Abstract
Thermal conductivities coefficients for gaseous state of N2, O2 and CO2 at zero density are determined by the inversion technique. The Lennard-Jones 12-6 (LJ 12-6) potential energy function is used as the initial model potential required by the technique. The Wang Chang-Uhlenbeck-de Boer (WCUB) approach of the kinetic theory of gases has been used for calculating the contribution of molecular degree of freedom to the thermal conductivity of N2, O2 and CO2. Also, the initial density dependence of gaseous thermal conductivity according to the Rainwater-Friend theory, which was given by Najafi et al., has been considered for N2, O2 and CO2.
