Transport properties of dense fluid argon.
We calculate using molecular dynamics simulations the transport properties of realistically modeled fluid argon at pressures up to approximately 50 GPa and temperatures up to 3000 K. In this context, we provide a critique of some newer theoretical predictions for the diffusion coefficients of liquids and a discussion of the Enskog theory relevance under two different adaptations: modified Enskog theory and effective diameter Enskog theory. We also analyze a number of experimental data for the thermal conductivity of monoatomic and small diatomic dense fluids.
