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.

Book Description
The theory of hydrodynamic stability for infinitesimal disturbances is applied to the steady symmetric annular flow of two incompressible fluids in a vertical pipe. The resulting 12 x 12 complex determinant for the determination of curves of neutral stability is reduced, by suitable approximations, to an 8 x 8 one, and numerical methods are used to determine some ne * utral curves for air-water mixtures.(Author).

Book Description
Excerpt from Stability of Two-Phase Annular Flow in a Vertical Pipe Because of its importance in many engineering applications fluid transport, heat exchangers), two-phase flow in tubes and orifices has received a great deal of attention in the last decade. But because the flow is very complex, even in straight vertical pipes, most of the effort has been devoted to accumulating a large quantity of experimental information, and to attempting to correlate data in particular cases with theories based on empirical relations. Furthermore, most of the work deals with the apparently simple (though important) case of annular flow without heat transfer or phase exchange; yet the results to date for this case are theoretically unsatisfactory and of modest practical utility. It is not the aim of this paper to correct this situation, but merely to apply the theory of hydrodynamic stability to this simple case in a more general way than has been used heretofore in this area. The stability theory has a record of significant (though not uniform) success. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
