20100110602ELECTRIC FIELD CONTROL METHODS AND APPARATUSES FOR CORONA WIND FANS - The present invention is a method of controlling the electric field in a corona wind fan to eliminate sparks and thereby increase the operating window and mechanical output of the device. A corona wind device moves a gas using ions that are generated by two electrodes. The electric field in a corona wind system is highly non-uniform. An intense field, of limited size, is needed to generate ions. It is desirable for the remainder of the system to be at as low a field as possible so as to prevent sparks from forming between electrodes. A contoured collector electrode creates this desirable electric field over most of a corona wind device. However, the electric field at the edges and ends of a contoured collector remain as weak points in the device. If not addressed, sparks will form prematurely at these points limiting the overall performance. Several methods to control the field at these points were developed.05-06-2010
