of mate-
rial that includes putting fugacity earlier and devot-
ing more material to EOS and high-pressure phase
equilibria. Finally, there are revised examples and
Over the years we have used different editions of
the text in our own teaching. A recent experience
was with students whose first course was in the
engineering core, so this book was used for a subse-
quent chemical engineering course in chemical th-
ermodynamics. Our opinions on the success of the
book are similar. In general, the examples and prob-
lems are very good-they are challenging but consis-
tent with the text. The exposure to all combinations
of phase equilibria is highly desirable. Also, the pro-
grams included in the second edition can be quite
useful to students in addressing real (and therefore
complex) systems, as well as fostering an explora-

tory mode of how nature actually behaves. This is
especially valuable for students who must encounter
the idealized or limited nonideal descriptions of physi-
cal chemistry thermodynamics.
The connections of the text to other courses is
difficult to measure. Our experience is that differ-
ences of approach and notation usually overwhelm
the similarities that may appear to students in later
courses unless the same instructor is involved.
The text does achieve a significant level of detail,
but this often leads to confusion about the funda-
mentals. The dilemma of how many formulae to put
into the hands of students is solved by using exten-
sive tables of equations for different cases. Often,
the student's reaction is to try to use these tables to
look up a formula rather than to quickly derive the
one they need for a problem. Another effect of this is
to inadequately distinguish between fundamental
concepts, approximate relationships, and specific il-
lustrations. The result is that students become un-
sure of which are the big things that should be
focused on and remembered. It also leads to a great
deal of the material being strictly mathematical,
with little physical connections that are either macro-
scopic or molecular.
Teachers will undoubtedly have differences with
the author about his selection of correlations-that
is inevitable in this area. In any case, the correla-
tions are often presented without indication of
whether they are to be used in real work or whether
they are merely illustrative. The corresponding states
treatment involves graphs from Hougan, Watson,
and Ragatz containing Zc, but equations containing
the acentric factor. While the treatment for mix-
tures is complete, it is quite mathematical and fol-
lows a considerable discussion of the fugacity of pure
components, so the whole exposition appears less
focused than it might be.
All of the above issues may be dealt with by an
experienced instructor who is comfortable with this
difficult subject. In particular, highlighting the im-
portant material and simplifying complexities will
be necessary. This takes a high level of concentra-
tion and a willingness to sacrifice some of the rigor
of the text-this might ask for more commitment
from students than they want to give. They will also
have to deal with the text and the teacher appearing
to conflict with one another.
The qualities of the text are numerous. It has
been adopted in a limited number of situations, ac-
cording to the latest AIChE Education Survey, and
it is worthy of serious consideration at least as a
reference. O

ill and Perry are senior engineering students.
They met at their freshman orientation seminar,
started dating soon afterward, and have been to-
gether ever since. A friend once remarked that they
had the only perfect relationship he had ever seen:
there wasn't a single thing they agreed about!
They had an appointment to meet in the student
lounge at 3:00 this afternoon. It is now well past
4:00. Jill is sitting at a table alone, trying to work
but frequently looking over at the door and scowling.
Perry finally walks in, greets a few friends, walks
over to Jill's table, and sits down.

Perry: (brightly) "Hi-get it all figured out yet?"
Jill: (glaring) "Where were you?"
Perry: "Oh, a few of us in Tau Beta Pi got going
on the plans for the Awards Banquet and I
lost track of the time...I'm not that late, am

an hour and twenty minutes might qualify
for that late. Am I wrong or did we agree
Sunday that we'd study for the design test
from 3 to 4 today?"
Perry: "Come on, lighten up. We still have a couple
of hours till supper, and the exam's not
until Friday-you know Professor Furze
postponed it yesterday."
Jill: "I know he did, but we still had an
appointment...and I've got a 331 lab report

Jill is ajudger and Perry is a perceiver.* Judg-
ers tend to be organized and decisive: they like to set
and keep agendas and reach closure on issues. Per-
ceivers tend to be spontaneous, flexible, and open-
minded; they like to keep their options open as long
as possible and postpone decision-making until they
feel sure they have all the relevant information.
Judgers plan ahead for most things. As students
they budget their time for homework and study so
they don't have to do it all at the last minute, and
they can usually be relied on to turn in assignments
on time. However, they tend to jump to conclusions,
make decisions prematurely, and doggedly adhere to
agendas that may no longer be appropriate. In their
classes, judging students want clearly defined ex-
pectations, assignments, and grading criteria, and
they don't like rambling lectures or class discussions
that seem to have little point.
Perceivers do as little planning as possible,
preferring to remain flexible in case something

The degree to which one favors one or the other of these types
can be determined with the Myers-Briggs Type Indicator, a per-
sonality inventory based on Jung's theory of psychological types
that has been administered to over one million people including
many engineering students and professors.11'21 Jill and Perry
are illustrative of the two types, but not all judgers are just like
Jill and not all perceivers are just like Perry. The two catego-
ries represent preferences, not mutually exclusive categories:
the preferences may be strong or weak, and all people exhibit
characteristics of both types to different degrees.

better comes up. They tend to work in fits and
starts, alternating between periods of unfocused ac-
tivity and frantic races to meet deadlines. They have
trouble sticking to agendas, tend to start many more
projects at one time than they can possibly finish,
and are often in danger of missing assignments and
doing poorly on tests due to insufficient study time.
However, they are more likely than judgers to be
aware of facts or data that don't fit their mental
picture of a situation and in fact may go out of their
way to look for such contradictions. When they don't
fully understand something they tend to keep it
open, gathering more information or simply waiting
for inspiration to strike rather than accepting the
first plausible explanation that occurs. Their flexi-
bility and tolerance of ambiguity will make some of
them superb researchers.
While students of both types may become excel-
lent engineers and managers, the working habits of
strong perceivers may make getting through school
a major challenge for them, and anything that can
be done to help them survive is worth attempting.
They benefit from opportunities to follow their curi-
osity and work best on tasks that they have chosen
themselves. They are not helped much by advice to
work at a steady pace and not leave things for the
last moment, which may be too radical a departure
from their natural style to be manageable; however,
it might help to ask them to figure out how late they
can start to work on the assignment or study for the
test and still do everything else they have to do.
Perceivers rarely look at the holes they are digging
themselves into through lack of planning. If they can
be persuaded to itemize the things they intend to do,
they might be convinced that without some planning
they don't have a prayer of doing the things they
have to do.
Epilogue: Ten years later

Jill and Perry got married shortly after gradu-
ation, managing (barely) to survive Perry's twenty-
minute late arrival at the church and Jill's insis-
tence on laying out an hour-by-hour schedule for
their honeymoon. Jill got a job in a design and con-
struction firm, eventually became a highly success-
ful project manager, and is now in line for a vice-
presidency. Perry went on to graduate school, got a
PhD, and is now an eminent researcher at a national
laboratory. It took years, but they finally figured out
a good way to get along with each other.* 0

Since Bhopal, words such as hazard, risk, waste,
and chemical seem to be synonymous to the pub-
lic and the media. There is increasing public, gov-
ernment, and industry awareness and concern over
a number of problems: hazardous and toxic chemi-
cals in the workplace, the environment, and home;
increasing quantities of waste and costs of disposal,
along with limited treatment capacity; industrial
and transportation spills and accidents involving
chemicals; contamination of water supplies; etc.
These concerns are being manifested by more
(and tighter) local, state, and federal regulations. At
the same time there is public opposition to things
such as siting of incinerators, landfills, and indus-
trial operations involving hazardous materials.
In response to the problem, the US Environmental
Protection Agency created the phrase Risk Reduc-
tion Engineering as part of a multimedia-based "Pol-
lution Prevention" program. The goal is to minimize
wastes that present current and future risks to
human health and the environment.
With regard to chemical engineering, the risk
reduction concept encompasses a broader spectrum
which includes safety, health, and loss prevention,
as well as waste management and environmental
controls. Risk reduction also deals with the techno-
logical/societal interface in the sense that manage-
ment, regulations, and public relations are all com-
All of these concepts are implicit in chemical en-
gineering education. However, despite the apparent
job opportunities for chemical engineers in, for ex-
ample, environmental engineering, risk reduction
still seems to be largely ignored in the curriculum.
In particular, chemical engineering will play a
Copyright ChE Division, ASEE 1991

major role in risk reduction by developing, assess-
ing, and applying the technology that will predict,
measure, control, and reduce risks from hazardous
materials. It is thus timely (and perhaps manda-
tory) that, in the chemical engineering curriculum,
greater emphasis be placed on topics such as waste
reduction, safety, and health. While it is not neces-
sary to make experts of all the students, the under-
graduate program is a logical place to begin provid-
ing a background for recognition of potential haz-
ards and an awareness of safe and clean process and
product designs. Risk reduction can be addressed in
most chemical engineering courses, from general
chemistry to plant design, and the concepts should
be easily understood by the students.'"
I do not believe that new engineering programs
in safety and health or waste-reduction engineering
are needed, such as those that exist, for example, in
environmental engineering. Much of the relevant
knowledge and tools are implicit in the existing
chemical engineering curricula. However, concepts
such as hazardous materials, engineering controls,
and materials substitution, are not usually covered,
and could, at the least, be presented through ex-
ample and homework problems such as those avail-
able from the AIChE Center for Chemical Process
Risk reduction can be viewed as a unifying gen-
eral concept that will provide an awareness, sensi-
tivity, knowledge, and positive attitude for the stu-
dents' future stewardship of health, safety, and the

environment. Inclusion of these areas in the curricu-
lum could be facilitated without adding numerous
courses by incorporating them in the "Risk Reduc-
tion" spectrum. For example, in the materials and
energy balances course, the properties, effects, and
management of hazardous materials can be presented
from the viewpoint of simultaneous concerns in the
workplace, home, and environment.
In this paper, inclusion of risk reduction in the
curriculum will be explored, and current related
teaching efforts at the University of Louisville will
be described. General principles and commonalities,
synergies, and trade-offs between the components
will be emphasized.

