Numerical Simulation of Plasma Aerodynamic Actuation

The mathematical model of dielectric barrier discharge (DBD) is established for the optimization of plasma aerodynamic actuation and the understanding of its interplay with boundary layer. The influences of the plasma aerodynamic actuation on the fluid are regarded as body force. The body force of the plasma actuation is obtained by solving the potential equation and the charge equation. The effect on the boundary layer is calculated by coupling the body force into the Navier-Stokes equations. The influence of the input voltage and frequency is investigated. The simulation results agree with the experiment research which shows the model poses much better precision. This method is instructional for the mechanism understanding for plasma flow control and can lay a foundation for the application of plasma flow control technology.
