Abstract
The influence of plasma actuation frequency low-speed axial compressor stability is studied by experiment and numerical simulation. The results show that the plasma actuation can reduce the unsteady pulsation of the tip leakage flow, increase the main-steam momentum, weaken the leakage flow and the backflow momentum, restrain the swing of the leakage vortex toward the leading edge, and finally enhance the stability operation of the compressor. The unsteady plasma actuation frequency has significant impact on compressor stability. Compressor stability is enhanced with the increase of plasma actuation frequency. The actuation frequency has threshold, when the frequency is higher than 0.5BPF, stabilizing effect is almost the same with the increase of the frequency.
