叶栅中部和端部二次流均增强，总平均的二次流动能增大。对于该叶栅，叶片反弯曲亦不能提高叶栅流场的气动性能，直叶片叶栅总损失最小。
For the turbine stator cascade, the negative curving of blade can not improve the performance of the cascades as well, the total losses of straight cascade are the lowest.
目的是在减少叶端漩涡，降低叶轮的流动损失，提高风力机的输出功率，将更多的风能转化为电能。
The above is the scale of our research. It aims to decrease tip vortexes, reduce the flow loss of the rotor and improve the output power of the wind turbine.
结果表明弯掠叶栅端部损失降低而叶展中部损失增加，但相应的端部扩压因子有所减小。
The result shows that the swept-curved cascade has lower endwall loss and higher midspan loss as compared with the straight cascade.
