| 摘 要： | 在压气机静叶叶栅端壁适当位置进行边界层抽吸，可以控制平面叶栅内的流动分离，提高平面叶栅的气动负荷。为考察抽吸槽道不同布置方案对平面叶栅气动性能的影响，在哈尔滨工业大学发动机气体动力研究中心的跨声速风洞上，对不同抽吸槽道布置方案的压气机平面叶栅进行了吹风实验与数值模拟。结果表明:端壁边界层抽吸可以有效降低平面叶栅的总压损失，其效果与抽吸槽道布置的数量有关。

| Abstract: | Boundary layer suction can control the flow separation in the compressor cascade and increase the aerodynamic load of the cascade. To investigate the influence of the arrangement of suction slots on the aerodynamic performance of the compressor cascade, blowing experiments were carried out in the transonic wind tunnel of the Engine Aerodynamic Research Center of Harbin Institute of Technology. At the same time, the numerical simulation of the cascade was carried out. The results show that the endwall boundary layer suction can effectively reduce the total pressure loss of cascades. The effect of boundary layer suction is related to the number of suction slots. |
