Abstract

The purpose of this paper is 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 Argon at atmospheric pressure to avoid many of the complications that occur in air. We study DBDs with an embedded anode and also with an exposed anode. The only particle creation - destruction effect we consider is the ionization of Argon by electron impact. The ion drag is based on the charge exchange of an ion with its parent gas. The electron drag cross section is based on BEB (binary encounter Bethe) cross section with a low energy correction. Our simulations last only about one nanosecond due to the large number of electrons produced, which fill our computer memory. 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 simulation.
