Abstract
The work in this paper presents the results from numerical investigation of Dielectric Barrier Discharge plasma actuators, applied on a backward facing step geometry. 2D and 3D simulations were carried out indicating that optimisation of plasma operating parameters is only reliable when dealing with 3D simulations. It was found that there is a parameter space in which reduction in reattachment length takes maximum values, up to 22% reduction, and beyond this, the reduction in reattachment length decreases.
