摘要
提出了一种可用于航天器热控系统的套管式蓄冰装置,采用热焓法对蓄冷装置的充释冷特性进行了数值模拟,给出了蓄冰装置在充释冷过程中蓄冷介质温度、结融冰厚度和对应充释冷功率随时间的变化,并对不同参数下的计算结果进行了分析比较,可为蓄冷装置的优化设计提供参考。
A ice thermal storage device consisting of annular tubes has been proposed for thermal control system of spacecraft. A theoretical model based on the enthalpy formulation has been developed for predicting the charge and discharge behaviour in this type of ice thermal storage device. Numerical calculations include the temperature distribution, the evolution of the solid-liquid interface, and the determination of how much energy has been stored throughout the energy storage process and the release of energy p...
