The paper presents a simulation model of the negative corona discharge in N_2 under various pressures.The simulated discharge is of a negative point-to-plane mass type,with an inter-electrode separation distance of 20 mm and a symmetry about the axis of discharge.This simulation investigates the behavior of the neutral density and temperature for different pressures in the range of 0.1-10.0 bar.The spatial and temporal evolution of the neutral gas is analyzed based upon the equations of continuity,momentum and energy in a two-dimensional cylindrical geometry model.For that geometry of the system,the FCT(Flux Corrected Transport) technique was adopted.The results show that the pressure plays a significant role of the neutrals dynamics.
