CFD Simulation on the Phase Change Storage Energy Materials

This paper studied a phase change process of phase change material (PCM) application building energy storage by CFD software. Set up the phase change process physics model consideration natural convection, the phenomenon of heat transfer from phase change and the impact of rules have been discussed, the proportion of solid and liquid of the process of phase change, the time of phase change, the interface of phase change and motion temperature image of liquid-region carried out numerical simulation. The results show that the natural convection generates the circumfluence at the liquid state of the phase change process, it takes on the role of accelerating the melt and reducing the solidification.
