Abstract:

Binary diffusion coefficients are reported for the carbon dioxide-argon and carbon dioxide-nitrogen systems at room temperature and at 1150K to 1680K. In addition self-diffusivities of carbon dioxide for the same temperature range are given. Difficulties encountered in reconciling viscosities and diffusivities in terms of a spherically-symmetric molecular model are described. These difficulties may be overcome, so that diffusivities and viscosities may be correlated in terms of the same Lennard-Jones 12-6 potential, provided one treats the carbon dioxide molecule as a spherocylinder and employs the Curtiss-Muckenfuss calculations for rigid, spherocylindrical molecules.
