Starting, Travelling & Colliding Vortices: DBD Plasma in Quiescent Air
MetadataShow full item record
Whalley, Richard; Choi, Kwing-So
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.
