title = "Combined Helmholtz energy, extended corresponding states and local-composition model for fluid mixtures",
abstract = "We present a thermodynamic model of mixtures in which the Helmholtz energy is computed from an extended corresponding states (ECS) method with a correction term. The ECS model is based upon the van der Waals one-fluid theory with pure-component shape factors represented as functions of reduced temperature and density. The correction term is given by a local-composition model with a coordination number taken from lattice gas theory. Densities and speeds of sound of binary mixtures were calculated with deviations within ±0.20%, while deviations in bubble-point pressures were within ±2% on average.",
