Principles of Heat Transfer in Porous Media


Book Description

Although the empirical treatment of fluid flow and heat transfer in porous media is over a century old, only in the last three decades has the transport in these heterogeneous systems been addressed in detail. So far, single-phase flows in porous media have been treated or at least formulated satisfactorily, while the subject of two-phase flow and the related heat-transfer in porous media is still in its infancy. This book identifies the principles of transport in porous media and compares the avalaible predictions based on theoretical treatments of various transport mechanisms with the existing experimental results. The theoretical treatment is based on the volume-averaging of the momentum and energy equations with the closure conditions necessary for obtaining solutions. While emphasizing a basic understanding of heat transfer in porous media, this book does not ignore the need for predictive tools; whenever a rigorous theoretical treatment of a phenomena is not avaliable, semi-empirical and empirical treatments are given.




Principles of Heat Transfer in Porous Media


Book Description

Convective heat tranfer is the result of fluid flowing between objects of different temperatures. Thus it may be the objective of a process (as in refrigeration) or it may be an incidental aspect of other processes. This monograph reviews in a concise and unified manner recent contributions to the principles of convective heat transfer for single- and multi-phase systems: It summarizes the role of the fundamental mechanism, discusses the governing differential equations, describes approximation schemes and phenomenological models, and examines their solutions and applications. After a review of the basic physics and thermodynamics, the book divides the subject into three parts. Part 1 deals with single-medium transfer, specifically with intraphase transfers in single-phase flows and with intramedium transfers in two-phase flows. Part 2 deals with fluid-solid transfer processes, both in cases where the interface is small and in cases where it is large, as well as liquid-liquid transfer processes. Part 3 considers three media, addressing both liquid-solid-solid and gas-liquid-solid systems.

Heat and Mass Transfer in Porous Media


Book Description

Recent developments in the theoretical and practical problems of porous media physics are reviewed in this volume. The main emphasis is on the interdisciplinary nature of transport phenomena in porous media study. State-of-the-art reviews and descriptions of innovative research in progress are reported. A broad spectrum of problems and techniques related to porous media physics is presented. Fundamental questions currently under investigation provide a unifying theme in this volume, helping the reader to understand the problems and research trends in the field. The first part focuses on general problems and techniques. Phenomenological aspects of averaging techniques, the hierarchy of scales that are involved in real porous media and the related scaling problems of multiphase, multicomponent transport phenomena are examined with the emphasis on providing the basic scientific background for a variety of applications. Sometimes, theory comes very close to applications, and occasionally they diverge. This timely treatise demonstrates that both is now the case in porous media physics. This volume will prove an indispensable reference source for all those interested in resolving discrepancies through innovative research work, and inspiring new advances in the field.
