Dielectric Barrier Discharges (DBDs) are self-sustaining electrical discharges in electrode configurations containing an insulating material in the discharge path. Dielectric barrier discharge is considered a new method to produce plasma, which is of interest to researchers in various fields. In this article, electrical breakdown and plasma formation with argon atmospheric pressure gas are simulated. To avoid the complexity of the problem and faster convergence, the simulation has been done in one dimension. It has been shown that the optimization of a plasma reactor depends on the distance between the electrodes and the gas flow rate. By changing different discharge gaps, the gap has been optimized and as a result, optimized power consumption has been achieved.
