"Conduction and Radiation" is concerned with discussion and problem-solving related to the two principal modes of heat transfer. The text includes special topics such as inverse and microscale heat transfer, phase change, diffusive mass transfer, spectral formulation of the enclosure theory, and a simplified analysis of the radiative transfer equation. Analytical and numerical treatments of the radiative transfer equation are presented. The goal of the text is to extract developments that have taken place over the past two decades and present them in a self-contained manner. The book provides a convenient link to students between a grossly simplified approach of the first level texts and sophisticated general purpose software packages. Much of the contents of the book can be covered in a one-semester course that combines both conduction and radiation. The book could be used for individual courses on conduction and radiation with supplementary material provided for numerical methods and measurement techniques. Apart from students in mechanical engineering, those from applied mechanics, energy technology, and chemical engineering are expected to benefit from its contents.
