The phase behavior of both pure systems and binary mixtures has been widely studied by molecular simulation [1], using techniques such as the Gibbs ensemble [2], Gibbs-Duhem [3] or histogram reweighing [4] algorithms. The common aim of many of these investigations is to accurately predict the phase diagram using effective intermolecular potentials, most notable the Lennard-Jones potential. In c...

We present a systematic study of the vapor–liquid equilibria prolate Kihara fluids embedding both dipole and quadrupole moments Monte Carlo simulations perturbation theory methods. The agreement between approaches is good allows to shed light on some general features molecular models whose distribution charge can be modeled as plus moments. validation equation state does lead byproduct rapid, u...
