Abstract. Thermodynamic and transport properties of high temperature equilibrium air plasmas have
been calculated in a wide pressure ( ÷ 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. Highlight Paper
