Book Description
An analysis of two-phase flow was performed. The model used considers the interfacial surface roughness and the relative velocity between the two phases. Expressions for the mean film thickness and the friction factor are obtained. Comparison of predicted film depths and friction coefficients with measured values shows agreement within the limits of the popular correlations. The agreement between theory and experiment is excellent when the experimental system approaches symmetry, a condition of the model. (Author).

Book Description
The investigation concerned the liquid distribution and surface character of the liquid when quantities of liquid and gas are flowing together in such proportions as to cause the liquid to flow in a thin film on the wall of the confining tube, i.e., annular two-phase flow. The data obtained disclosed that throughout much of the so-called annular pattern of horizontal two-phase flow a considerable eccentricity of the liquid exists due to gravity effects. At moderate gas rates and very low liquid flows, film symmetry is approached; at very high gas rate a good approach to symmetry is obtained regardless of the liquid rate. (Author).

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 static pressure drop and both the local and average heat transfer coefficients were measured for the horizontal annular flow of water and air in a tube with an inside diameter of one inch. A correlation for the heat transfer coefficients was obtained. The pressure drop data agreed well with the Lockhart-Martinelli correlation and the prediction of the Wrobel-McManus wave roughness theory. A theory based on an axisymmetric model with no liquid entrainment was developed to allow predictions of local heat transfer coefficients. In comparing the predictions with the measured coefficients, 85% of the predictions were within plus or minus 60% of the measured values from horizontal flow and substantially better agreement resulted when the theory was modified empirically to take into account liquid entrainment and circumferential temperature variations. The theory was applied to conditions beyond the scope of the experimental program to predict the effects of varying heat flux, tube temperature, and tube diameter on the coefficients.
