Abstract

The purpose of this paper is to begin to investigate the use of the commercial particle in cell (PIC) code MAGIC for simulations of Dielectric Barrier Discharges (DBD). The simulations are done in pure N2 at atmospheric pressure and last only a few nanoseconds. The only particle creation - destruction effect we consider is the ionization of N2 by electron impact. The important effect of charge exchange of an ion with its parent gas is not included. Therefore the drag collision frequency applied to the ions is smaller than it should be, which exaggerates the kinetic energy of the ions in these simulations. The electron drag cross section is based on a Bethe cross section with a low energy correction. This tends to exaggerate the electron drag. The discharge is so fast that the neutral atoms have no time to move and are considered to be at rest. We calculate the momentum imparted to the neutral gas during each time step by collisions with the ions and electrons and also the total accumulated momentum density imparted to the neutral gas during the entire discharge, which is very small in these simulations. We find that DBDs with an exposed positive electrode are stronger than those with the electrode embedded in the dielectric.
