Abstract: Gas liquid two phase flow are encountered in various processing fields particularly in oil and gas industry. In production tubing and casing design for an oil well, optimization of operating conditions, and economic design, consideration is always given to physical properties on the slug flow because of the liquid phase intermittency along the pipe. Therefore for effective and optimal design performance, it is important to obtain accurately the effects of system properties on the mechanisms responsible for slug flow. This is addressed here with observations and measurements being reported. Two advanced wire mesh sensors (WMS), developed at Forschungszentrum Rossendorf-Dresden, Germany, have been employed on a vertical 67 mm diameter pipe employing air/water and air/silicone oil mixtures in upward flow. This enables an examination of the flow to be carried out at several levels of complexity. Both measuring sensors provide time and cross-sectionally resolved information about the spatial distribution of the phases. Further analysis of the data also yields data of the frequency of periodic structures within the flow. For time series taken at conditions corresponding to slug flow, Taylor bubble and liquid slug void fraction have been calculated. Then, the velocities of individual Taylor bubble are obtained by cross-correlating signals from two planes of ECT in case of air silicone oil and two capacitance probe for the air water experiments. The distributions of lengths of Taylor bubbles and liquid slugs are presented.
General Note: The International Conference on Multiphase Flow (ICMF) first was held in Tsukuba, Japan in 1991 and the second ICMF took place in Kyoto, Japan in 1995. During this conference, it was decided to establish an International Governing Board which oversees the major aspects of the conference and makes decisions about future conference locations. Due to the great importance of the field, it was furthermore decided to hold the conference every three years successively in Asia including Australia, Europe including Africa, Russia and the Near East and America. Hence, ICMF 1998 was held in Lyon, France, ICMF 2001 in New Orleans, USA, ICMF 2004 in Yokohama, Japan, and ICMF 2007 in Leipzig, Germany. ICMF-2010 is devoted to all aspects of Multiphase Flow. Researchers from all over the world gathered in order to introduce their recent advances in the field and thereby promote the exchange of new ideas, results and techniques. The conference is a key event in Multiphase Flow and supports the advancement of science in this very important field. The major research topics relevant for the conference are as follows: Bio-Fluid Dynamics; Boiling; Bubbly Flows; Cavitation; Colloidal and Suspension Dynamics; Collision, Agglomeration and Breakup; Computational Techniques for Multiphase Flows; Droplet Flows; Environmental and Geophysical Flows; Experimental Methods for Multiphase Flows; Fluidized and Circulating Fluidized Beds; Fluid Structure Interactions; Granular Media; Industrial Applications; Instabilities; Interfacial Flows; Micro and Nano-Scale Multiphase Flows; Microgravity in Two-Phase Flow; Multiphase Flows with Heat and Mass Transfer; Non-Newtonian Multiphase Flows; Particle-Laden Flows; Particle, Bubble and Drop Dynamics; Reactive Multiphase Flows
