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.

Book Description
The aim of this study was to investigate hydrodynamic two -phase (namelywater and air) fluid flow characteristics in helical pipes of low amplitude andstraight pipes of the same internal-diameter and constructional material: theresults for the two pipes have then been compared. One of the objectives was to measure pressure, pressure drop and liquidholdup in the two pipes. These are universal dominant parameters in the oiland-gas industry as they significantly impact on the exploitation andconveyance of crude oil from wells or reservoirs to the process plant, where thecrude is refined. The second objective was to examine applications of thehelical pipe. Experiments were performed on three different helical pipes of internaldiameters 25.4 mm, 50 mm and 100 mm and their straight counterparts. Thesingle-phase preliminary experimental results from the 25.4 mm internaldiameterfor both pipes have shown that both pressure and pressure drop arehigher in the helical pipe than in the straight pipe. The friction factors were alsoevaluated for both pipes and found to be higher in the helical pipe than in thestraight pipe. The single-phase and two-phase experimental results for the 50mm internal-diameter pipes confirmed the conclusions from the preliminaryexperimental results. The two-phase results showed that slug flow occurred inthe straight pipe at certain superficial velocities of air and water, whereas at thesame superficial velocities of air and water, slug flow did not ensue in the helicalpipe - instead bubbly flow was observed. Stratified flow occurred in the straightpipe at very low superficial velocities of air and water but under these sameconditions, bubbly flow ensued in the helical pipe. A section of 100 mm internal-diameter helical pipe was installed at somedistance from a catenary-shaped riser, with a view to investigating theeffectiveness of the helical pipe in mitigating severe slugging. The resultsshowed promise as the section of the helical pipe proved to be successful inreducing the menace of severe slugging. This novel finding is regarded as abreakthrough for the oil-and-gas industry in this respect. This is becausehydrocarbon proven reserves in the off-shore (i.e. deep sea-water) environmenthave been estimated to be close to 60%. All previous research studies over thepast decade to provide solution to the problem posed by severe slugging havenot yielded any appreciable results. This discovery also has the advantages ofreducing the demand on the topside (process) facility and the achievement ofstability of liquid production is resulted from the consequent flow assurance inthe pipeline and riser.

Book Description
Annular Two-Phase Flow presents the wide range of industrial applications of annular two-phase flow regimes. This book discusses the fluid dynamics and heat transfer aspects of the flow pattern. Organized into 12 chapters, this book begins with an overview of the classification of the various types of interface distribution observed in practice. This text then examines the various regimes of two-phase flow with emphasis on the regions of occurrence of the annular flow regime. Other chapters consider the single momentum and energy balances, which illustrate the differences and analogies between single- and two-phase flows. This book discusses as well the simple modes for annular flow with consideration to the calculation of the profile of shear stress in the liquid film. The final chapter deals with the techniques that are developed for the measurement of flow pattern, entrainment, and film thickness. This book is a valuable resource for chemical engineers.
