Book Description
A IUTAM symposium on "Measuring Techniques in Gas-Liquid Two Phase Flows" was held on July 5-8, 1983 in Nancy, France. This topic in cluded instrumentation for steam-water and liquid-vapor flows but strictly excluded measuring techniques for gas or liquid flows with solid particles. The top priority in the paper selection was given to presentations of new methods which had been substantiated by theoretical modeling, calibration tests and comparison tests with other techniques. Examples of experimental resul ts obtained with the proposed instrumentation had to be displayed. However the interpretation of these results in terms of two-phase flow or heat transfer modeling did not fall wi thin the scope of the meeting. Thirty four papers were presented during the Symposium and 79 participants coming from Canada, European countries, Japan and the United States attended the sessions. They represented not only Universities but also state agencies and private companies. After the meeting each paper was peer-reviewed by at least three referees. The Editors of this Procee dings Volume are pleased to extend their deep gratitude to the following reviewers: J.L. Achard, R.J. Adrian, B. Azzopardi, J.A. Boure, G. Costigan, M. Courtaud, A.E. Dukler, F. Durst, J.R. Fincke, G. Gouesbet, P. Griffith, T.J. Hanratty, A. Hawighorst, T.R. Heidrick, G. Hetsroni, Y.Y. Hsu, M.

Book Description
The flow pattern generated in pipes for two-phase gas-liquid horizontal flows can significantly affect the efficiency of chemical process equipment. Since the early 1900's, scientists and engineers have investigated various methods for characterizing the flow patterns generated for various two-phase chemical systems. A notable effort was made by Baker to quantify physical fluid properties and correlate them to observed flow patterns in pipe flow. The primary objective of this research was to develop a flow pattern recognition system, for industrial implementation, that is suitable for characterizing transient two-phase flow patterns. Since the advent of computer and system control equipment, researchers have focused on quantifying flow characteristics by analyzing pressure fluctuation because the natural tendency of multiphase flow is to pulse as the fluid phases mix while moving along the pipe length. Recent developments in digital signal processing provide new methods for characterizing transient signals. A novel approach using wavelet transform analysis to study pressure fluctuations in two-phase flow systems has been developed in this research. Experimental development includes the design of a baseline system and a flow pattern recognition system. (Abstract shortened by UMI.).
Two-Phase Gas-Liquid Flow in Pipes with Different Orientations

Book Description
This book provides design engineers using gas-liquid two-phase flow in different industrial applications the necessary fundamental understanding of the two-phase flow variables. Two-phase flow literature reports a plethora of correlations for determination of flow patterns, void fraction, two- phase pressure drop and non-boiling heat transfer correlations. However, the validity of a majority of these correlations is restricted over a narrow range of two -phase flow conditions. Consequently, it is quite a challenging task for the end user to select an appropriate correlation/model for the type of two-phase flow under consideration. Selection of a correct correlation also requires some fundamental understanding of the two-phase flow physics and the underlying principles/assumptions/limitations associated with these correlations. Thus, it is of significant interest for a design engineer to have knowledge of the flow patterns and their transitions and their influence on two-phase flow variables. To address some of these issues and facilitate selection of appropriate two-phase flow models, this volume presents a succinct review of the flow patterns, void fraction, pressure drop and non-boiling heat transfer phenomenon and recommend some of the well scrutinized modeling techniques.
