摘要
在低速风洞上通过详细测量叶栅的出口流场 ,研究了叶片吸力面上不同高度处加翼刀对压气机叶栅损失和二次流的影响。实验结果表明 ,合理地选择翼刀安装位置 ,可有效地控制压气机叶栅的二次流 ,降低叶栅的总损失。
The effects of suction surface fences at different blade height on the cascade loss and secondary flow in compressor cascade were investigated through the detailed cascade exit flow field survey in low speed wind tunnel.The experimental results show that if the position of the suction surface fence can be properly selected,the secondary flow in the compressor cascade can be controlled effectively and the total cascade loss can also be reduced.
