The plasma field induced by the plasma generator is simulated numerically by the simulation of the flow field at low velocity. The effects of plasma generator excitation intensity, plasma generator size and main flow velocity on the surface layer induced by low velocity fluid are studied. The plasma under investigation was generated by a radio frequency generator and the results showed that the plasma generator had a great influence on the surface layer of the low velocity flowing fluid.The results of this study can be applied to the surface of the aircraft head, wing and engine blade And flow separation control to improve the aircraft and engine flow field characteristics.
