Abstract
Thermal conductivities have been calculated for dense fluid methane from the exact smooth hard-sphere expression valid for monoatomics with core sizes derived from fitting self-diffusion and viscosity data. The results are lower than experimental values by about 16% at all densities greater than the critical density. This difference is attributed to the effect of internal energy transport on this property.
