Abstract :
Negative corona discharge in pure oxygen is numerically investigated by means of a physicochemical model that considers both elementary plasma processes (ionization, electron attachment and detachment, ion recombination, etc.) and chemical reactions between neutral species. The chemical kinetics model and the electrical model are coupled through Poisson´s equation. The effect of ozone decomposition on the walls and its influence on the radial distribution of species has been investigated. The results of the numerical simulation are compared with the ozone concentration that has been determined by UV spectroscopy.
