8.1 HEAT TRANSFER OVERVIEW
Heat is an important and common type of energy, generally called thermal energy. Heat is defined as the energy given up by the elemental particles, such as atoms, molecules, or free electrons from the hotter regions of a body to those in cooler regions. In heat transfer, the flow of heat is studied. There are three modes of heat transfer, namely, conduction, convection, and radiation. Readers who are interested in detailed discussions on general heat transfer are referred to consult with the reference texts by Özisik , Carslaw and Jaeger , Kays and Crawford , and Incropera et al. .
