Abstract

In this paper, a reduced order model of latent heat thermal energy storage (LHTES) containing spherical capsules filled with phase change material (PCM) is presented. The numerical method is based on the two-temperature non-equilibrium energy equations for heat transfer fluid (HTF) and PCM coupled with the enthalpy method to account for phase change in PCM. The numerical model is validated with the experimental results reported in the literature. The effects of porosity, capsule diameter, and capsule thickness on the temperature of HTF at the outlet of LHTES for charging period are studied. It is found that the stabilization time can be increased with low porosity and low mass flow rate, whereas the capsule shell thickness negligibly influences the heat transfer process from HTF to PCM.
