A numerical method to simulate radio-frequency plasma discharges
A fully conservative and efficient numerical algorithm is developed for fluid simulations of radio-frequency plasma discharges. Results are presented in one and multiple dimensions for a helium discharge. The algorithm produces accurate results even on fairly coarse grids A without the use of numerical dissipation. The proposed electron flux discretization is more accurate and efficient than two of the most commonly used discretizations: lock-order upwinding (M. S. Barnes. T. J. Colter, and M. E. Elta. 1987. J. Appl. Phys. 61, 81) and Scharfetter-Gummel (D. L. Scharfetter and H. K. Gummel. 1969, IEEE Trans. Electron Devices ED-16, 64). (C) 2002 Elsevier Science (USA).
