Title

Performance Evaluation Of A Solid State Phase Change Material For Thermal Storage Applications

Abstract

A numerical model was developed to predict the heat transfer characteristics of a material undergoing a solid state phase change. The computer program consists of a time-dependent finite-differencing scheme applied to a vertical solid cylinder. Heat transfer to or from the solid is by means of radiation and natural or forced convection. Variance in material properties with temperature and phase are addressed. Computer results were compared to experimental data to verify the program. Experiments were performed on pentaerythritol being cooled through phase transition. Results show a good correlation between theory and experiment, despite uncertainty with respect to the thermophysical properties of the material. A major source of uncertainty is the presence of voids within the cast solid, which substantially reduces the solid's density and conductivity.
