✦ Synopsis

The paper reports the results of new measurements of the thermal conductivity of binary mixtures of helium, neon and argon with carbon monoxide at 27.5°C and in the pressure range 0.7-12 MPa. The viscosity of these mixtures had been measured previously. The availability of their interaction viscosity allows us to calculate the contribution of the internal degrees of freedom. The Monchick-Pereira-Mason equation provides a reasonable, but far from perfect, basis for a correlation. Even though the low-density viscosity of the present mixtures was essentially the same as the corresponding mixtures with nitrogen, the thermal conductivity is different, pointing to a significant contribution from the rotational degrees of freedom.

A comparison between a calculation of the density effect based on a modification of the Tborne-Enskog theory due to Mason et al. shows the same reasonable agreement (of order 2%) as that ascertained in earlier measurements on other mixtures.
