To make the status of flow and heat transfer fit the requirement of comfortable condition in the experimental cabin and ventilation and cooling in the apparatus cabin of the space station.
In present numerical simulation, a model approximate the practice at condition of the ventilation pipeline and influence of inlet and outlet was used, so that there is no need of supposing the distribution of outlets. In microgravity condition, the influence of the size of inlets and outlets on the flow field in the experimental space station cabin was studied. According to different function zones in the experimental space station cabin, the region at evenness parameter was put forward.
The taper inlet and crescent outlet had the best integrated performance.
The use of variational section was recommended in designing and building of ventilation project in space station cabin.
使流动和传热状态符合空间站实验舱舒适条件及设备舱通风冷却的要求。
在当前数值模拟中,采用了一个接近通风管道实际情况且考虑进出口影响的模型,从而无需假设出口分布。在微重力条件下,研究了进出口尺寸对空间站实验舱内流场的影响。根据空间站实验舱内不同功能区,提出了均匀度参数区域。
锥形进口和月牙形出口具有最佳综合性能。
建议在空间站舱体通风工程设计和建设中采用变截面。
