Abstract.

Thermodynamic and transport properties of high temperature equilibrium air plasmas have been calculated in a wide pressure ( \(0.01\div100\)  atm) and temperature range ( \(50\div60\,000\)  K). The results have been obtained by using a self-consistent approach for the thermodynamic properties and higher order approximation of the Chapman-Enskog method for the transport coefficients. Debye-Hükel corrections have been considered in the thermodynamic properties while collision integrals of charge-charge interactions have been obtained by using a screened Coulomb potential. Calculated values have been fitted by closed forms ready to be inserted in fluid dynamic codes.
