| 摘 要： | 建立了微重力下相变蓄热容器的仿真计算模型,根据蓄热容器内凝固过程的仿真结果建立了更加符合实际的空穴分布模型,对相变蓄热过程进行了仿真计算。对比分析了该文空穴模型与忽略空穴、简单空穴模型对应的仿真结果,证明空穴分布形式对于蓄热容器内的相变蓄热过程的显著影响。通过建立更加真实的空穴分布模型提高了相变蓄热过程仿真计算的准确性,对蓄热容器的设计改进具有积极的指导意义。

| 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 o... |