Several ideas for including safety and health in
the chemical engineering curriculum have been pre-
viously presented.",' These ideas can also be put
into the general framework of risk reduction since
many of them also pertain to environmental con-
cerns. At the University of Louisville, risk reduction
was incorporated into the material and energy bal-
ances course when I last taught it. A one-hour course
entitled Safety, Health, and Environment," will be
mandatory for juniors in the spring 1991 term, and a
two-course sequence, "Safety and Health" and "In-
dustrial Waste Management," was developed as first-
year graduate (500-level) electives. (These two
courses would also be suitable as senior electives,
but our seniors do not have electives.) Graduate
students can also take elective courses in "Mem-
brane Separations" and "Chemodynamics," which are
both related to risk reduction. Graduate students at
the University of Louisville include our fifth-year
Master of Engineering (M.Eng.) students.
A common feature in the material and energy
balances, safety and health, and industrial waste
management courses is a segment we call "In the
News." During the first five minutes of class, articles
from the local newspaper, Time magazine, Chemical
& Engineering News, etc., which are related to ei-
ther chemical safety and health or environmental is-
sues are discussed. Since Louisville is a highly-
industrialized city there is always some local or state
news that the students can relate to, and this height-
ens their interest in the courses. In my opinion, the
day-to-day real-world relevance of these courses is
an important feature. In contrast to more traditional
courses, students asked many questions. It is per-
haps not so surprising to find that students are
interested in risk reduction and that many have cho-

Sophomore students interview for their first co-
operative internship position while taking the mate-
rial and energy balances course, and the M.Eng.
students are interviewing for permanent positions
at the same time. Both groups asked the interview-
ers about the company's health, safety, and environ-
mental practices and opportunities. Feedback from
the interviewers indicated that this helped to create
a positive impression of our students. After their
first co-op position, many of the sophomore students
reported that they had dealt with risk reduction ma-
terial covered in the material and energy balances
course, e.g., materials safety data sheets, oxygen
demand of waste-waters.
Specifically, some of the teaching modules from
the AIChE Center for Chemical Process Safety12' were
used in the material and energy balances course.
The students were also required to fill out a materi-
als safety data sheet. Next time I teach the course,
problems developed from waste minimization assess-
ments will be incorporated into the course, e.g., re-
covery of nickel salts from electroplating rinse-

"Safety and Health" and "Industrial Waste Man-
agement" are broad-based survey courses offered at
the first-year graduate level in the fall and spring
semesters, respectively. We attempt to describe these
courses in a manner that emphasizes generic and
common features. Some of the risk reduction con-
cepts can be covered in either course or in both.
The course outlines by topic are shown in Table
1, and the textbooks used are listed in Table 2. The
same generic topics are covered in both courses,
including regulations and standards, properties, ef-
fects and characteristics of hazardous and toxic ma-
terials, modeling, heirarchy of management and con-
trol options preventive measures such as substitu-
tion and inventory control, control technology, and
risk assessment. By necessity, there is some overlap
of specifics between the two courses, even though

repetition is minimized. For example, SARA Title III
is discussed in both courses. However, OSHA regu-
lations are discussed primarily in Safety and Health,
and RCRA primarily in Industrial Waste Manage-
ment. Threshold limit values, while referred to in
Industrial Waste Management, is covered in depth
in the safety and health course, while hazardous
waste lists are discussed in Industrial Waste Man-
agement. Hazardous waste characteristics are dis-
cussed in both courses, but with different emphasis.
However, in each course the commonalities and rela-
tionships between the different aspects of risk re-
duction are pointed out.

Both courses include student team audits and
inspections. In Safety and Health, safety and health
inspections of the chemical engineering laboratories
were done, while in Industrial Waste Management
the students did a waste minimization assessment
at a local plant. The students found the inspections
to be eye-opening, interesting, educational, and fun.
Either of these courses is suitable for seniors, and to
help meet accreditation guidelines they can easily be
structured to include design and to enhance student
communication skills. As an aside, student partici-
pation in safety, health, and waste reduction assess-
ments is an excellent teaching tool. Several students

are participating in a funded waste minimization
assessment program and are involved with the prepa-
ration of preliminary engineering feasibility studies
for a variety of different manufacturing facilities.
Two of these students have received job offers from
major companies to work in waste reduction after

In general, the courses are more descriptive and
qualitative than quantitative and theoretical, al-
though a limited number of theoretical/calculational
problems are assigned. Safety and Health is the
more technical course, primarily because of the re-
cent availability of a new chemical engineering text-
book.141 However, the students are made aware of the
relevant principles and techniques from traditional
courses and how to apply them. For example, mate-
rial from Transport Phenomenat51 is used to estimate
relative evaporation rates of solvents as a measure
of fire and health hazards and to estimate solvent
loss. With regard to risk reduction, the students
already know much of the necessary technical con-
tent, but need to be shown where and how to use it.
In this sense, the instructor serves as more of a
facilitator than a subject-matter expert.

Since safety, health, waste management, etc.,
cover such a wide range of topics, it would be diffi-
cult for any one instructor to have sufficient overall
expertise. Also, the available textbooks in these sub-
jects do not cover many relevant topics. Therefore,
quest speakers are used to lecture in areas that they
work in, such as waste-water treatment, air-pollu-
tion control, and toxicology. The part-time students

dents, and they particularly appreciated the net-
working aspect, as did I.

Many useful movies and video tapes are avail-
able in safety, health, and environmental areas, and
they are also used in class (see Table 5). The videos,
many of which are excellent dramatizations, often
depict things much better than the instructor or a
text can. Study guides for the videos, in the form of
assigned questions, are given to the students. Be-
cause of the deficiencies within the textbooks and
the lack of breadth and currency of the topics, nu-
merous additional materials are also given to the
students (see Table 6).


The primary prerequisite for Safety and Health
and Industrial Waste Management is a BS in sci-
ence, math, engineering, or its equivalent. Thus, the
courses are taken by first-year graduate and M.Eng
students from other departments, along with part-
time students from industry, consulting firms, and
government agencies. Many part-time students come
from as far as sixty miles away.

The courses are offered on a one night per week
basis, 2-hours 45-minutes per class, so as to attract
part-time students. Announcements of the courses
are placed in newsletters of various regional and
statewide professional organizations such as the Ken-
tucky Waste Reduction Centers and the Air and
Waste Management Association.

The first offering of Industrial Waste Manage-
ment drew about thirty-five students, two-thirds of
which were part-time students. Several of the part-
time students also took Safety and Health which
was taught the following year with fifteen students
(nine of them part-time). In the second offering, In-
dustrial Waste Management had eighteen students
(fourteen of them part-time) and Safety and Health
had ten students (nine of them part-time). These
courses are being recommended to co-workers, and
the part-time students have requested additional
courses in risk reduction. In response, we plan to
offer a course entitled Waste Reduction, Treatment,
and Disposal in the future.

Many of the part-time students are not pursuing
a degree and thus can register through Continuing
Studies rather than through the usual, more tedi-
ous, routes. Students not applying the credits to-
wards a degree, along with non-chemical engineer-
ing students (who may lack some of the technical

background), can take the course on a pass/fail or
audit basis to minimize the pressure of grades. The
courses are taught on an informal, relaxed basis
(similar to a workshop or seminar) which enhanced
the students' enjoyment. For example, on some nights
when movies or video tapes were being shown, pop-
corn was served. Because of the maturity of the
students, it was a pleasure to be on a more collegial
basis with them, and as pointed out earlier, the part-
time students are an excellent classroom and net-
working resource.

Some examples of the unifying concepts of risk
reduction, resultant synergies, and trade-offs are
briefly explored. These approaches can be used in
either of the two survey courses or as a component of
any appropriate required course.

One example of synergy is in finishing operations
such as paint and coating applications. The same

properties that make wastes and emissions from
these operations hazardous also contribute to expo-
sure that endangers employee health and plant
safety. Thus, waste reduction measures will simul-
taneously benefit employee safety and health, and
vice versa. These measures include substitute mate-
rials and alternative methods, such as aqueous-based
rather than solvent-based paints, powder coatings,
and airless or electrostatic spray guns. Another syn-
ergy that occurs with waste reduction is conserva-
tion of raw materials. For example, increased recy-
cling of plastics can simultaneously reduce depend-
ence on foreign crude oil.

Trade-offs or conflicts can also be shown (for ex-
ample) between waste minimization and quality
management, and between safety and waste disposi-
tion considerations. Reworking of off-specification
and waste solids from tank cleaning into useful prod-
ucts is a waste minimization technique. Spills on the
one hand must be properly retained and disposed of
so as not to damage the environment. On the other
hand, a reactive (but improper) response to a haz-
ardous materials spill might be to flush it immedi-
ately down the drain.


Some preliminary ideas concerning the inclusion
of the risk reduction spectrum into the curriculum
have been presented and exemplified in this paper.
Because of the increasing importance of risk reduc-
tion to chemical engineers, further exploration of
ways to incorporate these concepts seems manda-
tory. Availability of teaching materials such as the
problem sets available from the AIChE Center for
Chemical Process Safety can facilitate this process.
Hopefully, such materials will be available from the
newly-established AIChE Center for Waste Reduc-
tion Technology.

