Abstract :
This paper deals with experimental measurements of the ionic wind velocity of 3 types of corona discharges in air at atmospheric pressure: a DC surface discharge established between two wires flush mounted on the wall of a dielectric, a DC volume discharge in a point-to-grid geometry and an AC surface barrier discharge generated by application of a sine HV between two electrodes flush mounted on both side of a dielectric. The measurement of the ionic wind velocity profiles allows to determine the mechanical power induced by each discharge, and then the electromechanical efficiency of each device.
