摘要
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。
Moving heat method is introduced for the theoretical heat transfer(condensing and melting)analysis of the organic phase change materials in spheres.Tendency of heat flux and phase change interface vs time has also been obtained.Experimental investigation proved that the theoretical result is agree well with the experiment which carried out by the phase change materials.