T he United States aerospace, automotive, bio-
materials, chemical, electronics, energy, met-
als, and telecommunications industries collectively
employ more than 7 million people in materials sci-
ence and engineering and have sales in excess of
$1.4 trillion. Recent reports'11 have called the 1990s
the "Age of Materials" and have concluded that the
field of materials science and engineering is enter-
ing a period of unprecedented intellectual chal-
lenge and productivity. Chemical engineers, with
their background in reaction engineering and trans-
port processes, have the skills necessary to make
significant contributions in this area.
A strong component of materials science and en-
gineering is ceramics science and engineering. Al-
though many applications of ceramics have in the
past been low-tech, a vast number of new high-tech
ceramics have been developed in recent years, open-
ing up a large number of new and exciting applica-
tions for a wide variety of industries. Ceramic super-
conductors may provide new methods of energy trans-
mission and new types of electronic devices. Elec-
tronic ceramics such as BaTiO3 and SrTiO3 are used
to make capacitors and sensors. Ferroelectric ceram-

ics can be used to produce memories for computers.
A variety of metal oxides, nitrides and silicides are
used in computer chips and to make substrates for
the chips themselves.
Ceramics can also be used to make chemical sen-
sors for detecting small amounts of hazardous sub-
stances for applications in hazardous waste control.
They are also used as catalysts for chemical reac-
tions or as catalyst supports in the chemical indus-
try. These and other applications have led to a tre-
mendous interest in the synthesis, processing, and
characterization of ceramic materials in the form of
powders and films.
The chemical engineering department at the
University of New Mexico dramatically expanded its
program in ceramics science and engineering follow-
ing the establishment of a National Science Founda-
tion-supported UNM/NSF Center For Micro-Engi-
neered Ceramics (CMEC). Numerous research proj-
ects, many in the areas mentioned above, are now
available to interested students. These opportuni-
ties are particularly interesting since demand is high
for students with a background in ceramics, with
fewer than forty PhDs being granted in the United
States each year in Ceramics Science and Engineer-
ing (with roughly half of them going to foreign stu-

Sol-gel processing (see Figure 1) refers to the
room temperature formation of inorganic materials
from molecular precursors.121 Inorganic salts or metal
organic compounds dissolved in aqueous or organic
solvents are hydrolyzed and condensed to form poly-
mers composed of M-O-M bonds. These polymers
may be deposited on substrates to form thin films,
drawn into fibers, or cast in molds and dried to form
"near-net-shape solids." Prior to drying, the struc-
tures of the polymers are often described by fractal
geometry,131 a consequence of kinetically-limited
growth mechanisms such as reaction-limited cluster
aggregation.[4' The properties of fractal objects may
be exploited to prepare materials (films, fibers,
or bulk) with precisely controlled pore structures
(e.g., pore size, surface area, and percent porosity).
Films with controlled pore sizes151 may be used as
molecular sieves to impart steric selectivity to sen-
sor devices or to separate a mixture of gases on the
basis of size.

The inherent porosity of sol-gel-derived materi-
als provides access to reagents throughout the mate-
rial's interior. Surfaces may be modified by reactions
with gas or liquid reagents, and secondary phases
may be depositied within the pores to form nano-

scale composite materials.j6' Alternatively, secondary
phases may be incorporated in the liquid or sol.
Under certain conditions, deposition of the diphasic
sol results in a composite film in which the second
phase is embedded in a dense gel matrix. Zeolite/gel
composites made by this procedure can impart mo-
lecular recognition capabilities to sensor surfaces.j71

Sol-gel-derived materials are highly metastable;
their structures are dictated by kinetics rather than
by thermodynamics.E2' Kinetic pathways may be ex-
ploited to prepare novel inorganic materials. Only
when these materials are processed in the vicinity of
the glass transformation temperature do their struc-
tures approach those of their conventionally pre-
pared counterparts.'81

Abhaya Datye is interested in: heterogeneous
catalysis and surface science; structure and proper-
ties of thin films and interfaces in ceramics and
semiconductors; and materials characterization by
electron microscopy.

Phenomena occurring at the interfaces between
dissimilar materials have enormous implications in
materials we use every day. For instance, the strength
of the bond between a metal and a ceramic deter-
mines the properties of glass metal seals as well as
the high-temperature stability of heterogeneous cata-
lysts. Sometimes a weaker interface is desired (as in



a fiber-reinforced composite) to redistribute stresses
at the interface and deflect cracks to make a brittle
ceramic tougher. In semiconductors the performance
of a device is often determined by the impurities and
defects at an interface. Therefore, engineering of
such complex materials requires a good understand-
ing of the interface region and the means of tailoring
the interface to achieve desired properties. Since
even a monolayer of a hydrocarbon can affect the
wetting of water on a solid substrate, it is apparent
that interfacial properties are determined by changes
occurring over the scale of atomic dimensions. It is
therefore necessary to use probes having high spa-
tial resolution as well as those that give chemical
information from the near-surface region. In the re-
search at the University of New Mexico, high-resolu-
tion transmission electron microscopy and surface-
sensitive spectroscopies are used to study these
materials and correlate their structure with proper-
ties relevant to their commercial applications.

One project involves the study of thin-film coat-
ings of non-oxide ceramics and their interactions
with ceramic substrates.193 We are examining the
potential of boron nitride for use as a high-tempera-
ture coating material for fiber-reinforced compos-
ites. The interaction of BN with ox-
ide ceramics is quite strong, and BN .7
appears to readily wet and coat these
substrates. However, a detailed
study101' of the atomic structure of
this interface reveals that the inter-
atomic spacing between the BN
sheets and MgO is larger than dis-
tances normally associated with
chemical bonding (see Figure 2).

Toivo Kodas is studying: the formation and proc-
essing of electronic, mechanical, and superconducting
ceramic powders; laser-processing of materials;
chemical vapor deposition of ceramics and metals for
microelectronics applications; and aerosol physics
and chemistry.
High-purity powders with controlled chemical
compositions, particle size distributions, and micro-
structures are required as precursors for fabrication
of superconducting and conventional ceramic parts.
The goal of this work is to develop gas-phase routes
for the formation of powders with these characteris-
tics. Both gas-to-particle conversion and intrapar-
ticle reaction processes are being examined. Research
is focused on obtaining a basic understanding of the
physical and chemical processes controlling multi-
component powder production by chemical reaction,
and processing these powders to produce ceramics
with unique electrical, optical, and mechanical prop-
erties. Examples include Ag/YBa2Cu3O7x[16-181 for a
variety of applications, Ba1-xCaxTiO3 for tempera-
ture sensors'191 (see Figure 3), mullite for electronic

industry for the formation of thin films of a wide
variety of materials. This process begins with a vola-
tile molecular species that is transported to a sub-
strate where it decomposes and results in deposition
of material with desorption of volatile byproducts.
The chemistry occurring during deposition deter-
mines the deposition rate, minimum deposition tem-
perature, adhesion to the substrate, and electronic
properties. Yet the chemistry occurring during most
CVD processes is poorly understood. Our research
involves the use of high pressure and ultrahigh vac-
uum systems utilizing mass spectrometry, Auger
electron spectroscopy, temperature-programmed
desorption, FTIR, and Raman spectroscopy to study
the surface and gas phase chemistry. The goal is to
develop a better understanding of the role of chemis-
try in determining the properties of the deposited
material. Current projects are the examination of
deposition of PLZT with Radiant Technology, Cu
with Motorola,[22' and YBa2Cu 30x with Los Alamos
National Laboratories.
Aerosols (fine particles suspended in a gas) play
a fundamental role in fine metallic and ceramic par-
ticle production, optical fiber production, thin film
formation, and contamination control in cleanrooms.
We are currently examining the interaction between

Douglas Smith is currently examining charac-
terization of porous materials, transport phenomena
in porous media, sol-gel, and powder processing.
The pore structure of materials is of considerable
interest for a large number of applications which in-
clude ceramics processing, catalysis, membrane sepa-
rations, radioactive waste isolation, and coal gasifi-
cation. The basic approach is to study the physics of
both established and innovative pore structure analy-
sis tools in an attempt to extract more detailed infor-
mation about porous solid systems.
Conventional techniques for pore structure analy-
sis include mercury porosimetry, nitrogen adsorp-
tion/condensation, and microscopy (optical, scanning,
and transmission electron). Each of these techniques
suffers from different disadvantages which limit ac-
curacy and preclude their use for in-situ pore struc-
ture analysis. Therefore, considerable incentive ex-
ists for the development of new techniques for pore
structure analysis. Professor Smith's laboratory has
pioneered the development of low-field, NMR spin-
lattice relaxation measurements of fluid contained
in pores as a structure analysis technique. This ap-
proach allows the study of pores of "wet" materials
and allows imaging of pore structure as a function of
time while the structure evolves.
In addition to pore structure analysis, the study
of the physical nature of surfaces is of interest. In
particular, the fractal nature of surfaces is being
studied via molecular probe techniques.[261 A parallel
effort using SAXS (small angle x-ray scattering) and
SANS (small angle neutron scattering) is underway
in collaboration with investigators at Sandia Na-
tional Laboratories. The growth of fine particles and
polymers in solution is studied via both SAXS and
light scattering.
Using expertise in pore structure analysis, a num-
ber of ceramics processing problems are being exam-
ined. These include pore structure evolution and
elimination during sintering of ceramic green bod-
ies, dispersion of powder agglomerates, packing of
powders during green body formation,[271 and pore
structure development during sol-gel processing of
xerogels and aerogels (both bulk[21,29') and coat-
ings.[30,31' Ceramic powder synthesis is conducted us-
ing a range of techniques including reactive laser

Much of the research in ceramics science and
engineering is being carried out in the National Sci-
ence Foundation Center for Micro-Engineered Ce-
ramics, which is housed in the chemical engineering
department. The Center consists of fifteen profes-
sors from the University of New Mexico (seven from
chemical engineering, four from chemistry, one each
from mechanical engineering, physics, and geology),
over ten staff members from Sandia National Labo-
ratory, and over ten staff members from Los Alamos
National Laboratory. A critical feature of the Center
is the membership of more than fifteen industrial
members. This allows the Center to combine the
expertise of the national labs, the university, and
industry to attack ceramics-related problems of
interest to industry. The goals are to attack use-
ful problems, to transfer technology between indus-
try, the National Labs and the University, and to
train students in ceramics science and engineering.
A key feature of the Center is the hands-on policy for
use of equipment. The Center is equipped with a
variety of state-of-the-science equipment, shown in
Table 1.


Another feature of the CMEC and the chemical
engineering department is the extensive interactions
with other departments at the university. The proj-
ects in the CMEC are interdisciplinary with faculty
from chemical engineering, chemistry, physics, geol-
ogy, mechanical engineering, and the national labo-
ratories involved in each project. In addition, signifi-
cant interactions occur with the Center for High
Technology Materials in electrical engineering whose
strength is optoelectronic materials.

