Abstract

In this paper, we develop a mathematical model which calculates the temperature and the thermal contact resistance distributions in a multilayer media. This work is composed of two parts: The first part concerns the analytical solution of the conduction thermal problem for two plates, which ended in mathematical expressions giving the temperatures and the thermal resistance profiles. A computer code, which calculates the analytical expressions from the values of the temperature at any time as well as the thermal contact resistance, is elaborated in the second part.
