| 摘 要： | 1引言在叶轮机械叶栅内流动控制中,可以通过在叶片吸力面、端壁上安装翼刀或隔片,控制二次流的发展,降低二次流损失,其中将翼刀加装在吸力面上的控制方式即为吸力面翼刀控制技术。吸力面翼刀主要是通过阻断端壁附面层和叶片吸力面附面层近端壁处低能流动沿吸力面的展向迁移来对

| Abstract: | The numerical simulation was carried out to investigate the effect of the blade fence with different height and different spanwise location on the secondary flow in compressor cascade composed of conventional straight blades. The results show that higher fence will block the spanwise flow better; the counter-rotating fence vortex formation has a close relation with the intensity of spanwise flow. The height of optimal fence,which is located one endwall boundary layer thickness away from the endwall, is equal to the inlet blade boundary layer thickness. |
