Modern Developments In Heat Transfer

Modern Developments in Heat Transfer provides information pertinent to heat transfer investigation, including convective heat transfer, radiation heat transfer, as well as heat and mass transfer. This book examines the aspects and properties of high temperature heat transfer. Organized into 14 chapters, this book starts with an overview of noncircular duct heat transfer in a wide range of engineering applications from automobile radiators to nuclear power plants. This text then examines the differences between circular and noncircular duct flows. Other chapters describe energy transport by radiation wherein photons, as energy carriers, are released from molecules of the radiating body and travel on straight lines until they are scattered or absorbed by other atoms or molecules. This book discusses as well the process of evaporation, which results in the conversion of a liquid into a vapor. The final chapter deals with plasma dynamics and its features. Physicists, chemists, mathematicians, and engineers will find this book extremely useful.

This volume covers the modern developments in boiling heat transfer and two-phase flow, and is intended to provide industrial, government and academic researchers with state-of-the-art research findings in the area of multiphase flow and heat transfer technology. Special attention is given to technology transfer, indicating how recent significant results may be used for practical applications. The chapters give detailed technical material that will be useful to engineers and scientists who work in the field of multiphase flow and heat transfer. The authors of all chapters are members of the CMR at Rensselaer, a research centre specializing in the state-of-the-art in multiphase science.

Heat Transfer is important in food processing. This edited book presents a review of ongoing activities in a broad perspective.

Descripción del editor: "This volume is concerned with the heat transfer from extended surfaces, such as fins attached to a primary transfer surface. These are used extensively within heat exchanges and on heat transfer equipment to ensure that a specified rate of heat transfer is achieved between a heat source and sink. All of the chapters come from invited contributors and follow a unified outline and presentation.Contents: Overview of Extended Surface Heat Transfer ââ,¬â€œ Fins; Coupled Forced Convection, Conduction and Thermal Radiation of a Rectangular Fin in a Confined Space; Mechanistic Investigation of the Performance of a Triangular Fin; Conjugate Free and Mixed Convection Heat Transfer from a Vertical Fin Embedded in a Porous Medium; About Fin Performance and Optimization; Two-Dimensional Effects in Extended Surface Assessment; Steady-State Heat Transfer and Performance Assessment; Multi-Louvred Fin Surfaces; Methodology for the Design of Multi-Stream Plate-Fin Heat Exchangers; Incorporation of a Consideration of Operability into the Design of Multi-Stream Heat Exchangers."

Containing papers presented at the twelfth in a series of successful international conferences on Advanced Computational Methods and Experiments in Heat Transfer, this book covers the latest developments in this important field. Heat Transfer plays a major role in emerging application fields such as sustainable development and the reduction of greenhouse gases, as well as micro- and nano-scale structures and bio-engineering. Typical applications include heat exchangers, gas turbine cooling, turbulent combustion and fires, electronics cooling, melting and solidification. The nature of heat transfer problems is complex, involving many different simultaneously occurring mechanisms (e.g., heat conduction, convection, turbulence, thermal radiation. phase change). Their complexity makes it imperative that we develop reliable and accurate computational methods to replace or complement expensive and time-consuming experimental trial and error work. Tremendous advances have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and more powerful computers capable of performing efficient and rapid calculations. Nevertheless, to further progress, it will also be necessary to develop theoretical and predictive computational procedures--both basic and innovative--and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. The book includes such topics as: Heat Transfer in Energy Producing Devices; Heat Transfer Enhancement; Heat Transfer Problems; Natural and Forced Convection and Radiation; Multiphase Flow Heat Transfer; Modelling and Experiments.

This book, "Heat and Mass Transfer in Porous Media", presents a set of new developments in the field of basic and applied research work on the physical and chemical aspects of heat and mass transfer phenomena in a porous medium domain, as well as related material properties and their measurements. The book contents include both theoretical and experimental developments, providing a self-contained major reference that is appealing to both the scientists and the engineers. At the same time, these topics will encounter of a variety of scientific and engineering disciplines, such as chemical, civil, agricultural, mechanical engineering, etc. The book is divided in several chapters that intend to be a short monograph in which the authors summarize the current state of knowledge for benefit of professionals.
