摘　　要：为了研究吸力面合成射流对亚音速轴流压气机气动性能的影响,以一台高转速亚音速轴流压气机转子为对象开展数值研究。结果表明:受到合成射流激励后,压气机流量裕度减小了1.3%,但峰值效率提升了0.47%;分析内部流场后发现,叶顶泄漏及分离损失、通道损失是该压气机的主要损失来源,在叶片的吸力面布置合成射流激励能够有效减少叶顶泄漏及吸力面分离损失、通道损失和出口损失,而且合成射流的吸气作用相比吹气作用对于减少压气机损失更为有利;受到激励后,压气机通道内的气流径向速度更大且向叶顶聚集,导致叶顶堵塞反而比原型压气机更加严重,使得稳定裕度略有下降。To investigate the effect of suction surface synthetic jet on the aerodynamic performance of a subsonic axial flow compressor,a numerical simulation was conducted on a high-speed and subsonic axial flow compressor rotor.Results show that after being excited by the synthetic jet,the flow margin of the compressor decreases by 1.3%,but the peak efficiency increases by 0.47%.After analyzing the internal flow field,it is found that tip leakage separation loss and passage loss are the main sources of the compressor loss.The arrangement of synthetic jet excitation on the suction surface of the rotor blade can effectively reduce the tip leakage,separation loss,passage loss and especially the outlet loss.Moreover,the suction effect of the synthetic jet is more beneficial to reduce the compressor loss than the blowing effect.At the same time,it should also be noted that after being excited,the radial velocity of the flow in the compressor channel increases and gathers towards the tip of the blade,resulting in more serious tip blockage than the prototype compressor,and leading to a slight decrease in the stability margin.
