利用焓法求解了有三个分散凸起热源的矩形空腔内的熔化问题，并把计算结果与前人的实验结果进行了比较。计算和实验结果都显示，矩形空腔内的分散凸起热源对工质的熔化界面形状有显著的影响。
The enthalpy method is used to solve the problem of melting in a rectangular cavity with three scattered heat sources. The calculation results are compared with those of previous experiments. The calculation and experimental results show that the scattered convex heat source in the rectangular cavity has a significant effect on the shape of the melting interface of the working fluid.
