An equation of state for lennard-jones pure fluids applicable over a very wide temperature range

Abstract Miyano, Y., 1993. An equation of state for Lennard-Jones pure fluids applicable over a very wide temperature range. Fluid Phase Equilibria, 85: 71-80. Monte Carlo simulations of the compressibility factor and internal energy of a Lennard-Jones fluid are reported for 112 state conditions over the density range 0.2 ⩽ π★ ⩽ 1.1 and the temperature range 0.45 ⩽ T★ ⩽ 100 (where θ★ = θσ3 and T★ = k T ϵ) . These simulation results for the compressibility factors and internal energies are combined with those of previous workers to derive an equation of state for the Lennard-Jones fluid that is valid over a very wide range of temperatures. The equation of state used is a modified Benedict-Webb-Rubin equation which is similar to that proposed by Nicolas et al. (Nicolas, J.J., Gubbins, K.E., Streett, W.B. and Tildesley, D.J., 1979. Mol. Phys., 37: 1429-1454).
