摘　　要：利用计算流体力学软件FLUENT凝固/熔化模型对一种相变材料蓄冷球的凝固过程进行数值模拟研究,得到了在第一类边界条件下蓄冷球凝固过程的温度场分布、相界面移动规律,并分析了凝固时间与壁面温度和球径的关系。所得到的结论对相变问题的数值模拟以及相变蓄能装置的设计具有重要的参考价值。By using Solidification/Melting models of FLUENT software, the solidification process of a kind of phase-change material in cooling storage ball is numerically simulated. Considered the first kind of boundary condition, temperature field is obtained and phase change interface position changed with time is also calculated. In the meantime, the relationships between solidification time and wall temperature and ball diameter are analyzed. The results got here can provide good references for the numerical simulation of phase change problem and the design of phase change energy storage device.
