Abstract

Simulation model of phase change thermal storage canisters was built under microgravity condition. Void distribution model was built based on simulation result of solidification process in canister, and simulation of phase change thermal storage process in canisters with that void model was carried out. Simulation results were analyzed and compared with that of other two void models, which were neglecting void distribution or simply assuming void as a ring close to outer wall of canisters, respectively. Effects of void distribution on solid-liquid phase change thermal storage were testified. The simulation results are improved by setting up more real void model, and possess positive meaning in improving design of thermal storage canisters.
