## Description

**The long-awaited 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 semi-infinite 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
- One-dimensional composite medium
- Moving heat source problems
- Phase-change problems
- Approximate analytic methods
- Integral-transform 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.
