Unlike Lennard-Jones Parameters for Vapor-Liquid Equilibria
The influence of the unlike Lennard-Jones (LJ) parameters on vapor-liquid equilibria of mixtures is investigated and the performance of eleven combining rules is assessed. In the first part of the work, the influence of the unlike LJ size and energy parameter on vapor pressure, bubble density and dew point composition is systematically studied for the mixtures CO+C2H6 and N2+C3H6, respectively....
متن کاملVapour-liquid equilibria for quadrupolar Lennard- Jones fluids
Monte Carlo calculations in the Gibbs ensemble are reported for pure quadrupolar Lennard-Jones fluids. The vapour-liquid equilibrium curves, critical temperatures, and critical densities are calculated for various quadrupolar strengths (e*’ = Q’/Eu’ = 1.0, 1.5, 2.0 and 2.5). It is shown that as the quadrupolar strength increases both the critical temperature and the critical density increase. C...
متن کاملVapor-liquid equilibria of the two-dimensional Lennard-Jones fluid(s)
Two-dimensional systems are interesting both from a purely theoretical and from an experimental point of view. Examples of real systems that behave effectively as two-dimensional systems are monolayers adsorbed on solid substrates’ and surfactants adsorbed on an air/water interface.’ If a fluid is confined between two parallel plates, the phase behavior of such a system has two limiting cases. ...
متن کاملPhase diagrams of Lennard-Jones fluids
Smit and Frenkel’ have shown that the phase diagram of the two-dimensional Lennard-Jones fluid depends largely on the details of the truncation of the potential. In this Note, Gibbs-ensemble calculations are reported for the three-dimensional Lennard-Jones fluid. As expected, the phase diagram for this system also depends significantly on the details of the truncation. The Lennard-Jones potenti...
متن کاملVapour-liquid coexistence of an active Lennard-Jones fluid.
We study a three-dimensional system of self-propelled Lennard-Jones particles using Brownian dynamics simulations. Using recent theoretical results for active matter, we calculate the pressure and report equations of state for the system. Additionally, we chart the vapour-liquid coexistence and show that the coexistence densities can be well described using simple power laws. Lastly, we demonst...
