Abstract
New calculated thermodynamic properties and transport coefficients of high temperature air are presented. The calculations, which assume local thermodynamic equilibrium, are performed for different pressures (from 0.1 to 1000 atm) in the temperature range from 50 to 30000 K. The results have been obtained by means of the perturbative Chapman-Enskog method, after an appropriate selection of the collision integrals. The calculations include viscosity, total thermal conductivity and electric conductivity. The collision integrals used in calculating the transport coefficients are significantly more accurate than values used in previous theoretical studies. In particular, accurate collision integrals, carried out by Mason (1971), for interactions between charged species were calculated using the attractive and repulsive screened Coulomb potentials.
