Numerical Simulation and Analysis Of PCM on Phase Change Process Consider Natural Convection Influence

摘要：

　　A phenomenon of heat energy storage and release in phase change materials (PCM) which used in building retaining structure has been investigated.In the reality process of phase change,liquid phase has two ways of heat exchange:pure heat conduction and natural convection.To analyze the reality melting and solidification of PCM,set up the PCM heat transfer model which considering liquid-phase natural convection in this paper and exploit CFD software to carry out numerical simulation.The result shows that the influence of natural convection has mainly something about circumfluence generated by liquid phase,the direction of circumfluence which is opposite when heat and cool,the circumfluence intensity enhances as the height of phase interface increase.
