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
Multi-phase flows are part of our natural environment such as tornadoes, typhoons, air and water pollution and volcanic activities as well as part of industrial technology such as power plants, combustion engines, propulsion systems, or chemical and biological industry. The industrial use of multi-phase systems requires analytical and numerical strategies for predicting their behavior. In its third extended edition this book contains theory, methods and practical experience for describing complex transient multi-phase processes in arbitrary geometrical configurations. This book provides a systematic presentation of the theory and practice of numerical multi-phase fluid dynamics. In the present second volume the mechanical and thermal interactions in multiphase dynamics are provided. This third edition includes various updates, extensions, improvements and corrections.

Book Description
Two new versions of the k-omega two-equation turbulence model will be presented. The new Baseline (BSL) model is designed to give results similar to those of the original k-omega model of Wilcox, but without its strong dependency on arbitrary freestream values. The BSL model is identical to the Wilcox model in the inner 50 percent of the boundary-layer but changes gradually to the high Reynolds number Jones-Launder k-epsilon model (in a k-omega formulation) towards the boundary-layer edge. The new model is also virtually identical to the Jones-Lauder model for free shear layers. The second version of the model is called Shear-Stress Transport (SST) model. It is based on the BSL model, but has the additional ability to account for the transport of the principal shear stress in adverse pressure gradient boundary-layers. The model is based on Bradshaw's assumption that the principal shear stress is proportional to the turbulent kinetic energy, which is introduced into the definition of the eddy-viscosity. Both models are tested for a large number of different flowfields. The results of the BSL model are similar to those of the original k-omega model, but without the undesirable freestream dependency. The predictions of the SST model are also independent of the freestream values and show excellent agreement with experimental data for adverse pressure gradient boundary-layer flows.

Book Description
Turbulence Phenomena provides an introduction to the eddy transfer of momentum, mass, and heat, specifically at interfaces. The approach of the discussion of the subject matter is based on the eddy mixing length concept of Prandtl. Chapter 1 begins with a discussion on basic concepts regarding liquid flow such as viscosity, turbulent flows, and velocities. As concepts and theories are established, the book then discusses the eddy transfer in fluids, specifically eddy transfer of mass and heat within fluids and eddy transfer near solid surfaces. The concept of eddies in different surfaces is discussed in length all throughout numerous chapters. These different surfaces include clean gas-liquid surfaces, clean liquid-liquid interfaces, and film-covered surfaces. The last few chapters focus on the more detailed discussion on turbulence, such as the concept of spontaneous interfacial turbulence and emulsification and turbulent dispersion and coalescence. The book will be of great use to undergraduate students of chemical engineering, physics, and chemistry.

Book Description
First U.K. National Conference on Heat Transfer, Volume 2, documents the proceedings of the conference organized by the U.K. National Committee for Heat Transfer—a joint committee of the Institutions of Chemical and Mechanical Engineers and includes a member nominated by the Heat Transfer Society—held at the University of Leeds, on 3-5 July 1984. It is intended that the Leeds conference will be the first of a series of UK National Conferences which will be held at four-yearly intervals (1984, 1988, 1992 etc). Thus, for people working in the heat transfer field there will be an opportunity to present and discuss their work at a major conference every two years. This volume contains 52 papers that were presented during Sessions 11-20. The papers in Session 11 deal with enhanced heat transfer. Session 12 presents studies on two-phase flow and boiling. Session 13 contains papers on natural convection. Session 14 focuses measurement techniques in heat transfer while Session 15 deals with heat transfer in high temperature systems. The presentations in Session 16 cover heat transfer in combustion systems while those in Session 17 focus on convective heat transfer. Session 18 takes up heat transfer in cross-flow. Session 19 discusses papers on applied heat transfer. Session 20 deals with studies on industrial heat exchangers.
