The Incorporation of Heating Effects in Atmospheric Pressure Gas Discharge

Abstract

The latest extension of the FE-FCT algorithm used for the solution of gas discharge problems is presented in this paper. The solution of Navier Stoke's equations is coupled to the continuity and Poisson's equations to account for the heating effects of the neutral gas species in near atmospheric pressure gas discharges. Adaptive meshing techniques that adjust the mesh in time are also incorporated, so that the highly transient phenomena involved can he captured. Results are presented for the development of avalanches and streamers in a 1 mm uniform field gap in air at atmospheric pressure, in order to validate the new algorithm. The assumption adopted by many authors to date, namely, that there is no significant heating involved early in the development of such a discharge is investigated.
