Identification of Thermal Properties and Thermodynamic Model for a Cement Mortar Containing PCM by Using Inverse Method
Abstract : The support of this study is a cement mortar containing a micro-encapsulated phase change material (PCM). 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.
