Computer aided engineering has become a key component of thermal engineering. This book provides a concise overview of computational methods used in thermal analysis. The first three sections of the text present computational techniques for conduction, radiation, and convection. Each section reviews the relevant physical phenomena and their governing equations and then discusses the predominant computational techniques used in the industry. The final section of the text illustrates how the numerical methods for the different mechanisms of heat transfer can be combined to model a thermal system. The author also addresses the inherent multiphysics nature of thermal analysis.