The extensive interactions of the chemical engi-
neering department and CMEC with the national
laboratories has numerous advantages. The strengths

T he course "An Introduction to Molecular Trans-
port Phenomena" is intended for upper-level
undergraduates or first-year graduate students in
engineering and science. The overall goal of the course
is to provide a comprehensive description of the mo-
lecular basis of transport phenomena for students
who have no previous background in statistical me-
chanics or statistical physics.
It is clear that recent dramatic advances in com-
putational abilities (e.g., supercomputers and con-
nection machines"1) and in atomic-level experimen-
tation (e.g., atomic force microscopy and scanning
tunneling microscopy121) require that undergraduate
engineers obtain a better molecular understanding
or interpretation of engineering processes. One ex-
ample is a surge in supercomputer purchases in the
chemical industry; an example of the benefits of
supercomputer computations is a reported $1-2 mil-
lion savings in development costs for a new catalytic
process."31 By studying the thermodynamic proper-
ties of the system through use of molecular simula-
tions on a supercomputer, some critically unusual
properties were discovered that would have been
difficult to detect through physical experiments.
These new computational and experimental ca-
pabilities make it possible to examine, design, and/
or enhance systems and processes beginning at a
molecular level description-an approach that may
be called "molecular engineering." In general, mo-
lecular engineering represents a new and powerful
method of analysis where a rational and scientific
framework can be utilized for the systematic study
of highly complex engineering systems.
Michael H. Peters is Associate Professor and Chair
in the Department of Chemical Engineering at the

Faculty Associate with the Supercomputer Computa-
tions Research Institute at Florida State University.
He received his BS from the University of Dayton in
1977 and his PhD from the Ohio State University in
1981. His research interests are in the areas of macro-
molecular and colloidal phenomena, Brownian motion
theories, and molecular transport phenomena.

Molecular engineering also plays a critical role in
the development of newly emerging areas of chemi-
cal engineering (such as advanced polymeric and ce-
ramic materials, and biochemical and biomedical
engineering) where a molecular and macromolecu-
lar description is a necessity rather than just an
alternate method of analysis.[4] There is a current
need in the undergraduate curriculum for both quali-
tative and quantitative descriptions of processes and
phenomena involving gases, liquids, and solids from
a molecular viewpoint.
In this course, the macroscopic treatment of trans-
port phenomena learned in previous courses is de-
veloped from molecular-level descriptions of matter.
It is shown that the ad-hoc assumptions made in
previous transport phenomena courses can be re-
placed by rational and scientific methods that will
provide a general framework for the systematic analy-
sis of complex systems or processes.

The outline of this one-semester course is given
in Table 1, and a more detailed discussion of each

section of material is given below. Suggested refer-
encs in formulating the lecture for each section are
also given.
Mathematical Preliminaries
Some mathematical preliminaries may be neces-
sary, depending on the background of the students.
Generally, students should have been exposed to
some vector and tensor operations, such as summa-
rized in Appendix A of Bird, Stewart, and Light-
foot.E51 Additionally, some elementary concepts in
probability are desirable. Our undergraduate stu-
dents are exposed to such conceptse61 in the second-
semester engineering mathematics course. Regard-
less of the student backgrounds, however, I have
found it important to review both of the above before
proceeding with the core material.
A. Introduction: Molecular View of Gases, Liquids, and Solids
The purpose of this section of the course is to
present a qualitative molecular picture of gases, liq-

uids, and solids. Additionally, quantitative examples
are given to illustrate the usefulness of a molecular
interpretation of the three phases of matter.
An important dynamic feature of molecules is
their seemingly random motion. The mechanical
model shown in Figure 1 is a useful mechanical ana-
log of the random motion of molecules. In this model,
gravity causes the metallic balls to move down a
cascade of inclined planes. When projected onto a
screen, the balls appear to be under random molecu-
lar motion, as shown in Figure 2a. Of course, actual
random motion is due to the collisions between mole-
cules, where each molecule obeys Newton's Second
Law of Motion.
The same mechanical model can also be used to
provide a qualitative molecular picture of the three
phases of matter. In a gas, the average intermolecu-
lar spacing is much greater than the diameter of a
molecule or the average range over which intermol-
ecular forces act; this is depicted in Figure 2a. In
Figure 2b, a liquid is depicted by allowing all of the
metallic balls to settle to the bottom of the container
and then slightly tilting the container to one side.
Although the intermolecular spacing is relatively
small, there is a great degree of disorder in the mo-
lecular arrangements. This can be contrasted to a
solid, shown in Figure 2c, where the container is
tilted to an even greater angle. In solids, a regular
arrangement of the molecules is observed and vari-
ous types of packing geometries are possible.
In addition to the different geometric arrange-
ment of molecules in gases, liquids, and solids, the
trajectories or dynamics of the molecules are charac-
teristically different. In Figure 3, adapted from
Barker and Henderson,713 computer-generated tra-
jectories of molecules (see section G below) in the
three states of matter are shown. The tight spacing
and strong molecular interactions in solids cause
molecules to be constrained to move about fixed lat-
tice sites in a seemingly vibration-type motion. In

motions in a gas. (b) Intermolecular arrangements in liquids. (c) Intermolecular arrangements in solids.

liquids and gases, on the other hand, the spacing is
not as close and the interactions are not as strong,
and consequently the molecules have a less con-
strained motion.
The above discussions should lead to the recogni-
tion that the nature of the forces between molecules
is important in determining the molecular picture
and hence the properties of gases, liquids, and sol-
ids. A brief discussion of the Lennard-Jones poten-
tial is given in Bird, et al., although a more extensive
discussion ofintermolecular forces can be found.18'91
Although the above discussions are of a qualita-
tive nature, some very simple, yet motivating, quan-
titative examples can be given that illustrate how
the molecular picture can directly predict the ob-
served macroscopic properties of matter. The follow-
ing example, taken from Tabor,El0 illustrates the cal-
culation of the internal energy change for sublima-
tion of a crystal.

Example: The connection between molecular structure
and macroscopic properties: The internal energy change
for sublimation of an ionic solid.
The molecular structure of a NaCI ionic crystal is shown in
Figure 4. In the process of sublimation, a change from the crystal-
line state to the vapor state takes place. Neglecting any suba-
tomic contributions, the internal energy of the crystal is primarily
due to the electrical potential energy associated with the configu-
ration of the Na' and Cl ions. Considering any ion in the crystal,
we note that geometrically there are six nearest neighbors of op-
posite sign at the distance r from the ion, 12 neighbors of the
same sign at a distanceJ r, 8 neighbors of opposite sign at a
distance of/ r, etc.
According to Coulomb's Law, the total potential energy asso-
ciated with moving each ion to its position relative to the central
ion is
6e2 12e 8e2 2
+ ...= -A (1)
r + r ir r
where e is the electron charge and A is the so-called Madelung
constant determined from the infinite series summation in Eq. (1)
to three significant digits as 1.75.110
The above analysis is deficient in that other pair charge
interactions have been overlooked, i.e., in bringing any charge to
a specific location in the lattice, there will be Coulombic interac-
tions with all other charges in the lattice and not with just the
central charge in Figure 4. Consider, for example, an ion located
adjacent to the central ion in Figure 4. The potential energy of
interaction in bringing it from infinity to its place on the lattice
must include the pair interactions with all of its neighbors and
not just the central ion. Because of the regular geometric arrange-
ment of the lattice, however, the expression for the potential
energy interactions for locating this ion is exactly the same as
that calculated in Eq. (1) for the central ion. The total potential
energy in constructing the lattice is, therefore, obtained by sum-
ming Eq. (1) over all ions in the lattice.
We are still not quite correct, however, in that we have
counted all the pair interactions twice. If there are a total of N
ions in the crystal, the total potential energy in constructing the
lattice is finally given by

U= N[-A- (2)
Equation (2) represents a sum over pair interactions in the
crystal, or "pairwise additivity." A general representation and
discussion of pairwise additivity can also be given where Eq. (2)
represents a special case for the NaCl ionic crystal.
In order to finally compute the internal energy change for the
sublimation process, the internal energy of the NaCI vapor mole-
cules is needed. Each NaCl molecule is a neutral molecule and,
consequently, the total potential energy is obtained by multiply-
ing the electrical potential energy associated with the formation
of a single molecule by the total number of molecules, N/2. i.e.

Uvapor (3)
where r. is the interatomic distance for NaCl in the vapor state.
The internal energy change, per mole, for the sublimation
process represents the difference in electrical potential energy
between the vapor and solid states, which from Eqs. (2) and (3) is

Usub = 1Ne2( 1.75 1(4)
where No is the number of ions per mole. Using the values ofr =
(2.82)(10-8) cm and r, = (2.36)(10-8) cm given by Tabor101 the inter-
nal energy change for sublimation of NaCI crystal is calculated
from Eq. (4) as 65.3 kcal/mole. An experimental value can be

estimated from heats of formation data as 54.7 kcal/mole,[11 which
is in good agreement with the calculated value.
Many other examples of this nature can be used
to show the relationship between the molecular-level
description of matter and macroscopically observed
quantities. For example, Tabor also treats the prob-
lem of theoretically predicting the bulk modulus of a
crystal from knowledge of the molecular interac-
tions. These examples are very useful in motivating
the molecular treatments of transport phenomena
that follow in the remaining sections.
B. Transport Phenomena from Elementary Kinetic Theory
A simple, but elegant, treatment of the transport
properties of gases can be shown through the ele-
mentary kinetic theory of gases. The so-called phe-
nomenological laws of transport phenomena (Fick's
Law of Diffusion, Fourier's Law of Heat Conduction,
and Newton's Law of Viscosity) are also derived
through the elementary kinetic theory of gases. Con-
sequently, this is a very useful introductory theory
in establishing a firm physical foundation for dis-
cussing the phenomenological laws.
In general, mass, momentum, and energy can be
transferred by a substance through random motions
and interactions of its constituent molecules. This
transfer takes place even in the absence of any over-
all or bulk-material motion. An everyday example is
the rapid sensation of odors in a closed room, with-
out drafts, at locations many meters away from the
source of their emission. Here, random molecular
motion is the driving force for a macroscopic transfer
of material.'
The phenomenon of macroscopic transfer as the
result of random molecular motion is illustrated in
Figure 5, which shows molecules of two different

