作者在国际上较早开展了轴流压气机等离子体流动控制研究工作,经过近十年的研究积累,对轴流压气机等离子体流动控制建立了较为深刻的认识。本文首先简要展示了轴流压气机等离子体流动控制的部分研究进展:以压气机叶栅为研究对象,分析了等离子体激励对叶顶泄漏流抑制的规律和机制;通过数值仿真和实验,研究了等离子体激励对高负荷轴流压气机失速的流动控制规律和机制;以高速压气机叶栅为研究对象,探索了吸力面和端壁等离子体激励对高速压气机三维角区分离的流动控制规律;然后介绍了等离子体激励式压气机的概念;最后给出了对未来研究工作的展望。
The authors launched earlier researches on the plasma flow control of the axial compressor,and with the research and accumulation of ten years' time,deep understanding on the plasma flow control of axial compressor has been established.This paper shows some of the progress of the research of the authors on the plasma flow control of axial compressor firstly.The law and mechanism of the suppression of the tip leakage flow with plasma actuation are analyzed,based on the researches on a compressor cascade.The law and mechanism of the suppression of the axial compressor stall with plasma actuation are researched with both numerical and experimental methods.With a high-speed compressor cascade,the flow control law of the suction surface and endwall plasma actuations in suppressing the high-speed compressor three-dimensional corner separation is explored.The notion of the plasma actuated compressor is introduced too,and at the end of the paper the outlook of the future work is provided.
