摘要
对矩形腔内相变材料紧密接触熔化过程进行了理论分析。应用努谢尔特液体边界层理论,求得了便于工程计算用的接触熔化传热过程的理论解。分析结果与实验数据进行了比较,吻合程度良好。
Close-contact melting process of phase change materials (PCM) inside horizontal rectangular capsules is theoretically analysed. The capsules are heated isothermally and the aspect ratio of PCM inside capsule can be changed. Applying Nusselt's liquid film theory to the contact melting heat transfer process, we obtain the theoretical formulas convenient to engineering calculation. The analytical results show good agreement with the related experimental data.
