On the Prediction of Thermal Conductivity of Gas Mixtures at Low Temperatures
Thermal conductivity of pure gases were correlated by means of an extended form of the modified Enskog theory together with a modified volume-translated Peng-Robinson equation of state at low temperatures and at pressures up to 370 bar. Two different approaches were used in the correlation. A substance and temperature dependent parameter was introduced in both correlations. The pure-component parameters thus obtained were used to predict the thermal conductivity of five binary mixtures (Ar-He, Ar-N2, Ar-Ne, He-N2 and N2-Ne) without using any binary adjustable parameters with various degrees of success.
