Abstract
Results of Monte Carlo simulations in the Gibbs ensemble for the vapour-liquid equilibria of Stockmayer fluids are presented. The vapour-liquid curves, critical temperatures and critical densities are calculated for dipolar strengths of μ*2 = μ2/ϵσ3 = 1·0 and 2·0. Comparison of these results shows that perturbation theory over-estimates the critical point.