transfer of material. Closed circles and open circles are

types, depicted as open and closed circles. The left-
hand side of the plane at z = 0 is more concentrated
in open circles than in closed, although the total
number of circles is equivalent on both sides of the
plane. One of the basic hypotheses of the elementary
kinetic theory of gases is that a gas is comprised of
molecules in constant random motion. Although this
randomness is in all directions, for the sake of sim-
plicity we will consider only one dimension. For ex-
ample, consider random molecular motion in the z-
direction, as shown by the arrows randomly affixed
to each molecule in Figure 5. This could be accom-
plished by a series of coin tosses where a "heads"
corresponds to an arrow pointing to the right, and a
"tails" results in an arrow pointing to the left.
Over a small interval of time, several molecules
will be transferred from the left-half to the right-half
plane, and vice-versa, owing to random molecular
motion, with the total number of molecules on either
side of the plane remaining essentially unchanged
(no overall motion). Because of the imbalance in
concentrations, the several molecules transferred
from the left-half to the right-half plane are pre-
dominantly open circles, whereas the several mole-
cules transferred from the right-half to the left-half
plane are predominantly closed circles. Thus, there
will be a net transfer of open circles from a more
concentrated region of open circles to a lower con-
centrated region of open circles. Likewise, the closed
circles also are transferred from a region of high
concentration of closed circles to a region of lower
concentration of closed circles. Random molecular
motion statistically tends to equalize concentration
differences that exist in a system. The macroscopic
observation is a net transfer of a molecular property
in a direction from a high property concentration to a
low concentration.
In addition to molecules being characterized as a
certain type or species, molecules also possess the
properties of momentum and energy. Since momen-
tum is a vector quantity, there are three scalar com-
ponents of momentum that are considered as sepa-
rate properties. Gradients in the concentration of
these properties (x, y, or z momentum/volume and
energy/volume) will also result in a transfer of those
properties through the system by random molecular
There are many excellent quantitative develop-
ments of the elementary kinetic theory of gases that
follow from the above qualitative description. A very
concise quantitative treatment of the elementary

cally large group of molecules.

kinetic theory of gases is given by Hirschfelder, et al.
Other elementary transport theories for liquids and
solids can also be discussed, e.g., the Eyring theory
of transport phenomena in liquids.
C. Phase Space and Liouville's Equation
The purpose of this section is to develop the so-
called Liouville equation, which is the starting point
in the derivation of the transport equations and
associated flux relations (see Section E below).
There are several introductory and clearly writ-
ten developments of the Liouville equation that can
be consulted for this section of the course,[12-14] and
only some highlights will be given here.
In this section and the remaining sections, we
consider only molecules of a single type or species;
the transport phenomena of multicomponent sys-
tems is beyond the scope of an introductory, one-
semester course.
The first part of this section of material discusses
the concepts of phase points and phase space. The
phase point represents the collection of all momen-
tum and position variables of the molecules in the
system at any time. As the molecules move accord-
ing to Newton's Second Law of Motion, the phase
point moves through a multidimensional space con-
sisting of the momentum and position coordinates of
all the molecules in the system. I have used simple
cartesian coordinates in an undergraduate class.
However, some instructors may wish to introduce
the concept of generalized coordinates and Hamil-
tonian equations of motion.
Next, the concept of an ensemble of phase points
is introduced. Each phase point or member of the
ensemble initially consists of the same total number
of molecules, same total momentum, and same total
energy. There are, however, a number of different
ways or realizations in distributing the initial posi-
tions and moment of the molecules in order to
achieve the same total values in energy and momen-
tum macroscopicallyy indistinguishable systems). The
collection of these realizations can be visualized as a
"cloud" of phase points at any time. A number den-
sity function is introduced to quantify the "cloud"
that moves through multidimensional space.
An analogy can immediately be drawn between
the number density function for the phase points
and the ordinary mass density function introduced
in the first undergraduate transport course in fluid
mechanics. In fact, the Liouville equation simply
represents a conservation equation for the phase
points as they move through multidimensional space.
I have used Figure 2.1 in Bird, et al., as a start-

ing point in visualizing the development of the
Liouville equation. An analogous figure can be
thought of where a simple cube is replaced by a
"hypercube" and the cartesian coordinates replaced
by multidimensional coordinates (see Figure 6.4 of
Reif131). The rate of phase points entering the hyper-
cube through any of the faces is simply the flux
times the cross-sectional area (multidimensional in
this case). The flux is simply the number density
times the time rate of change of the coordinate nor-
mal to the face of the hypercube. Specific units are
presented for both momentum and position coordi-
nates to dimensionally verify that a "rate of phase
points" is obtained for each term.
The final development involves substitution of
Newton's Second Law of Motion for each molecule
and some simple reductions, although again gener-
alized coordinates and Hamiltonian equations can
be used for a more rigorous treatment. More discus-
sion on the types of ensembles (microcanonical, ca-
nonical, etc.) could also be given at this time, but it is
not necessary for the developments given below.
D. Reduced Distributions and Equilibrium Behavior of Matter
The Liouville equation derived in the previous
section describes the behavior of the phase point
number density function in a multidimensional space
consisting of all momentum and position variables
for the molecules in the system. Since the number of
molecules in a system is typically very large (over a
billion!), the solution of the Liouville equation repre-
sents a formidable problem. Fortunately, it will be
shown in later sections that generally it is only nec-
essary to know the behavior in a reduced space rep-
resenting the positions and momentum of only a few
molecules. Physically, this is because the interac-
tions between molecules which lead to correlated
behavior are generally of a short range and, thus,
locally involve only a few molecules.
The phase point number density function, nor-
malized with respect to the total number of mem-
bers of the ensemble can also be interpreted as the
probability of finding a member of the ensemble in a
differential region of phase space. Below, this func-
tion is denoted as p(rN, pN, t) where (r", pN, t) is
shorthand notation for the multidimensional posi-
tion and momentum coordinates (rl, r2, ..., rN, p1, p2
..., pN, t). With this probability interpretation, the
various types of reduced density functions and rela-
tionships between systems of distinguishable and
indistinguishable molecules can be presented." 813
With the above preliminaries, the reduced form
of the Liouville equation can be derivedsl8. The deri-
vation requires the use of Green's theorem and the
Chemical Engineering Education

assumed "natural" behavior of the phase point num-
ber density function that it tends to zero as the
position and momentum variables of the molecules
tend to infinite values.
The configurational part of the reduced Liouville
equation is useful in the development of equations of
state and thermodynamic properties of gases, liq-
uids, and solids. This equation can be derived as
outlined by Hirschfelder, et al., and is recognized by
statistical thermodynamicists as the "Integral Equa-
tion" for lower-ordered configurational distribution
functions (see Section F below).
E. The General Equations of Change
It is the purpose of this section of the course to
develop the transport equations (or mass, momen-
tum, and energy conservation equations) from first
principles. Although many introductory texts on
kinetic theory and transport phenomena derive the
transport equations beginning with the so-called
Boltzmann transport equation (Section F below), fol-
lowing Irving and KirkwoodE151 we prefer to adopt a
general approach and derive the transport equa-
tions directly from the Liouville equation developed
in Section C. The resulting "General Equations of
Change" are applicable to all types of flows, includ-
ing laminar, turbulent, and shock flows, thus form-
ing an important basis for understanding current
and future developments in transport phenomena.
As mentioned in the previous section, the nor-
malized phase point number density function PN can
be interpreted as a probability density function, i.e.,
pdrNdpN is proportional to the probability of finding
a phase point in a multidimensional region between
(rN, pN) and (rN + drN, pN + dpN) at any time. Just as
one defines the mean, variance, and other moments
of probability density functions, we can also exam-
ine these quantities with respect to the phase point
(probability) density function. More specifically, the
averaging can be performed directly with the
Liouville equation leading to the so-called transport
equations. The transport equations thus represent
the behavior of the various moments of the density
function PN. These moments are defined more spe-
cifically below. Since the Liouville equation is a con-
servation equation, the transport equations also
represent conservation equations for the various
moments of the density function.
Following Irving and Kirkwood, the average or
expectation value of any dynamical variable
a(rN, pN) that does not depend explicitly on time is
introduced as
E{a}= N!j a(rN,pN)fN(rN,pN,t)drNdpN (5)

where fN(rN, pN, t) = N!pN(rN, pN, t) is the phase point
density function for indistinguishable molecules.
A judicious choice of a leads to the definitions of
the average mass (or number) density, average mo-
mentum, and average energy for the fluid as fol-
1) Average Total Mass Density, E(al = p(r, t)
Ka=m Y8 (-r) (6)
where m is the mass of a single molecule and 8 is the
Dirac delta function.
2) Average Total Momentum Density, Elal = p(r, t)v(r, t)
a=m k(r -r) (7)
3) Average Total Energy Density, E(a) = U(r, t)
a N 1N N
a= -1 P28(rk-r)+2i1 Y Y ij8(rj-r) (8)
k=1 2i=1 j=l
Note that the first term in Eq. (8) represents the
kinetic energy contribution, and the second term
represents the intermolecular potential energy con-
The transport equations can now be derived us-
ing the simple paradigm of multiplying the Liouville
equation by each of the defining relations for a and
integrating over all phase space. Since there are
some similarities in each derivation, this process
can be facilitated by first considering the conserva-
tion equation for a.lS,615 Generally, finding time to
derive the energy balance equation has been diffi-
cult. For the purposes of this introductory course it
is sufficient to derive the mass and momentum con-
servation equations and merely present the results
for the energy conservation equation.
Finally, it should be noted that in the derivation
of the transport equations, use is made of the inte-
gral relationship involving the derivative of the Di-
rac delta function16,171

