A numerical investigation of dielectric barrier discharge aimed to simulate the electro hydro dynamic interaction is presented. A discharge drift diffusive model according to the Townsend avalanche is described and used to duplicate the plasma kinetics of a DBD actuator. The discharge characteristics dependence upon dielectric material and applied voltage are simulated and the EHD force field according to a simplified approach is presented and discussed.
The coupling of DBD results with a fluid dynamic code is also shown.
Finally, a new non invasive diagnostic technique for EHD interaction based on Schlieren imaging is computationally validated.
