摘　　要：为探究在小尺寸高负荷轴流压气机转子中压力面小翼对气体流动的作用规律,采用经过验证的数值方法,探讨了压力面小翼对某一高负荷压气机转子的性能影响。结果表明,压力面小翼将原型压气机转子的稳定工作裕度提升了6.19%,可以显著降低叶尖泄漏流动的强度,减少二次泄漏的发生,但同时降低了叶尖区域的做功能力,降低了叶尖泄漏流动与尾缘分离流动的动量比,尾缘分离流动强度上升,压气机的总损失增加。在需求更低稳定作用流量的应用场景中,压力面小翼是可以采用的被动控制手段。In order to explore the effect of pressure surface winglet on flow in small-sized and high load axial compressor rotors,a proven numerical simulation method was used to discuss the performance of pressure surface winglets on a high load compressor rotor.The result shows that the pressure surface winglets increases the stable working margin of the prototype compressor rotor by 6.19%,which can significantly reduce the strength of the tip leakage flow and the occurrence of secondary leakage.However,the workability of the tip area is reduced,which reduces the momentum ratio of tip leakage flow and trailing edge separation flow,and increases the strength of trailing edge separation flow and the total compressor loss.The pressure surface winglet is a passive control method that can be used in application scenarios requiring lower stable working mass flow.
