| 摘要: |
| 针对调整出口导流叶片来减小吊架对压气机流场影响的方法,采用非定常数值模拟和实验方法,对分离式和一体化式吊架进行了研究。分离式吊架情况下,对减小扰动的作用不明显;一体化式吊架情况下,通过适当调整出口导流叶片安装角可以有效地降低转子后的压力扰动,改善流场。该优化方法适合于一体化式吊架。 |

| Abstract: |
| Unsteady numerical simulations and experiments were carried out to investigate the method of restaggering OGV to shield influence of pylons on a low-speed compressor, including separated pylon and separated pylon cases. Results show that restaggering OGV is more effective to reduce disturbance in integrated pylon case but with less effective in separated pylon case. The method of restaggering OGV is more suitable for integrated pylon case. |
