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。
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。
The primary goal of this paper is to discuss the engineering application of the bowed and twisted blade on sub-last and last stages of steam turbines.
