A much-needed reference focusing on the theory, design, and applications of a broad range of surface types. * Written by three of the best-known experts in the field. * Covers compact heat exchangers, periodic heat flow, boiling off finned surfaces, and other essential topics.
The book covers various topics of heat transfer. It explains and analyzes several techniques and modes of heat transfer such as conduction in stationary media, convection in moving media and also by radiation. It is primarily a text book useful for undergraduate and postgraduate students. The book should also interest practicing engineers who wish to refresh their knowledge in the field. The book presents the various topics in a systematic way starting from first principles. The topics are developed to a fairly advanced level towards the end of each chapter. Several worked examples illustrate the engineering applications of the basic modeling tools developed in the text. The exercises at the end of the book are arranged chapter wise and challenge the reader to tackle typical real-life problems in heat transfer. This book will be of potential use for students of mechanical engineering, chemical engineering and metallurgy in most engineering colleges.
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."
