Abstract :This paper presents the one-dimensional simulation of the dielectric barrier discharge (DBD) in pure nitrogenat atmospheric pressure using a sinusoidal supply, within a reactor which consists of two parallel plates. For this purpose,significant reactions among the reactive species in the discharge are taken into account in this work by considering morethan 70 reactions for 13 species. The model used in this study to describe the kinetics of the plasma species is thesecond order fluid model which consists in replacing the Boltzmann equation by these first three moments by using thedrift-diffusion approximation for flux. In order to validate the model developed in this research, a comparison of thesimulated discharge currents obtained with available experimental data is carried out, before presenting the evolution ofthe properties of the plasma species. After that, a parametric study is performed showing the effect of some parameterslike applied voltage, frequency and nature of the coating dielectric material on the characteristics of DBD in nitrogen.Simulation results for a double dielectric DBD reactor are also presented at the end of this paper.Keywords : Fluid model, dielectric barrier discharge, nitrogen plasma, atmospheric pressure
