摘要
为评估某空间站对接飞船后的整体热性能，建立一个集成全局热数学模型。用NEVADA软件建立了空间站在轨运行状态的辐射模型，获得了空间站的外热流及内部辐射交换系数；用FLUENT软件模拟密封舱内部的空气流动情况，获得了舱内空气的速度分布情况及空气与壁面的换热系数；最后用SINDA／FLUINT建立了该空间站的集成全局热数学模型。集成全局热数学模型综合反映了空间站在轨运行时的整体热行为，可以用来评估空间站不同组成部分及不同热控措施对系统整体热性能的影响，也可以用于分析热控系统的地面试验验证方法及系统的故障模式等。
To evaluate the overall thermal performance of a given space station docking with space ship, the paper builds its integrated overall thermal mathematic model （IOTMM）. The radiant model of the space station operating on orbit is built using NEVADA to achieve the external heat flux and the radiant interchange factors. The air velocity distribution in pressure module and the heat transfer coefficient between air and cabin wall are achieved with FLUENT. Finally, the IOTMM is accom- plished with SINDA/FLUINT. The IOTMM presents the overall thermal behavior when this space station operates on orbit. The effects of different components and thermal control measures on the o- verall thermal performance can be evaluated, and the ground test proving method of thermal control system, the system error mode and so on all can be analyzed with this IOTMM.
