摘要
以泡沫金属材料作为骨架,将相变储能材料注入其孔隙中构成复合相变材料作为研究对象。根据泡沫金属和相变材料的结构特点,利用ANSYS软件建立模型,将相变材料的潜热定义到材料的焓中,其中焓的数值随温度变化,再分别对泡沫金属复合相变材料和未含泡沫金属的相变材料进行相变传热过程的有限元仿真分析。结果表明,采用泡沫金属的复合相变材料的传热特性得到很大的改善,泡沫金属的使用增加了原有相变材料的传热速度,显著缩短了相变材料熔化和凝固的时间。ANSYS的便捷性和灵活的操作性,对研究较复杂的相变问题具有一定的参考意义。
The composite phase change material was constructed by pouring the phase change energy storage material into the high porosity metal foam structure. The composite phase change material model was established on the basis of their structure characteristics with ANSYS. Due to the value of enthalpy changed with temperature value, the phase change latent heat could define into the material’s enthalpy. Based on this, the finite element simulation analysis was built to study the phase heat transfer process of phase change material with metal foam and without metal foam. The results showed that the composite phase change material’s heat transfer characteristic was highly improved compared with the pure material. The using of metal foam increased the heat transfer speed with the pure phase change material, and the time of melt and solidification was greatly shortened. The convenience and flexible operation of ANSYS provided some reference for the study of complicated phase changeproblem.
