高负荷扩压叶栅非对称附面层抽吸数值研究
|
摘要
本文研究了某大折转角扩压叶栅单侧端壁开孔抽吸附面层对该叶栅气动性能的影响,数值方法经过了实验校核,抽吸位置位于靠近吸力面的端壁处,沿着叶栅的弦长方向共划分了四个抽吸方案,计算域包括下空腔。研究结果表明:在角区分离点处进行端壁附面层抽吸能够明显地改善抽吸侧角区的流动情况,达到推迟分离和降低损失的效果,但对未抽吸侧角区有不利影响,具体表现为分离提前、角区范围增大。
This paper investigates the influence of asymmetric boundary layer suction through endwall holes on aerodynamic performance in large turning angle compressor cascades. Numerical methods verified by experiment, the suction position located at endwall near suction surface, four suction schemes are divided along the chord length of the cascades, the calculating domain includes cavity. Results show the boundary layer suction on endwall that cover separation point could improve the corner flow condition of the suction side, delay flow separation and reduce losses. But adverse effects arise on corner of the other side without suction, such as earlier flow separation and larger range of corner separation.
