Molecular simulation of the high-pressure phase equilibria of binary atomic fluid mixtures using the exponential-6 intermolecular potential

Molecular simulation results using the exponential-6 intermolecular potenti al are reported for the phase behaviour of the atomic binary mixtures of ne on + xenon, helium + neon, helium + argon and helium + xenon. These binary mixtures exhibit both vapour-liquid and liquid-liquid phase equilibria up t o very high pressures. Comparison with experiment indicates good overall ag reement. The results indicate that the exponential-6 intermolecular potenti al is a useful generic potential for molecular simulation. (C) 2000 Elsevie r Science B,V, All rights reserved.
