Implicit Difference Scheme to Calculate Electric Fields

概要

論文の詳細を見る
A difference scheme was proposed to calculate glow discharges with a time step Δt that is not limited by the inequality Δt<ε_0/e|μ_eN|, where e0is the permittivity in free space, e is the unit charge, μ_e is the electron mobility and N is the electron density. Calculations were made with a beam model for helium dc glow discharges. The model predicted high-density cold electrons in the negative glow. Calculations were made with a Δt which was 50 times larger than the one limited by the above inequality for the proposed scheme; the value of Δt could be determined from a physical point of view.