Jg(x)8(n)(x-x)dx= (-1)n g(n)(xo) (9)

where 6(n) denotes the nth derivative of 5 with respect
to x and, similarly, g("(xo) is the nth derivative of g
with respect to x evaluated at xo. The derivation of
Eq. (15) can be easily obtained by using one of the
limiting definitions of the delta function (a general-
ized function) e.g., the limit of a normal or Gaussian
density function as the variance tends to zero.
F. Transport Properties and Solutions to the
Reduced Liouville Equation
The general equations of change derived in the
previous section contained expressions for the prop-
erty flux vectors representing the transfer of a prop-
erty relative to the mass average velocity of the

Fall 1991

fluid. It was shown that these expressions contain
lower-order density functions whose behavior is dic-
tated by the corresponding reduced forms of the
Liouville equation introduced in Section C.
It is the goal of this section to show that various
types of solutions to the reduced Liouville equation
result in a form of the transport equations known as
the Navier-Stokes equations. This derivation can be
rigorously accomplished for dilute gases which, by
definition, have at most only two molecule encoun-
ters; three or more molecule interactions are ne-
glected. Consequently, the reduced Liouville equa-
tion derived in Section E can be truncated at order
two for a dilute gas. From this truncated equation a
very simple derivation of the so-called Boltzmann
transport equation can be given.1181 Note that some
discussion on the geometry and dynamics of a binary
molecular collision is necessary in the development
of the Boltzmann equation.
Having derived the Boltzmann transport equa-
tion, scaling and dimensional analyses are per-
formed.'119 The Knudsen number, the ratio of a char-
acteristic molecular length scale (such as the gas
mean free path) to a characteristic macroscopic length
scale, is introduced as an important dimensionless
group for the Boltzmann transport equation.
By considering the two extremes (i.e., very small
and very large Knudsen numbers), various approxi-
mate analytical solutions to the Boltzmann equation
can be outlined. Unfortunately, there is not suffi-
cient time in a one-semester course to cover these
solutions in great detail. Typically, I have outlined
the Chapman-Enskog solution to the Boltzmann
equation, asymptotically valid at very small Knudsen
numbers. This discussion includes the Boltzmann
H-Theorem, the first-order perturbation expansion,
and the general forms of the solutions. The overall
presentation is sufficient to obtain the celebrated
Navier-Stokes equation and the energy transport
equation encountered in the students' previous
courses on transport phenomena. Newton's Law of
Viscosity and Fourier's Law of Heat Conduction are
shown to naturally arise in the Chapman-Enskog
solution method. The expressions for the coefficients
of viscosity and heat conduction are also obtained.
However, it is shown that further resolution of these
expressions is needed (via solutions to a set of finite
integral equations) in order to perform actual nu-
merical calculations. Typically, there is not suffi-
cient time to cover the solution to these specific
integral equations, nor is it necessary at this level,
and the final results can be presented without proof.

The above discussions and presentations are also
sufficient for demonstrating the connection between
thermodynamics and transport phenomena. It is
readily shown that, under local equilibrium condi-
tions, the normal component of the pressure tensor
in a dilute gas is the thermodynamic pressure. For
fluids that are far removed from local equilibrium, it
is doubtful that the thermodynamic pressure can be
utilized in a transport equation. Nonetheless, a gen-
eral framework has been established for evaluating
the pressure tensor in both equilibrium and non-
equilibrium fluids; similar analyses can be applied
to the evaluation of the internal energy.
A homework assignment can also be given that
ties together thermodynamic and transport proper-
ties for dilute gases: experimental values of the sec-
ond virial coefficients for a variety of dilute gases are
used to determine the corresponding Lennard-Jones
force constants.8 1 The Lennard-Jones constants de-
termined in this manner are, subsequently, used to
predict the viscosity coefficients of each gas accord-
ing to the Chapman-Enskog formula.
Some instructors may wish to present other solu-
tions to the Boltzmann transport equation, such as
Grad's 13-moment method; some recent reviews on
solutions to the Boltzmann transport equation are
given by Cercignani[191 and by Dorfman and van
Beijeren.1201 A condensed discussion of the Chapman-
Enskog method is given by McQuarrie[211 and a read-
able discussion is given by Vincenti and Kruger.1221
G. An Introduction to Molecular Dynamic Computations
Given the dramatic advances in the scientific
and engineering computational abilities provided by
supercomputers and other machines, it is highly
likely that many problems in transport phenomena
will, in the future, be solved at the molecular level.
It should be clear from the above discussions that
the numerous approximations involved in actually
resolving the transport equations limits the useful-
ness of the results for performing engineering calcu-
lations for a variety of different systems, other than
systems of dilute gases. Although extending the use-
fulness of the statistical mechanical development of
transport phenomena is a subject of current engi-
neering and scientific research, molecular dynamics
computations provide a fundamentally simple and
rigorous means of studying transport phenomena
for almost all classical fluids.
There are many books and review articles on the
molecular dynamics method. No attempt is made
* For a review of nonclassical or quantum mechanical methods for
molecular dynamics, see Kosloff.'25'

Chemical Engineering Education

here to review the literature in this area. Rather,
some suggested discussions and topics are given that
are useful as further expositions of the topics cov-
ered in the previous sections. It is important that
the students understand the basis and salient fea-
tures of the molecular dynamics method and see the
usefulness of the method in predicting equilibrium
or nonequilibrium properties of matter.
A recent text by Heermann1231 discusses a num-
ber of important aspects of the molecular dynamics
method, including finite difference schemes for solv-
ing the equations of motion for the molecules, peri-
odic boundary conditions and minimum image con-
vention, types of ensembles, and averaging methods
for determining macroscopic properties. Heermann
also lists a number of computer programs associated
with the molecular dynamics method. For example,
a clearly presented computer program listing is given
for microcanonical (constant energy) emsemble equi-
librium molecular dynamics. This program can be
readily installed on a mainframe computer or net-
work system. As an enlightening homework assign-
ment,1231 the students can be asked to determine the
equilibrium pair correlation function for a Lennard-
Jones fluid discussed in Section D above. Compari-
sons between dilute gases, dense gases, and liquids
can be made, as well as the study of other types of
intermolecular potentials and equations of state.
Instructors may also wish to present other types
of molecular dynamics methods or applications, in-
cluding nonequilibrium molecular dynamics meth-
ods.[241 Because of the conceptually simple basis of
molecular dynamics, instructors can have a great
degree of flexibility (and fun!) in bringing their own
interests into developing this part of the course.

In general, I have found this course suitable as
an upper-level chemical engineering elective course.
A final student project is substituted in place of a
final exam. The students can select any project that
illustrates a molecular interpretation of the macro-
scopic properties of matter. Ideally, these topics
should be taken from areas not fully treated in the
lecture material, such as molecular design in solids,
multicomponent systems, and other molecular dy-
namic or Monte Carlo simulation methods. Specific
applications or potential applications to systems of
interest to chemical engineering and related disci-
plines should be emphasized in the students' proj-
ects. These additional topics could also be developed
in a second-semester course where greater emphasis
could be placed on molecular level engineering de-

Fall 1991

sign of materials and processes.
Although the lecture material is taken from a
number of different sources (a course text is cur-
rently in preparation), any introductory book on sta-
tistical mechanics or statistical physics, some of which
are given in the references, should be used as a
required supplementary text for the course. These
texts can provide a source of homework problems
and can be used as a basis for the development of
some of the material suggested above.

Award Lecture


From There, To Here, To Where?

Part 1: Computing

The ASEE Chemical Engineering
Division Lecturer for 1990 is Brice Car-
nahan of The University of Michigan.
The 3M Company provides financial
support for this annual lectureship
award, and its purpose is to recognize
outstanding achievement in an impor-
tant field of ChE theory or practice.
Brice earned his BS and MS de- \
grees from the Case Institute of Tech-
nology (1955, 1956), and his PhD from
the University of Michigan in 1965, all in chemical engineer-
ing. His doctoral research was on radiation-induced cracking
of paraffins. Between 1959 and 1965, he worked closely with
Professor Donald L. Katz, first as technical director of the
Ford Foundation project Computers in Engineering Educa-
tion and then as associate director of a follow-on NSF project,
Computers in Engineering Design Education.. He joined the
faculty of the University of Michigan in 1965, where his
research activities have focused on applied mathematics, mod-
eling, digital computing, and development of software for
computer-aided process analysis and dynamic simulation. He
is coauthor of two Wiley Texts, Applied Numerical Methods
and Digital Computing and Numerical Methods.
He and his colleague, Professor James Wilkes, are re-
sponsible for the required computing course for all freshmen
engineering students at the University of Michigan, for which
they have produced a steady stream of texts and instructional
aids over the years.
Professor Carnahan was a founding member and first in-
terim chairman of CACHE. He has subsequently served as
CACHE vice-chairman and chairman, and is currently active
as board member and publications chairman. He has held
elected AIChE positions as CAST Division Director, Vice-
Chairman, and Chairman, and is a member of the Editorial
Board of Computers & Chemical Engineering.
Since the early 1980s, Professor Carnahan has been inti-
mately involved with the planning, implementation, and
management of the Michigan College of Engineering
heirarchical, multivendor network, now incorporating over
2000 attached machines of widely varying power.
He has received numerous honors, including the Univer-
sity of Michigan's Distinguished Service Award (1974), the
AIChE CAST Division Computers in Chemical Engineering
Award (1980), the University of Michigan College of Engi-
neering's Outstanding Teaching Award (1984), and the De-
troit Engineering Society's Chemical Engineer of the Year
Award (1989).

Notice of the 3M Lectureship award for 1990
came to me as a complete, though a very pleas-
ant, surprise. Many chemical engineering academics
have had greater impact on their specialties, includ-
ing engineering computation. Nevertheless, I very
much appreciate this singular recognition.
I would be remiss if I did not here acknowledge
the special contributions of two Michigan faculty to
my professional life and, indirectly, to this award.
The first is Don Katz, one of the greats of 20th
Century chemical engineering, who provided me at a
young age with opportunity, responsibility, encour-
agement, and financial support for pursuing my in-
terests in chemical engineering computing. He is
sorely missed by all who knew him. The second is my
colleague, Jim Wilkes, with whom I have worked
and taught on an almost daily basis for the past
thirty years. That sounds like a long time, but in
fact, the years of our collaboration have passed all
too quickly. They have been filled with much work, a
sense of accomplishment, and lots of fun. Thanks,
Jim. It's been great working with you. Here's to the
future...and, yes Jim, I will work on that revision of
Chapter 6...soon....

