摘要
本文利用CFD软件对方腔内合金相变材料在温差作用下的熔化过程进行了数值模拟研究。通过与试验结果的比较,验证了本文采用的模型和算法的正确性。同时,详细研究了熔化过程中合金相变材料的固-液界面、温度及环流速度的变化规律。结果表明,为了减小传热热阻,加快合金的熔化速度,从方腔的侧面和底面加热相变材料时熔化效果最好。
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.
