Using the simplified model of plasma generator

this paper solved electric equation to obtain the electric field and the plasma distribution

and then coupled the electrical force on the ions to flow equation.The results indicate that the electrical field could induce air flowing nearby the electrode interface and generate "wall surface jet flow" effect

increasing the fluid momentum and greatly improving the velocity in the boundary layer.Compared with the flow without plasma

the separation point was deferred about 4% chord

the attachment point was moved up approximately 12% chord

thus the separation scope was reduced obviously.In addition

increasing the voltage and exposing electrode to the surrounding air can enhance the plasma control ability.
