摘　　要：针对一低速吸附式静叶栅的抽吸腔体的内部流动,通过改变不同截面的通流面积以期提高吸附式叶栅的气动性能。采用了数值模拟的研究手段,结果表明,腔体的几何改变并不会影响叶栅的主流性能,变截面的腔体几何会导致吸附式叶栅抽吸耗功增加。With the inlet flow in adsorb cavity of a low speed guide vane aerodynamic characteristics of the adsorb blade cascade wanted to be increased by changing the flow area at different sections. The numerical simulation was used, the investigation results showed that the aerodynamic performance of the main flow would not be affected on when the geometry structure of the cavity was changed, and the geometry structure of the cavity with variable cross-section would increase the wasted word for adsorbing.
