Starting, Travelling & Colliding Vortices: DBD Plasma in Quiescent Air

Abstract

Development and interaction of starting vortices initiated by Dielectric Barrier Discharge (DBD) plasma actuators in quiescent air are illustrated in the attached fluid dynamics videos. These include a series of smoke flow visualisations, showing the starting vortices moving parallel or normal to the wall at several different actuator configurations.Comment: 1 page, hyperlinked to two fluid mechanics videos MPEG fomat
