[Numerical study of the effects (correction of efects) of size of inlets and outlets of ventilation system in experimental space station cabin].
OBJECTIVE
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.


METHODS
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.


RESULTS
The taper inlet and crescent outlet had the best integrated performance.


CONCLUSIONS
The use of variational section was recommended in designing and building of ventilation project in space station cabin.
