Self-Diffusion Coefficients of Lennard-Jones Liquids and Gases for Various Models in the Modified Free Volume Theory:Tables

摘要

We present tables for self-diffusion coefficients of the Lennard-Jonesliquids and gases for various model formulas in the modified free volume theoryof diffusion in the case of reduced temperatures $T^{\ast}=6.0$, 4.0, 1.3, 1.0,0.8, 0.7 with reduced density ranging from $\rho^{\ast}=0.025$ to 1. Theiraccuracies are compared with the molecular dynamic simulation results. In thegas and liquid density regimes, the formula $D_{CERC}$ for the self-diffusioncoefficient is accurate within maximum 4% of the molecular dynamics simulationvalues reported in the literature. It is the most reliable among the formulaspresented
