摘要
目的使舱内的流动与换热更好地满足空间站实验舱内的舒适性和仪器舱内的通风冷却性能的要求。方法在数值研究中 ,采用了更为接近实际状况的计算模型 ,模型考虑了通风管道及进出风口对舱内流场的影响 ,这种模型可避免对多个出风口的流量分配作出假设。在微重力条件下 ,研究了空间站载人舱通风系统中进出风口大小对空间站实验舱流场的影响。根据对空间站实验舱内的不同功能区域 ,提出了区域均匀性指标。结果根据研究工况的计算结果可知进风口渐扩和出风口渐缩这种变截面的进出风口的综合性指标最好。
Objective To make the status of flow and heat transfer fit the r equirement of comfortable condition in the experimental cabin and ventilation an d cooling in the apparatus cabin of the space station. Method In pr esent 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 experim ental space station cabin was studied. According to different function zones in the experimental space station cabin, the region at evenness parameter was put forward. Result The taper inlet and crescent outlet had the best in tegrated performance. Conclusion The use of variational section was recommended in designing and building of ventilation project in space station ca bin.
