Ozone production and chemical kinetic corona discharge of pure gas O2 species

Abstract

The work presented in this paper aims to study the chemical kinetics of some species previously chosen by corona discharge at atmospheric pressure P = 1 atm and at room temperature T = 300°K, carried out in wire–cylinder geometry in a pure gas O2. In this perspective, a computer program is designed, efficient in time and space, is used to solve the system of fluid dynamic classical equations based on the resolution of the Boltzmann equation. It participates also, in the chemical kinetics of the gas including the equations of continuity, momentum and energy. For numerical resolution, the flux-corrected transport method is applied successfully to electric discharge, and the generated species of pure gas O2 kinetics are obtained. The reactivity of the gas takes into account nine species that interact according to 23 reactions selected in a way calculated to favor the most dominant. The chosen reduced field values are 100, 120, 140,160, 180 and 200 Td. The results obtained show an evolution closely related to the reduced electric field, and the production of ozone is accompanied by the appearance and disappearance of other species.
