Numerical Simulation of Radial and Axial Evolution of Reduced Electric Field on The Conversion of Nitrogen Oxides
In this paper, we propose to numerically simulate the spatial-temporal (axial and radial) evolution of the density of certain nitrogen oxides present in the gaseous mixture: 74% N2, 10% O2, 8% H2O and 8% CO2 which is subject to a negative corona discharge at room temperature and atmospheric pressure. We study the influence of the reduced electric field E/n (E electric field, n the density) on the chemical kinetics of this mixture. The gas chemistry takes into account 18 species such as: the radicals N, O, H, OH, the ground state molecules N2, O2, H2O, CO2, O3, H2, HNO3, the nitrogen oxides NO, N2O, NO2, NO3, N2O5, metastable species N(2D) and the electrons e- reacting with one another 80 selected chemical reactions. The purpose of this simulation is to complete these studies by analyzing different plasma species under three selected values of reduced electric fields: 100, 200 and 300 Td. The results obtained show an evolution closely related to the reduced electric field.
