THERMAL CONDUCTIVITY OF CARBON DIOXIDE AT ONE ATMOSPHERE.
Abstract
A dynamic method has been used to determine the thermal conductivity of carbon dioxide at one atmosphere and 925-1350 K. An empirical Eucken factor, f(T), relating thermal conductivity and viscosity as a function of temperature, T, as well as the analogous quantity, g(T) relating thermal conductivity and self-diffusivity, are determined by smoothing all available data on the range 200-1350 K. The predictions of Mason and Monchick agree well with these smoothed functions at the lower temperatures, but deviations increase to about 10% for f(T) and 20% for g(T) at 1100 K. Predictions are improved somewhat by the use of Schmidt numbers from experiment rather than the values from monatomic theory. The best predictions for high temperatures are obtained by using Mason and Monchick's Eucken factor together with the theory of Curtiss and Muckenfuss for rigid, spherocylindrical molecules. (Author)
