| 摘 要： | 采用实验的方法对相变材料融化过程中自然对流的影响进行了研究,获得了自然对流作用下的融化速率与平均Nusselt数的准则关系式。结果表明,与纯导热模型相比,自然对流作用加速了融化的进行,建立导热-对流耦合传热模型对于准确预测融化过程具有一定的必要性。

| Abstract: | Experimental method is employed to investigate the effect of natural convection on the melting process of phase change material(PCM)and the empirical correlations of melting fraction and average Nusselt number are obtained.The results indicate that natural convection enhances the melting process compared with the pure conduction model.The conduction-convection coupled model is necessary for predicting melting process exactly. |

| Keywords: | natural convection phase change melting heat transfer enhancement |
