利用数值模拟的方法对跨声速压气机模拟分析。针对叶尖流道中因激波及叶尖泄漏涡等导致的复杂二次流动,利用叶尖周向抽吸槽改善跨声速压气机叶尖流动状态。其结果表明:在近失速工况下叶尖周向抽吸槽有效削弱了叶尖低能损失流动,在合理范围内大流量抽吸会使抽吸效果更好。 Transonic Compressor Simulation Analysis Using Numerical Simulation Method. Aiming at the complicated secondary flow caused by shock wave and tip leakage vortex in the tip flow passage, the tip tip suction groove is used to improve the transonic compressor tip flow state. The results show that in the near-stall condition, the tip sucking slot effectively weakens the low-energy loss of the tip, and suctioning at a large flow rate within a reasonable range will make the suction effect better.
