| 摘 要： | 用数值模拟的方法，将填充了相变材料球的蓄热槽内部划分为蓄热体和热媒体两个计算区域，分别建立数学模型，解决了两区求解时互为条件的耦合问题，并应用焓法计算蓄热体内部的相变过程，得出了与国外实验结果吻合的结果。

| Abstract: | By dividing the interior part of a heat storage tank filled with sphere-typed phase change material into two different regions,i.e.heat-storage units region and fluids media region,establishes mumerical model in the two regions,solves the question that the two regions provide conditions indispensable in calculating process for each other,and adopts enthalpy method to calculate the phase change process in the heat storage units region.The derived results are in good accordance with data from foreign experiments. |
