The melting process of alloy phase change material in a rectangular under temperature difference is simulated by CFD software. The simulation model is verified by the experimental result. The impacts of the natural convection on the solid-liquid interface, the temperature and the circulation speed in the melting process are analyzed. The results show that the phase change material in rectangular should to be heated from the two sides and the bottom in order to reduce heat transfer resistance and get a faster melting speed.
