A practical guide to modeling low-current quasi-stationary gas discharges: Eigenvalue, stationary, and time-dependent solvers

The work is concerned with the modeling of low-current quasi-stationary discharges, including Townsend and corona discharges. aim to develop an integrated approach suitable for computation whole range existence a discharge from its inception non-stationary transition another form, such as normal glow or corona-to-streamer transition. This task includes three steps: (i) ignition self-sustaining discharge, (ii) evolution increasing current, (iii) determination current where becomes unstable form begins. Each these steps considered in some detail number examples, referring mostly discharges high-pressure air.
