| 摘 要： | 采用数值方法模拟了低雷诺数条件下NASA Rotor 37跨声速压气机转子内部流场.结果表明,附面层径向涡是该压气机转子流动失稳的一个很重要的原因.通过在该压气机转子叶片吸力面上不同的叶高和轴向弦长处进行抽吸,发现都可以很好的抑制附面层径向涡的发展,压气机转子的稳定工作范围明显扩大.此外还比较了不同的抽吸量对压气机的性能的影响.

| Abstract: | The flow instability of NASA Rotor 37 transonic compressor rotor at low Reynolds number was investigated by numerical simulation.The result shows that the boundary layer radial vortex becomes an important factor for causing compressor flow instability.It's found that the compressor stability range is obviously enlarged by suction on the blade suction surface at different blade heights and axial chords.The influence of suction mass on the characteristic of the compressor was also compared. |

| Keywords: | flow instability low Reynolds number boundary layer radial vortex suction |
