Web1 de set. de 2002 · In this paper we discuss the conduction of heat in solids excited by a periodically time-dependent source, commonly encountered in photothermal experiments. In the analysis, we take into account the relaxation time necessary for the onset of the heat flux which leads to a second time derivative in the heat diffusion equation. It is shown … WebTheory: The theory of heat transfer seeks to predict the energy transfer that may take place between material bodies as a result of temperature difference. ... In conduction, heat is carried by means of collisions between rapidly moving molecules closer to the hot end of a body of matter and the slower molecules closer to the cold end.
