Non-equilibrium thermodynamic and transport properties of carbon-oxygen thermal plasma mixtures including iron vapour effects

Thermodynamic and transport properties of different carbon-oxygen plasmas mixtures are presented for both thermal equilibrium and non-equilibrium conditions. The influence of molecular ions in the computation of non-equilibrium transport properties has been investigated. Results for non-equilibrium properties have been obtained using two different two-temperature methods: the simplified method by Devoto and the recently developed non- simplified method by Rat. Comparisons between the two methods have been reported for carbon-oxygen mixtures. For the LTE case, iron metal vapours have been included in the calculations.
