An experimental investigation has been conducted to study the interaction of a gas discharge with the wake generated by a flat plate normal to the free airstream. The free discharge and the free airstream are orthogonal to each other and the electric forces are of the same order as the inertial forces in the absence of the discharge. The facilities include devices for local discharge current measurements, a hot wire anemometer and a visualization system. The analysis of the time histories of the cathodic currents suggests that the flow-discharge configuration considered here may give rise to a coupling between the flow and the electric fields oscillations.

Abstract
An experimental investigation has been conducted to study the interaction of a gas discharge with the wake generated by a flat plate normal to the free airstream. The free discharge and the free airstream are orthogonal to each other and the electric forces are of the same order as the inertial forces in the absence of the discharge. The facilities include devices for local discharge current measurements, a hot wire anemometer and a visualization system. The analysis of the time histories of the cathodic currents suggests that the flow-discharge configuration considered here may give rise to a coupling between the flow and the electric fields oscillations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
