Název v původním jazyce

Fitting of heat capacity peaks of PCMs with a theoretical formula

Popis výsledku v původním jazyce

We introduce an explicit theoretical formula for the heat capacity peaks that occur in materials during phase changes. Such materials are of importance in many applications where thermal energy storage is needed, including solar systems, buildings, electronic devices, or radionuclide encasements. We show how theoretical parameters that appear in the formula can be adjusted in order to fit experimentally measured peaks. Two of these parameters are interesting in applications: the specific latent heat and phase change temperature. We illustrate this procedure for four peaks associated with phase changes in four different materials for which the heat capacity peaks had been measured at slow heating rates.
