摘 要: | 对水平矩形腔内相变材料的接触熔化过程进行了研究.矩形腔的长度可以小于、大于宽度,且在底面保持恒温对相变材料加热.通过边界层理论分析,求得了传热过程的熔化规律与液体边界层厚度,并与实验数据进行了比较,讨论了矩形长度对它们的影响,给出有益的结论.

Abstract: | The melting process of phase change materials (PCM) inside a finite length rectangular capsule which is heated isothermally at the bottom is analyzed.By the film theory the melting phenomena and the thickness of the layer are obtained.The effects of the length of the capsule on the melting are discussed.Comparing the theoretical results with the experimental data,some useful conclusions are drawn. |
