Experimental and theoretical research has been conducted to investigate basic characteristics of an ozone fan utilizing the ionic wind induced in the pin-to-plate corona discharge field. When a high voltage was applied between the electrodes, the ionic wind, which included ozone, flowed from the pin elecrode to a hole of the plate electrode. It was deduced that (1) the ozone concentration is almost linear with respect to the corona current, (2) the ozone concentration was high with the large pin diameter but almost irrelevant with the gap between the electrodes, (3) the energy efficiency of the negative corona was about 14 times higher that of the positive corona, but it was only several %, (4) the ozone generation was reduced at high temperature. It was estimated that the several ppm ozone could be generated and flowed utilizing the negative discharge and the ozone generation was almost eliminated by turning off the polarity.
