Abstract

A physicochemical model is formulated to obtain the steady radial distribution of chemical species in a negative corona discharge. The corona is generated using a wire-to-cylinder ozonizer filled with pure oxygen at atmospheric pressure and ambient temperature. The experimental values of the current-voltage characteristic are used as input to the physicochemical model. The spatially averaged ozone density is then computed as a function of the current intensity and compared with the experimental concentrations determined by ultraviolet spectroscopy
