Plasma Flow Control of Axial Compressor

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.
