Effect of strong excitation of the CO2 asymmetric mode on transport properties Original Research Article

Transport properties of carbon dioxide with strongly excited asymmetric vibrational mode are studied on the basis of kinetic theory treatment. The kinetic model takes into account anharmonism of molecular vibrations and different rates of various energy exchanges. The method of transport coefficients derivation is proposed. The calculation of nonequilibrium specific heats is carried out using a non-Boltzmann distribution of the molecules over vibrational energy levels. The effect of strong vibrational excitation and anharmonicity on thermal conductivity, shear and bulk viscosity coefficients is estimated.
