The aim of this article is to identify by an inverse method the thermophysical properties of this composite material and all the parameters that are needed to build a physical model able to simulate the thermal behavior of a material containing PCM with accuracy. This approach consist in estimating different parameters that take place in the analytical relation of the enthalpy as a function of the temperature (h(T)) by comparing the response of the model with experimental results (here, heat flux measurement). A simplex algorithm allowed to minimize the quadratic criterion associated. The results obtained by inverse method are then analyzed and compared by experimental results obtained by direct method.Show less >
