利用移动热源法对相变材料在球壳内的凝固与熔化过程进行理论分析 ,得出不同工况条件下相变热量与相变界面随时间变化规律。与有机混合相变材料实验结果对比表明 ,该理论分析对实际相变过程有很好的预见性。
Using the mobile heat source method, the phase transformation material solidification and melting process in the spherical shell were theoretically analyzed, and the variation law of phase transition heat transfer and phase change interface with time under different working conditions was obtained. Compared with the experimental results of organic mixed phase change materials, the theoretical analysis shows good predictability for the actual phase transformation process.
