On the Construction of a Gas-Dynamic Model of Electrical Conductivity of an Ionized Gas Based on a Supercomputer Simulation of Electron Kinetics

The derivation of a gas-dynamic model of the radiative conductivity of a weakly ionized gas based on an analysis of the electron kinetics is presented. The gas is formed by the impact ionization of rarefied air by fast primary electrons. The distribution function of slow secondary electrons is studied by the local numerical solution of the kinetic equation. The revealed properties of the distribution function are used to derive equations for the concentration, drift velocity, and specific energy of slow electrons.
