corner flow separation 角区流动分离
The results show that a positive bowed blade can restrain the corner separation and change the separation configuration, while it can not avoid the flow separation on the suction surface.
结果表明，正弯可以有效遏止角区分离，改变吸力面的分离形态，但不能完全消除吸力面的分离。
Besides, it can also give understanding of the surface streamlines, vortices in separation region and the corner effect of duct flow.
而且液晶也反映了表面流线，分离区内的涡流和管道流动的角效应。
Endwall transverse movement has greater influence on flow separation structure in corner region than separated suction side boundary layer.
端壁横向流动对角区流动分离结构的影响大于吸力面附面层的分离。
