Abstract

The steady radial distribution of chemical species in a negative corona discharge is predicted with the help of a physico-chemical model that includes both elementary plasma processes and chemical reactions among neutral and charged species. Corona discharge is generated in dry air using a wire-to-cylinder coaxial electrode system. The current-voltage characteristic of the corona current is used as the input data in the numerical model. The computed ozone density is compared with the experimental concentration determined by ultraviolet spectroscopy.