It is a bit disconcerting to be introduced as an
"expert" on almost any topic, since the audience then
expects the speaker to make the complicated simple,
to provide clever insights into the nature of a phe-
nomenon, or to predict the future accurately. It is es-
pecially onerous to be labeled a "computing" expert.
The truth is that no individual can get a handle on
more than a few small subspaces of what has be-
come an enormous and amorphous computing uni-
verse, including, but not limited to:
1. Design and manufacture of hardware for symbolic
(mostly numerical) operations, storage, display, and

communication (e.g. networks)
2. Ancillary electronic equipment (e.g., sensors, a/d
3. Software (e.g., operating systems) for hardware
management, communication, and user interaction
4. A wide variety of procedural, object-oriented, and other
tools for creating applications
5. Application programs for:
Creating and publishing documents
Organized storage and retrieval of information
Business and financial transaction/record keeping
Implementation of numerical and non-numerical
Engineering/scientific analysis, design, control, and
Creation of graphical images
Visualization of computed results
Image analysis and pattern recognition
Integrating media (text, graphics, video, sound, TV) for
education and entertainment
Knowledge-based tools predicated on rules and
Language, semantics, organization of the brain and
human thought processes
Everyone, both lay and technically trained, is
profoundly affected by "computing," but each of us
has a private version of what computing is, based on
our own limited experience (much like the elephant
and the blind men).
I chose the lecture title primarily because this is
a meeting of engineering educators, and few techno-
logical developments have had (and will in the fu-
ture have) so pervasive an impact on engineering
education and research as has digital computing.
Unlike many important technological developments
in the history of engineering, computing has not
"matured" after fifty years of steady (often spectacu-
lar) advances. In fact, as we enter the last decade of
this century, the pace of change is accelerating sig-
nificantly in all of the areas listed above. The ques-
tion mark in the title will let me end with some
conjectures about current trends and the future.
Computing developments in engineering educa-
tion have occurred by and large during my profes-
sional lifetime, starting in the mid-1950s. I would
like to start from the perspective of a newly gradu-
ated (in 1955) chemical engineer, trace some of what
I perceive as the most important computing develop-
ments over the past fifty years or so, and then make
some predictions (guesses, really) about what the
future may hold vis-a-vis computers and computing
in engineering education. I chose to put "engineer-
ing" rather than "chemical engineering" in the title
because computing in chemical engineering isn't all
that different from computing in other engineering

I would like to ... trace some of what Iperceive
as the most important computing developments
over the past fifty years or so, and then
make some predictions (guesses,
really) about the future ...

In fact, many of the computing tools used most
by both students and faculty (e.g., word processors,
data-base managers, spreadsheet programs, draw-
ing and plotting packages, electronic mail and con-
ferencing software) are essentially "non-technical";
of course, "technical" computing (involving large-scale
programs for symbolic and numerical mathematics,
analysis, design, and control) is also important to all
of us some of the time, and I don't want to leave it
out-I just want to take a broader view of what com-
puting in engineering education is now and what it
is likely to be in the future.

Let's start with the "there" part of my title. "There"
for me started when I graduated from Case Tech in
1955, within months of the introduction of the IBM
650, the first widely available commercial digital
computer. That event passed without my knowl-
edge. I had heard of (and seen, on television) the
UNIVAC computer, mostly because of its use in tabu-
lating and predicting the vote in the 1952 presiden-
tial election. The only computing device I had seen
personally was an enormous unused mechanical
analog integrator (covering perhaps two-hundred
square feet of floor space) in the ME department at
Case that had been used to solve some ODE's during
World War II. The twelve-foot long K&E sliderule
hanging on the wall of the same room looked a lot
more useful to me. It was a prop for teaching new
freshmen about fast and accurate calculation (three
digits still isn't all that bad!). That giant rule, along
with the dreaded drafting exercises (where were you,
Claris CAD, when I needed you?), is retained vividly
as part of my freshman memory.
I am surprised at how little most students (and
faculty) know about the personalities and historical
events that led up to the successful IBM 650 ven-
ture. Mention "light-bulb" and the response is
"Edison"; "airplane" and the response is "Orville and
Wilbur Wright"; "telephone" and the response is
"Alexander Graham Bell"; "computer" and the re-
sponse is (almost always) silence or (inaccurately)
"IBM." Although many mechanical or electromechani-
cal calculating machines were developed (very early
by Pascal, late in the 19th Century by Burroughs
and Hollerith, and during the first half of the 20th

War II. Some statistics: the machine was 100 feet
long, 8.5 feet high, and several feet wide; it had
twenty 10-digit registers in its arithmetic unit (each
2 feet long), and 18,000 vacuum tubes. An integer

machine the EDVAC. EDSAC, built by Wilkes at
Cambridge University, was the first true stored-
program machine built on the EDVAC model; it be-
came operational in 1949.
The first American stored-program machine was
the BINAC, built for Northrup Aviation by Eckert
and Mauchly (who left the Moore School in 1947 to
start their own company). It was fully functional by
mid-1950 and served as the basis for the first com-
mercial digital computer, the Remington-Rand
UNIVAC, released in 1951; forty-eight UNIVAC sys-
tems were built, and the cost per machine was
$250,000 (about $3 million in today's dollars).
IBM entered the digital computing business
shortly after Remington-Rand, introducing its first
computer, the IBM 701, in 1952; nineteen were built.
The IBM 701 was the first stored-program machine
to use truly random access magnetic core memory
(previously developed at MIT in 1947 for a special-
purpose radar signal processor called the Whirlwind).
At the same time, IBM was developing two other
machines. One was a follow-on core-memory ma-
chine with the first built-in floating-point unit, the
IBM 704; it was not really available in quantity
until 1957-58. The second was a less expensive "mass-
market" computer, the IBM 650, with a magnetic
drum memory. IBM eventually built several hundred
of them, mostly for rental. The University of Michi-
gan rented an IBM 650 in early 1956 to replace its
mostly unsuccessful research computer with mer-
cury delay line storage called the MIDAC (MIchigan
Automatic Digital Computer). The few who actually
Fall 1991

used MIDAC derisively said the acronym really stood
for "Machine Is Down Almost Continuously." As I
recall, the rental rate for the 650 was $35 per day-
time hour (but only for hours when it was up!).
The presence of the new computer had nothing to
do with my decision to go to Michigan for PhD work
in the fall of 1956. I chose Michigan because it was
one of the few schools with its own nuclear reactor,
and I wanted to work with Joe Martin on a chemical/
nuclear engineering problem. When I met with Joe
for my first counseling session, he told me about the
new University computer and that the mathematics
department was offering a new course on digital
computing, the first at Michigan. Once I was in that
course (with about twenty other students) I knew
that I wanted to be involved with computers far into
the future (even though my research was to be unre-
lated to it). In fact, I became a teaching assistant in
that first computing course the next term it was
For those (most of you) who weren't around at
that time, here is a picture of what students did
during that first course offering:
Each of us learned to operate the computer and then
signed up for, at most, one hour at a time to solve our
problems (I always ended up with the 2:00-3:00 AM slot!).
The machine had no keyboard or printer-just a card
reader and card punch. All communication was through
punched cards or directly with keys on the console (the
lights displayed information in bi-quinary format-you
might want to look that one up!).
All programming was in the machine's language; each
instruction contained an operation code plus two
addresses, one for an operand and another for locating
the next instruction in the memory.
The "operating system" consisted of a four-card machine-
language loader. Program execution could be initiated,
interrupted, or stepped one instruction at a time, directly
from the console; the light pattern on the console was the
only feedback available to the programmer/operator (the
repeated light patterns from infinite loops were always
fun to watch).
The machine had a rotating-drum memory with fifty
memory cells arranged in each of twenty "cylinders'
around the drum surface. Because of the time required for
interpreting an instruction, retrieving the operand, and
then processing the instruction, placement of both the
data and the next instruction was critical for efficient
execution. The location of each program instruction and
data item on the drum had to be carefully considered,
since a drum is not a random-access device.
How do you think a current student working on a
Macintosh would respond to the following directions?
If the instruction address is an even number, the data address
should be three word positions later (on any cylinder) and
the next instruction address should be four word positions
beyond that. Since there are fifty word positions around the
cylinder, the correct drum rotation angle for the next

instruction if 50.4 degrees. ... If the instruction address is
odd, the data address should be three word positions later
and the next instruction address should be five positions
beyond that, so the drum rotation angle for the next instruction
is 57.6 degrees.
Not to worry-part-way through the course we
began to use the GAT assembler, written by Gra-
ham, Arden, and Galler of the University of Michi-
gan Computing Center. That helped a bit (symbolic
names for operation codes and addresses) but still
left the angle determination to the programmer. Then
one day, late in the term, the SOAP assembler ar-
rived. .and life was never the same thereafter. The
O in SOAP stood for "optimal," and the SOAP as-
sembler took care of all those nasty angle details.
After struggling with the machine's language, SOAP
seemed nothing short of a miracle (I was amazed,
like the monk in the XEROX ad).
I still have my programs from that course. The
first was (you guessed it), "Find the volume of a
cylinder, given the radius and height as data." I re-
member thinking that I could have done the whole
thing on a slide rule in a tiny fraction of the time it
took me to learn how to run the 650 and get the
program working. But later in the course we were
each asked to solve a problem of our own. I decided
to solve the two-dimensional heat-conduction
(Laplace) equation in an L-shaped section of a fur-
nace wall. I can still remember the thrill of getting
the program working-and not just working, but
working with variable mesh sizes. It was my first ex-
posure to the true power of the computer and of
numerical methods.
For me, the computer die was cast!

