An explicit CFD model for the DBD plasma actuators using wall-jet similarity approach

Abstract

A simple model for simulating the surface plasma-induced jets is proposed. The characteristics of the wall jet are estimated based on thrust imposed by the plasma and then related to the similarity solution for the viscous wall jet problem to obtain a plasma wall jet velocity profile. Then the plasma-induced flow field outside the plasma discharge region is simulated by simply imposing a plasma wall jet velocity profile in a single streamwise location. The validity of the model for simulating the effect produced by the dielectric barrier discharge (DBD) plasma actuators is tested against some experimental and numerical simulation results.
