Thermodynamic and Transport Properties in Equilibrium Air Plasmas in a Wide Pressure and Temperature Range

Thermodynamic and transport properties of high temperature equilibrium air plasmas have been calculated in a wide pressure (0.01 ÷ 100 atm) and temperature range (50 ÷ 60 000 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-H¨ukel 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.
