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.

Book Description
Studies of fluid flow and heat transfer in a porous medium have been the subject of continuous interest for the past several decades because of the wide range of applications, such as geothermal systems, drying technologies, production of thermal isolators, control of pollutant spread in groundwater, insulation of buildings, solar power collectors, design of nuclear reactors, and compact heat exchangers, etc. There are several models for simulating porous media such as the Darcy model, Non-Darcy model, and non-equilibrium model. In porous media applications, such as the environmental impact of buried nuclear heat-generating waste, chemical reactors, thermal energy transport/storage systems, the cooling of electronic devices, etc., a temperature discrepancy between the solid matrix and the saturating fluid has been observed and recognized.

Book Description
This book provides research on theories, properties and applications of porous media. Chapter One considers non-standard models of multi-component adsorption with applications to gas adsorption processes in coalbeds. Chapter Two discusses the influence of temperature dependent thermal conductivity on non-darcy flow and heat transfer in a vertical rectangular duct. Chapter Three investigates the effects of different modes of evaporation on the time-dependent wicking behavior of liquids into a porous strip. Chapter Four deals with the study of dispersion of a solute for porous medium in a vertical double-passage channel with first order chemical reaction. Chapter Five investigates the effect of partial slip viscous flow over a stretching sheet with suction/injection in a porous medium. In Chapter Six, the onset of nanofluid convection in a Walters B fluid-saturated horizontal porous layer is studied.

Book Description
The rapid growth of literature on convective heat and mass transfer through porous media has brought both engineering and fundamental knowledge to a new state of completeness and depth. Additionally, several new questions of fundamental merit have arisen in several areas which bear direct relation to further advancement of basic knowledge and applications in this field. For example, the growth of fundamental heat transfer data and correlations for engineering use for saturated media has now reached the point where the relations for heat transfer coefficients and flow parameters are known well enough for design purposes. Multiple flow field regimes in natural convection have been identified in several important enclosure geometries. New questions have arisen on the nature of equations being used in theoretical studies, i. e. , the Validity of Darcy assumption is being brought into question; Wall effects in high and low velocity flow fields have been found to play a role in predicting transport coefficients; The formulation of transport problems in fractured media are being investigated as both an extension of those in a homogeneous medium and for application in engineering systems in geologic media and problems on saturated media are being addressed to determine their proper formulation and solution. The long standing problem of how to adequately formulate and solve problems of multi-phase heat and mass transfer in heterogeneous media is important in the technologies of chemical reactor engineering and enhanced oil recovery.
