Two dimensional simulations of dielectric barrier discharges using the particle in cell code magic

Summary form only given. We present some results for DBD (Dielectric Barrier Discharge) simulations using the particle in cell (PIC) code MAGIC with improved cross sections to calculate the electromagnetic fields and the ion and electron properties. We consider both cases of the anode exposed or embedded in the dielectric. We only treat discharges in pure N2 at atmospheric pressure. The only particle creation -destruction effect we consider is the ionization of N2 by electron impact. 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. The goal is to produce sufficient force to have a significant effect upon boundary layer flows. At this point the PIC code MAGIC is not yet able to produce useful results.