In those very early days, it was clear to me that
computers would get faster, more reliable, and less
expensive-but not that they would get incredibly
smaller, and orders-of-magnitude faster and cheaper
(on a $/instruction or $/memory location basis). Data
from the recent (already classic) text on computer
architecture by Hennessy and Patterson'41 on the
relative performance of several classes of computers
over the past twenty-five years or so is shown in
Figure 3. The performance index is based on the
time to completion of a mix of typical programs.
By and large, prices in current dollars of the
various categories of machines have stayed fairly
stable. Supercomputers typically cost many millions,
mainframes sell for $500,000 to several million,
minicomputers from $50,000 to $500,000, and mi-

crocomputers from $1,000 (minimal personal com-
puters) to $75,000 (for high-performance worksta-
tions). Note that the rate of improvement in the per-
formance index is undiminished over a twenty-five-
year span and varies from about 18% per year for
supercomputers to about twice that for microcompu-
Figure 4 shows a different performance index for
supercomputers and microprocessors that is particu-
larly relevant to numerical engineering computa-
tions, MFLOPS (Millions of Floating-Point Opera-
tions Per Second). Although supercomputer proces-
sors still perform floating-point operations one to
two orders-of-magnitude faster than the fastest cur-
rent microprocessors, the message here is clear: the
latest RISC (Reduced Instruction Set Computer) mi-
croprocesors (the middle curve) portend a rapid clo-
sure of the floating-point performance gap by rela-
tively inexpensive microprocessors.

creases over the past decade for DRAM (Dynamic

dollars. Note that for each chip category there is a
similar pattern of a steep (nearly ten-fold) fall in
prices as the chip goes into production and that the
price cycles are almost identical despite the succes-
sive quadrupling of capacity.
Some long-range trends in computing equipment
development are:E41
Performance growth ranges from 18% per year for
supercomputer processors to 35% per year for
Dynamic RAM chip element density increases about
60% per year. 4-Mbit chips are now in mass production
and IBM has announced plans to begin producing 16-
Mbit chips. Hitachi has already fabricated a 64-Mbit
chip in its laboratories.
Chip transistor count increases about 25% per year,
doubling every three years.
Hard disk bit density increases about 25% per year,
doubling every three years.
Hard disk access time improves slowly (only 3 to 4%
per year).

Who, in the late 1950s, would have guessed that
national computer meetings that brought together a
few hundred participants then would, only thirty
years later, sometimes attract in excess of 100,000
attendees-and be held only in one or two dreadful
places like Las Vegas and Anaheim for lack of room
elsewhere? Who then could have guessed the scope
of the computing business now?
Well, some did. I remember a talk by Thomas
Watson, Jr., in 1959, at the dedication ceremony for
the University's new IBM 704. He predicted that by
1990, the computing business would be as big as the
automobile business. That didn't quite happen, as
sales by the major computer companies are still sub-
stantially smaller than for the major auto manufac-
turers. Of course, had the car companies delivered
performance improvements comparable to those for
the products of the computing industry, we would all
be driving $1 Ferraris across the continent in a few
seconds, and car-company sales might not look so
big (one disadvantage-the car would be very, very
small!). If revenues from information-related busi-
nesses such as communication are added to those for
the computing manufacturers, Watson's prediction
has probably already come true. In any event, it is
certain to come true before the turn of the century.
Oh, that I had had some investment cash in 1959!

What about other early predictions? In 1945,
Vannevar Bush, inventor of the electronic analog

computer at MIT and Director of the Office of Scien-
tific Research and Development during World War
II, postulated a future device that is clearly similar
to the personal computer we (almost) all know and
love. In an article entitled "As We May Think,"E61 he
The MEMEX will be for individual use, about the size of a
desk, with display and keyboard that would allow quick
reference to private records, journal articles, newspapers,
and perform calculations.

Unfortunately, in 1967, in an article entitled
"MEMEX Revisited," he wrote:
Will we soon have a personal machine for our own use?
Unfortunately not!

How wrong he was, with the first microprocessor
only a few years away. Of course, Vannevar Bush
had apparently been wrong before. As a consultant,
he is reputed to have advised IBM in the early 1950s
that one-hundred IBM 650s would saturate the
market, since they could do all the computing that
the world needed done! (Could he have been right?)
After hearing many predictions over the years, I
don't think that even the brightest are good at pre-
dicting the future of computing much beyond the
next generation of hardware and software. This is
not to be critical. Who among us in 1956 (slide rule
hanging from belt) would have predicted that in
1990 I could buy a pocket calculator for $50 (in
greatly inflated currency) that uses a procedure-
oriented language, can retain several programs in-
definitely, computes to at least eight-digit accuracy,
and operates for months on end on a battery smaller
than a dime?

Table 2 shows a chronology of major hardware/
software developments during the past three dec-
ades, as I see them. I have verified most of the dates,
but a few are from my own recollection and may be
off by a year or two.
Having gone from "there" to "here" in the general
categories of hardware and software, Table 3 shows
several areas of chemical engineering where these
technologies have had the biggest impact. Here I
have not tried to arrange the list in strict chronologi-
cal order.

book review

Second Edition

Chapman and Hall, New York (1990) $115

Reviewed by
Mark E. Orazem
University of Florida

In their preface, the authors write that "... elec-
trochemistry and electrochemical engineering as aca-
demic disciplines ... remain insufficiently taught at
both undergraduate and post graduate levels." Their
perspective is shared by others. The National Asso-
ciation of Corrosion Engineers (NACE) is currently
forming a task group to find ways to improve corro-
sion education in this country. In spite of the fact
that electrochemical systems encompass one-ninth
of the chemical process industry, most chemical en-
gineering undergraduates receive no exposure to the
field beyond a two-week stint in a physical chemis-
try class. The authors express their hope that "this
book will encourage many more teachers to take up
the challenge of teaching an integrated applied elec-
trochemistry course."
This text provides a compelling demonstration of
the importance of electrochemical processes. In ten
chapters and 460 pages the authors explore:
1. Electrolytic production of chlorine and caustic
2. Electrolytic extraction, refining, and produc-tion of
metals through electrowinning, cementation,
electrorefining, and electro-deposition of metal
3. Electrolytic production of a number of low-tonnage
inorganic products such as fluorine, hydrogen
peroxide, ozone, and manganese dioxide
4. Organic electrosynthesis of adiponitrile (used to make
nylon) and other commercial electro-synthesis
5. Waste-water treatment by electrochemical processes
such as electrodeposition of metal ions, in-situ
formation of oxidizers, and electrodialysis
6. Metal finishing including electroplating, electroless
plating, and electrophoretic painting
7. Metals processing, including electroforming and
electrochemical machining and etching
8. Corrosion and corrosion control
9. Batteries and fuel cells

10. Electrochemical sensors and monitoring techniques
This text provides a broad overview of electro-
chemical technology, and the detail with which these
systems are covered is sufficient for a survey course.
The review of electrochemical practice is preceded
by two chapters that cover the fundamentals of elec-
trochemistry and electrochemical engineering. The
discussion of fundamental electrochemical concepts
(Chapter 1) is very compressed and may be tough
going for the typical undergraduate chemical engi-
neer. It does, however, outline the key factors that
distinguish electrochemical processes from traditional
chemical systems. The section on electrochemical
engineering (Chapter 2) emphasizes costing of electro-
chemical processes and introduces typical cell de-
This text could be used for an elective survey
course directed to senior undergraduate students
and beginning graduate students. The strength of
the book, in this application, is its comprehensive
overview of the field. The authors, however, do not
make it easy for the instructor. The text does not
include homework problems and, while general sug-
gestions are made for further reading, specific attri-
butions are not given for the material presented in
the chapters. Therefore it is difficult to know pre-
cisely where to look for more information on a spe-
cific topic.
The discussion of fundamentals is not integrated
into the discussion of industrial processes. While the
authors stress the importance of current distribu-
tion in Chapters 1 and 2, such calculations are not
employed for the design of industrial processes cov-
ered in Chapters 3 through 12. For example, the
authors present different battery types in Chapter
11, but do not present the manner in which one
would try to optimize the battery design based on
principles governing current and potential distribu-
tion. Impressed current cathodic protection is pre-
sented in Chapter 10 as a means of controlling corro-
sion, but the equations used to design a cathodic
protection system are not presented. This level of
coverage is suitable for a survey course. For an ad-
vanced graduate-level class, I would want to apply
the fundamental concepts by introducing the model-
ing and optimal design of some sample systems.
Industrial Electrochemistry could be an good com-
plement to a text such as Newman's Electrochemical
Systems in an advanced graduate course.
Industrial Electrochemistry would be an excel-
lent textbook for an upper-level undergraduate sur-
vey course on applied electrochemical technology. 0

Coming Up for Air
No matter where you do your graduate work,
your nose will be in your books and your mind on
your research. But at Clemson University, there's
something for you when you can stretch out for a
7% Like breathing good air. Or swimming, fishing,
30 sailing, and water skiing in the clean lakes. Or
hiking in the nearby Blue Ridge Mountains. Or
driving to South Carolina's famous beaches for a
weekend. Something that can really relax you.
All this and a top-notch Chemical Engineering
Department, too.
With active research and teaching in polymer
processing, composite materials, process automa-
tion, thermodynamics, catalysis, and membrane
applications what more do you need?

What do graduate students say about

the University of Houston

Department of Chemical Engineering?
"Houston is a university on the move. The chemical engineering department is ranked
among the top ten schools, and you can work in the specialty of your choice: semiconductor
processing, biochemical engineering, the traditional areas. The choice of advisor is yours, too,
and you're given enough time to make the right decision. You can see your advisor almost any
time you want to because the student-to-teacher ratio is low.
Houston is the center of the petrochemical industry, which puts the 'real world' of
research within reach. And Houston is one of the few schools with a major research program
in superconductivity.
The UH campus is really nice, and city life is just 15 minutes away for concerts, plays,
nightclubs, professional sports-everything. Galveston beach is just 40 minutes away.
"The faculty are dedicated and always friendly. People work hard here, but there is time
for intramural sports and Friday night get togethers"
If you'd like to be part of this team, let us hear from you.

"It's great!"
