Plasma expansion in vacuum gap: Three-fluid hydrodynamic simulation

The paper reports on a numerical simulation of stable stage of plasma flare expansion from an explosive emission center. The calculations were made on the base of the three-fluid hydrodynamic model corrected to provide a consistent description of both electron and ion transfer in plasma and electron transfer in a vacuum gap between plasma and an anode. Concentration, flow velocity, and temperature of plasma flare components are analyzed.
