在这个物理模式的基础上讨论了角涡引起高流动损失的物理机制。
Based on this physical model, the mechanism has been discussed that high losses are caused by the corner vortexes.
与常规叶片相比，二次流损失较小的后部加载叮型所构成的叶栅内的通道涡在结构上较为稳定。
Compared with conventional blade, the passage vortex structure is more stable in cascade with aft-loaded blade which secondary loss is small.
因此，抽气形式的有源涡控是抑制旋流、减少出口总压平均损失、改善S弯进气道出口流场的有效措施。
Hence, the method of vortex control is available for removing swirl, decreasing total pressure loss, and improving flow field in S-shaped intake.
