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.

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 Book Edition: 1. Domain 1 is comprised of the actual two-phase flow, and used to explore interfacial structure and eddy diffusivity.

Because the mean velocity of the gas flow is much greater than that of the liquid, the liquid layer serves essentially as a solid wavy wall as far as the gas flow is by: 5. Two-phase flow of cryogenic propellants in feed lines during the chill-down operation for space application system is inevitable.

Such cooling process exhibits dynamic response, which are difficult to control due to flow instabilities and differential cooling rates. Moreover, the dynamics of two-phase phenomena in microgravity differ from that operated at terrestrial gravity. Physical models of interfacial waves are presented for vertical upward flow (+1g), vertical downward flow (−1g), and microgravity (μg), at different gas and liquid flow rates.

Based on these studies, the predominant parameters and the features of the wave structure are : Zhaolin Wang, Kamiel S. Gabriel, Zhenfeng Zhu. A basic understanding of various hydrodynamic phenomena in annular two-phase is essential to develop mechanistic model for the prediction dryout.

The major objective of this investigation was to perform experimental and theoretical analysis of the important hydrodynamic phenomena such as droplet entrainment, droplet deposition, and liquid film interfacial waves in vertical annular two-phase flow.

In two-phase flow modeling, it is essential to take into account the interfacial forces including the drag force, lift force, wall lubrication force and turbulent dispersion force.

In this study, the air–water two-phase flow distribution characteristics in a vertical upward annular channel were studied : Xiu Xiao, Yu Guo, Minyi Xu, Yulong Ji, Qingzi Zhu, Qingzi Zhu, Mamoru Ishii.

A simple theory for annular two-phase flow is developed in terms of equations for the interfacial and wall shear stresses. Expressions for the pressure drop and void fraction are derived. The interfacial area transport of vertical, upward, air–water two-phase flows in an annular channel has been investigated at different system pressures.

The inner and outer diameters of the annular channel were mm and mm, respectively. Twenty three inlet flow conditions were selected, which covered bubbly, cap-bubbly, and churn-turbulent by: 4.

This book is an undertaking of a pioneering work of uniting three vast fields of interfacial phenomena, rheology and fluid mechanics within the framework of solid-liquid two phase flow. No wonder, much finer books will be written in the future as the visionary aims of many nations in combining molecular chemistry, biology, transport and.

G Cited by: Interfacial Phenomena, Fall taught by Prof. John W. Bush June 3, Annular Two-Phase Flow Fart 1: A Simple Theory A simple theory for annular two-phase flow is developed in terms of equations for the interfacial and wall shear stresses.

Expressions for the pressure drop and void fraction are derived. Criteria for the minim-urn, pressure drop, zero wall shear, and flow regime transition in vertical flow are given.

A flow pattern, which appears in many industrial applications, is annular two-phase flow. Its main characteristic is that the main portion of the liquid mass is located at the walls of the tube forming an annulus, while the gas phase flows through the annulus core dragging small liquid : Yago Rivera, José-Luis Muñoz-Cobo, César Berna, José-Luis Cuadros, Alberto Escrivá.
