Coexistence Properties of Higher n-Alkanes Modelled as Kihara Fluids: Gibbs Ensemble Simulations.
Result description
The coexistence vapourůliquid properties of higher n-alkanes of large anisotropy (pentane, decane, and pentadecane) modelled by rod-like Kihara fluids were determined using Gibbs-ensemble (GE) and extended Gibbs ensemble (EGE) Monte Carlo simulations. Wefound that for dense, low temperature states the EGE becomes more accurate and efficient than GE. Comparison of the simulation results with those of a second-order perturbation theory shows that, surprisingly, the theory performs reasonably well for models of large elongations (pentadecane) but disagrees considerably for the model of pentane.
