| 摘 要： | 对应用射流孔的高负荷压气机直叶栅进行了实验研究,着重研究了孔隙射流对削弱尾缘附近流动分离和损失的效果。实验包括八种叶栅方案,采用五孔探针测量出口速度和压力分布。同时给出吸力面墨迹流动显示和端壁静压分布。结果表明,孔隙射流对端壁静压的影响很小,叶栅中部损失明显降低,最佳开孔位置位于25%叶高处,相对损失最大降低5.5%。

| Abstract: | This article experimentally studies the effects of air injection near the blade trailing edge on flow separation and losses in a highly loaded linear compressor cascade. Aerodynamic parameters of eight cascades with different air injection slot configura- tions are measured by using a five-hole probe at the cascade outlets. Ink-trace flow visualization is performed to obtain the flow details around the air injection slots. The static pressure distribution is clarified with pressure taps on the endwalls. The... |
