Etude de l’influence du monoxyde d’azote dans un mélange gazeux N2/ O2

Abstract

This research work is devoted to the simulation of the chemical kinetics of a gas mixture N2/O2 (80% N2 et 20% O2) initially polluted with 200 ppm NO. The use of non-thermal cold plasma reactors generated by crown discharges is currently one of the most suitable techniques for the synthesis of nitrogen oxides. The mathematical model used is based on the classical equations of hydrodynamics of a fluid assuming that only diffusive transport phenomena are predominant. The results obtained show that the behavior of O2 is a major factor in the phenomenon, and that the destruction of nitrogen oxide NO is accompanied by the appearance and disappearance of other species, such as nitrogen dioxide NO2, ozone O3, N2O, etc...
