摘要
建立了对流换热条件下蓄冷平板单体内凝固过程变化规律的数理模型 ,并用一种简便方法求解了凝固过程非稳态移动界面传热问题 ;讨论了该蓄冷平板的传热特性 ,比较实验值与理论值后两者基本吻合 ,可满足工程设计计算需要。该结果为研究蓄冷平板堆积床凝固传热特性奠定了基础。
The model describing solidification properties of ice storage in a rectangular capsule under the convective heat transfer condition is established.The solidification heat transfer problems have been solved by a simple method based on the heat resistance method.The heat transfer properties of the ice storage have been discussed.The calculation results have been compared with the experimental ones,and the agreement is satisfactory.This method can meet the demands of the engineering calculation.The results can provide bases for dynamic performance researches of stacked rectangular capsules for ice storage system.
