This thesis presents experimental studies relating to gas-liquid slug flows in horizontal and near-horizontal pipelines. In such flows, liquid-continuous regions ("slugs") pass along the pipe separated by regions of stratified flow ("elongated bubbles") (see Chapter 1). Gas may be entrained at the slug fronts and is subsequently discharged into the elongated bubble at the slug tail. The focus of the work described in this thesis is on this gas entrainment process. Specifically, the aim is to make objective measurements of the slug front gas entrainment rate. A review of the earlier work (see Chapter 2) showed a large diversity of results for slug front gas entrainment. This reflects the difficulty of doing objective experiments on this important parameter. In the work described here, two new techniques for determining gas entrainment rate were implemented and investigated, namely the three-way valve method and the bubble shrinkage method. All of the experiments described in this thesis were with air-water flows at near atmospheric pressure, though the techniques developed could be applied to other fluid pairs and to different pressures. The three-way valve method involves diverting a slug front to pass over a stratified liquid layer and to determine the gas pick-up rate at the slug front from the slug front propagation velocity. The experiments were carried out for a 32.8 mm pipe in the LOTUS facility (described in Chapter 3) and for a 78 mm pipe using the WASP facility (also described in Chapter 3). The experimental results are presented in Chapters 4 and 5 respectively and show that the gas entrainment rate per unit film width is similar for the two diameters and depends on the relative velocity between the slug front and the liquid film ahead of it. The results indicate entrainment rates which are within the range previously measured but which are above those calculated from the existing correlations. A new correlation for prediction of gas entrainment in slug flow in horizontal pipes was developed which adequately predicts previous gas entrainment work (repeated here using LOTUS facility). In the bubble shrinkage method, the aim is to measure the shrinkage rate (and hence the rate of loss of gas by entrainment) of an elongated bubble passing along a pipe in a liquid flow. Development work on this method is described in Chapter 6 and (though the test section lengths were not sufficient to measure shrinkage accurately), it could be deduced (from measurements of the slug front (bubble tail) velocity) that the results were consistent with the three-way valve experiments. The actual phenomena accompanying gas entrainment at the slug front in slug flow are extremely complex and this was demonstrated with high speed video photography using an Olympus i-SPEED 3 system (see Chapter 7). Depending on the actual conditions, the advancing slug front could be attached to or detached from the preceding liquid layer. There were significant differences in the phenomena observed depending on the nature of the preceding liquid layer (stratified flow, descending liquid film, and stationary liquid film).

Slurry Flow: Principles and Practice describes the basic concepts and methods for understanding and designing slurry flow systems, in-plan installations, and long-distance transportation systems. The goal of this book is to enable the design or plant engineer to derive the maximum benefit from a limited amount of test data and to generalize operating experience to new situations. Design procedures are described in detail and are accompanied by illustrative examples needed by engineers with little or no previous experience in slurry transport. The technical literature in this field is extensive: this book facilitates its use by surveying current research results and providing explanations of mechanistic flow models. This discussion of background scientific principles helps the practitioner to better interpret test data, select pumps, specify materials of construction, and choose measuring devises for slurry transport systems. The extensive range of topics covered in Slurry Flow: Principles and practice includes slurry rheology, homogeneous and heterogeneous slurry flow principles, wear mechanisms, pumping equipment, instrumentation, and operating aspects.

This is an up-to-date review of recent advances in the study of two-phase flows, with focus on gas-liquid flows, liquid-liquid flows, and particle transport in turbulent flows. The book is divided into several chapters, which after introducing basic concepts lead the reader through a more complex treatment of the subjects. The reader will find an extensive review of both the older and the more recent literature, with abundance of formulas, correlations, graphs and tables. A comprehensive (though non exhaustive) list of bibliographic references is provided at the end of each chapter. The volume is especially indicated for researchers who would like to carry out experimental, theoretical or computational work on two-phase flows, as well as for professionals who wish to learn more about this topic.

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.
