The longawaited revision of the bestseller on heat conduction
Heat Conduction, Third Edition is an update of the classic text on heat conduction, replacing some of the coverage of numerical methods with content on micro and nanoscale heat transfer. With an emphasis on the mathematics and underlying physics, this new edition has considerable depth and analytical rigor, providing a systematic framework for each solution scheme with attention to boundary conditions and energy conservation. Chapter coverage includes:
 Heat conduction fundamentals
 Orthogonal functions, boundary value problems, and the Fourier Series
 The separation of variables in the rectangular coordinate system
 The separation of variables in the cylindrical coordinate system
 The separation of variables in the spherical coordinate system
 Solution of the heat equation for semiinfinite and infinite domains
 The use of Duhamel's theorem
 The use of Green's function for solution of heat conduction
 The use of the Laplace transform
 Onedimensional composite medium
 Moving heat source problems
 Phasechange problems
 Approximate analytic methods
 Integraltransform technique
 Heat conduction in anisotropic solids
 Introduction to microscale heat conduction
In addition, new capstone examples are included in this edition and extensive problems, cases, and examples have been thoroughly updated. A solutions manual is also available.
Heat Conduction is appropriate reading for students in mainstream courses of conduction heat transfer, students in mechanical engineering, and engineers in research and design functions throughout industry.
