Narrow-gap point-to-plane corona with high velocity flows

Corona discharge has been used in the detoxification of chemical agents or their simulants, for which the degree of destruction depends on the strength of the electric field or electron energy. To help clarify this process, a mathematical model describing the narrow-gap point-to-plane corona system has been developed. Narrow-gap electrodes are characterized by extremely high electron activity and the presence of positive and negative ions. The three-dimensional spatial distributions in the electron density and the electric field are of primary interest. The results indicate the potential problems of the corona device and may prove useful for obtaining an optimum design.<
