摘要: 对空间站吸热器高温熔盐相变蓄热地面模拟系统进行了数值分析,得到了太阳模拟器功率、循环工质气体出口温度、相变材料容器壁温等参数的瞬态变化曲线,计算结果表明单元换热管的蓄／放热性能达到了设计要求.Abstract: Numerical calculations were performed for a high temperature phase change thermal energy storage tube system of space station heat receiver ground test demonstration. The output power of sun simulator, the exit temperature of cycle working fluid and the wall temperature of the phase change material containers were calculated. These results showed that the receiving/releasing heat performance of the thermal energy storage tube meet design requirements.
