  • Non-equilibrium statistical mechanics formulation of thermal transport properties for binary and ternary gas mixtures
    Avsec, Jurij ; Naterer, Greg F. ; Marčič, Milan
    The paper develops a new statistical formulation to calculate the thermal diffusivity, binary diffusion coefficient, thermal diffusion factor, viscosity and thermal conductivity of gas mixtures with ... non-equilibrium statistical mechanics. For the analytical calculation of transport properties, the models of Kihara and Chapman-Cowling (up to the third order) have been used. Thermal transport properties for mixtures involving carbon monoxide, helium, argon, xenon and krypton have been computed with the new formulation in this paper. New mixing rules for the calculation of transport properties for mixtures are developed. Close agreement is ob- tained between the analytical results (based on statistical mechanics) and experimental data. The results exhibit comparable or better accuracy than previous methods, while providing new insight regarding the detailed staistical mechanisms of intermolecular interactions, as they contribute to the transport property variations with temperature.
