This paper presents an original method: (i) to estimate thermophysical properties (heat capacity C and thermal condictivity K) and (ii) to experimentally validate heat source estimations. The method, called Thermal Field Measurements (TFM), is based on infrared thermal observations during cooling experiments in a same experimental setup. Results obtained with this method are in good agreement with other resutls published in literature. Only the homogeneous case is presented in this paper but a 1D heterogeneous case will also be presented in the conference.
