为研究进口总压畸变条件下涡流发生器对压气机流场的影响，建立单级轴流压气机模型，计算和分析了不同工况下的压气机内部流场。计算结果显示：在进口畸变条件下，压气机流场恶化，性能降低；使用涡流发生器后，可以有效改善静叶叶根附近的流场，控制叶片尾缘分离，降低沿叶高方向的压力波动，从而削弱进口畸变对效率的负面影响，改善出口压力场，提高压气机性能；相比于均匀的进口条件，在进口畸变条件下，涡流发生器改善压气机性能的作用更加显著。

In order to study the influence of the vortex generator on the compressor flow field under the condition of inlet total pressure distortion, a singlestage axial flow compressor model was established to calculate and analyze the flow field in the compressor under different working conditions. The calculation results show that the flow field of the compressor deteriorates and the performance decreases under inlet distortion. By using the vortex generator, the flow field near the stator blade root can be improved effectively, the trailing edge separation of blade can be controlled, the pressure fluctuation along the blade height can be reduced, so that the negative effect of inlet distortion on efficiency can be weakened, the outlet pressure field can be improved, and the compressor performance can be improved. Compared with uniform inlet condition, the effect of vortex generator on the improvement of compressor performance is more significant under inlet distortion condition.
