Flow actuation using radio frequency in partially ionized collisional plasmas

Abstract

We present a multidimensional theoretical model for a better understanding and the design of the dielectric barrier discharge-induced momentum exchange. Specifically, the formulation is used to predict surface discharge using two-dimensional asymmetric electrode configurations. Model predictions for charge densities, the electric field, and gas velocity distributions are shown to mimic trends reported in the experimental literature. We also predict the electron charge accumulation on the dielectric surface self-limiting the discharge. © 2005 American Institute of Physics.
