Calcul Des Sections Efficaces Et Coefficient De Transports Dans Un Plasma D’oxygene

Résumé: This work constitutes a detailed study on the physical parameters of oxygen plasma created by an electric discharge, namely the mechanisms of electronic collision, the cross sections, the electronic energy distribution function and the transport coefficients like reduced Townsend coefficients, diffusion coefficient, mobility and rates of chemical reactions, the chemical kinetics involves 11 chemical reactions with threshold energies up to 19.5 eV. We have analyzed and studied the effect of different species constituting the plasma as métastable species that have an influence on the cross sections of electronic collision, and on the electronic energy distribution function (EEDF), depending on the medium electronic energy, this study was made under the conditions of atmospheric pressure, gas temperature 300 k °, reduced electric field 200 Td, this work is based on the basis of giving TRINITI
