bowed blade

基本解释

A negative bowed blade increases the flow separation and the flow performance is reduced remarkably.
反弯则使得叶栅内分离趋势增加，气动性能明显降低。
Bowed blade technique is applied to micro axial fans and the numerical investigation is implemented on its aerodynamic performance of the different types of bowed blades.
采用人工加厚叶栅进口附面层厚度的方法，研究了弯叶片压气机叶栅在不同叶栅进口附面层厚度条件下叶栅特性的变化。
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。
