Thermal conductivity of hydrogen-nitrogen and hydrogen-carbon-dioxide gas mixtures
The thermal conductivity of H2-N2 and H2-CO2 mixtures has been measured from -15 to 200°C by using the thick-wire variant of the hot-wire method. The experimental values have been compared with those calculated from the Hirschfelder-Eucken formula. Although fairly satisfactory agreement between theory and experiment is obtained it appears that for a precise interpretation of the thermal conductivity of polyatomic gas mixtures a better representation of the cross-relaxation phenomena is necessary.
