Analysis of the thermal conductivity coefficients for gas mixtures: application of the modified enskog theory

The method for the calculation of transport coefficients for mixtures of high-density simple gases, which is a generalization of the modified Enskog theory for pure (individual) gases, is used in a simplified form suggested by the author. The simplification is derived using the perturbation method. Computer codes are compiled for performing an analysis of the coefficients of viscosity and thermal conductivity for multicomponent mixtures of high–density gases. The results of calculation of the thermal conductivity coefficient of a nitrogen–carbon dioxide mixture are compared with relevant experimental data: the deviation does not exceed $7\%$ in the experimentally treated region of states.
