Non-thermal plasma, generated in atmospheric pressure discharges, has been investigated in our laboratory in order to treat highly diluted (300 ppm to 1000 ppm) volatile pollutant. The collision of electrons created in the discharge with atmospheric air, leads to the formation of reactive species that can totally or partially oxidize the pollutants at near ambient temperature. The purpose of the present paper is to show that this process can be successfully modeled using COMSOL Multiphysics® code. Pressure and velocity fields are obtained with the Navier Stokes incompressible equations. Concentrations of the species are obtained using the convection and diffusion equation. The calculations are in good agreement with experimental observations and results.
