Influence of departures from complete thermodynamic equilibrium on transport coefficient values: application to an oxygen plasma

The main transport coefficients (thermal and electrical conductivities, viscosity) of an oxygen plasma at atmospheric pressure and at lower pressures are calculated by a classical formalism described by Hirchfelder et al, using a plasma composition obtained from a collisional radiative model which allows us to take into account the influence of the radiation escape. Results show that the viscosity is not affected by departures from complete thermodynamic equilibrium but that electrical and thermal conductivities are appreciably affected, which has an effect on energy balance equations.
