Abstract

A parametric study of the ionic wind produced by a DC corona discharge between two parallel wires in atmospheric air is presented. The experiment intends to examine the effect of the gap distance between the electrodes, the wire diameters, the material and the polarity of the electrodes, the type of gas, the voltage and the current. The current is steady for the positive discharge and pulsed (Trichel pulses) in the negative one. The state of the surface of the electrodes (but not their material) does have an effect on the ionic wind. We verified the analytic prediction that the ionic wind varies as the square root of the current. In our experimental ranges, to maximize the ionic wind, the distance must be the smallest, the electrode diameter dissymmetry the largest. A model is proposed to simulate the ionic wind for our experimental setup. The results with simplified air chemistry are in good agreement with the measurements.
