Abstract

Ozone generation by negative corona discharge has been investigated using a coaxial wire-cylinder electrode system, and the effect of the composition of the anode (the cylinder) and its radius has been analyzed. Specifically, three different radii (0.65, 0.85 and 1.1 cm) and two different materials (stainless steel and aluminium) have been used for the anode. Ozone concentration was measured using a UV spectrophotometer, both during the electrical discharge and after its extinction. The experimental measurements are complemented with the numerical simulation of the problem using a drift-diffusion model that includes ozone decomposition on the anode and the effect of Joule heating.
