Modeling of Heat Transfer

Summary

This chapter presents a reminder of courses on heat transfer limited to what is necessary to understand and masters the methods of measuring the thermal properties of materials. It discusses the main quantities involved in solving a heat transfer problem. The chapter considers the heat transfer between a solid and a fluid, the energy being transmitted by the fluid's displacement. It describes the various characteristic quantities of a material that have appeared in the heat transfer equations. Conduction is the transfer of heat within an opaque medium, without displacement of matter, under the influence of a temperature difference. The transfer of heat via conduction within a body takes place according to two distinct mechanisms: transmission via atomic or molecular vibrations and transmission via free electrons. The chapter provides the parallel and series models, since the lowest possible value of the thermal conductivity is given by the series model and the highest by the parallel model.
