N2 - The effect of the inclination angle between the high voltage electrode (needle) and the grounded one (plane) on the ionic wind jet direction is considered. Ionic wind is induced by positive corona discharge. Experimental data (instantaneous velocity field observed using PIV-method) show that jet direction is defined primarily by the needle inclination. The computer simulation based on the finite element method allows one to reproduce both the current-voltage characteristics and the flow pattern with a good agreement and also facilitates a physical explanation of the strong influence of the needle inclination on the ionic wind direction.
