Abstract

The current context is for the development of renewable energies. These energies are often intermittent and require storage systems in particular for heat. Peritectic materials are excellent candidates for heat storage. They are suitable for a reversible chemical reaction near the time of a reversible solid-liquid phase transformation. Classic differential scanning calorimetry methods turn out being insufficient to characterize such materials. One of the reasons is related to the ignorance of the local heterogeneities and to the non-uniform distribution of the source terms of phase change when the material does not behave as a pure substance. It is therefore proposed here to develop methods consisting in measuring the temperature field evolution of these kinds of materials in the vicinity of the phase change phenomenon, by using the IR thermography. Some preliminary results are here presented.
