| 摘 要： | 以NASA Rotor 37压气机为研究对象,进行了从堵塞点到失稳点的全三维定常数值模拟研究。通过对不同工况下转子叶尖间隙涡的对比分析,揭示了压气机在该转速下的失稳首先是由泄漏涡破裂造成的叶尖通道堵塞,进而扩展到整个叶排形成整机失速,此时叶片吸力面分离造成的堵塞作用还没有达到使压气机失速的程度。 |
| 关 键 词： | 压气机 数值模拟 间隙涡 失速 |

| Abstract: | Research was conducted on the NASA Rotor 37 with 3D unsteady numerical simulation from chocking to near stall.On the base of tip vortexes under different operation models,stall results from the abruption of gap vortex which blocks passage of blade tip.And then it diffuses to the whole blade row at the same time of compressor stall.On the other hand,the blockage from suction side separation is far from the extent of compressor stall. |
| Keywords: | compressor mumerical simulation tip vortex stall |
