Preliminary Development of a Computational Model of a Dielectric Barrier Discharge

Abstract

A 1D model of a plasma actuator has been developed. The plasma actuator is modeled as a dielectric barrier discharge (DBD) and is based on the numerical solution of the electron and ion conservation of mass and momentum equations, in the drift-diffusion regime, coupled with the Poisson equation for the self-consistent calculation of the electric field. An analytic representation of the force density on the neutral gas due to the presence of a plasma is derived, which is applicable within the drift-diffusion regime. The code is validated by comparison to previous calculations and then applied to a series of test problems to examine the behavior of the plasma force density.
