Transport properties of partially ionized atomic gases with electronic excitation

Abstract

Chemically nonequilibrium ionized gas mixture §ows of (N, N + , e − ) and (O, O + , e − ) with electronic excitation of neutral component are studied.The one-temperature model of transport properties taking into account electronic states of neutral atoms is developed. The transport coe©-cients of thermal and electrical conductivity, di¨usion and thermal diffusion, shear and bulk viscosity are calculated in the temperature range 500 50,000 K for various mixture compositions. Contribution of the electronic degrees of freedom to the transport properties is found to be important.
