利用原位资源的月球蓄热系统动态性能评估

Dynamic performance assessment of a lunar heat storage system utilizing in situ resources

本文建立了结合集热器的蓄热系统动态数学模型,分析了影响蓄热效果的设计参数,通过多目标优化得出了最佳设计参数。结果表明:长度对集热器系统的影响最大。1 m宽的集热器可以收集整个月昼的热量,但2 m宽的集热器只能运行6.4天,可以通过改变集热器宽度来调节蓄热时间。原位资源利用率和蓄热完成率分别达到75.7%和94.2%。

This paper established a dynamic mathematical model of the heat storage system combined with collector,analyzed the design parameters that affect the heat storage effect,and derives the best design parameters through multi-objective optimization.The results show that the length has the greatest influence on the collector system.1 m wide collector can collect the heat of the whole lunar day,but 2 m wide collector can only operate for 6.4 days.The heat storage time can be adjusted by changing the width of the collector.The in-situ resource utilization and heat storage completion rates can reache 75.7% and 94.2%,respectively.
