Simulation investigation on boundary layer of a plate flow control by plasma aerodynamic actuation

Simulation investigation on boundary layer flow controlled by plasma aerodynamic actuation is performed, in which the influences of the plasma actuation on the boundary layer are regarded as added momentum and thermal energy. The body force of the plasma actuation is obtained by solving a two-dimensional fluid model of the surface discharge; from the body force the momentum and thermal energy acting on the boundary layer are induced, and then introduced into the Navier-Stokes equation as the source term. The influence of the intensity of the plasma aerodynamic actuation, the electrode number and position, as well as the thermal energy is investigated, the results agree with experiments.
