Abstract

Miyano Y., 1991. Equation of state for Lennard-Jones fluid mixtures. Fluid Phase Equilibria, 66:125-141. Using a mixing rule based on the Barker-Henderson perturbation theory, an equation of state for Lennard-Jones pure fluids is extended to mixtures. This equation of state has been tested against computer simulation results for the Lennard-Jones binary mixtures. The Weeks-Chandler-Andersen (WCA) perturbation theory and three other mixing rules, a van der Waals one-fluid model, a modified van der Waals one-fluid model and a mean density approximation, have also been tested. The comparison with the computer simulation results shows the WCA theory and the equation of state using the proposed mixing rule give excellent results.
