A Hybrid PIC-MCC/Fluid Model for Streamer Discharges under High Gas Pressures
This paper proposes a hybrid PIC-MCC/fluid model for streamer discharges in a needle-plane electrode system at a SF6 gas pressure of 0.1 MPa. The Particle-in-cell and Monte Carlo (PIC-MCC) scheme is used to follow electron kinetics, and calculate electron drift velocity and the rate coefficients α ( ionisation ) and η ( attachment) in the region of highly non-uniform field. The obtained data are used in fluid model to find the charge density distribution of ions and electrons. The simulation results show the streamer formation and development and prove the effectiveness of the hybrid model.
