چکیده

In this article, the simulation of the physical phenomenon of coaxial corona discharge in air, in DC mode using the finite element method is discussed. Basically, to optimize the production process of ionized gas and any other physical phenomenon, we model and simulate the phenomenon. To simulate this phenomenon, from two cylindrical electrodes, one inside (cathode) and the other outside (anode), the radius of the inner electrode is 100 microns and the distance between the electrodes is 10 cm. A constant voltage of 50 kV is applied to the inner electrode. The outer electrode is considered the ground. Our emphasis is on the formation of charged particles and their behavior in the resulting electric field. In order to avoid the complexity of the problem and save the simulation time, we model in a one-dimensional way and in the results extract the above phenomenon in a two-dimensional way. The gas temperature is 640 K and the air density is considered constant.
