Surface tension and vapor–liquid phase coexistence of the square-well fluid
Vapor–liquid interfacial tension of square-well ~SW! fluids is calculated using three different methods viz., molecular dynamics ~MD! with collision-based virial evaluation, Monte Carlo with virial computed by volume perturbation, and Binder’s density-distribution method in conjunction with grand-canonical transition-matrix Monte Carlo ~GC-TMMC!. Three values of the SW attractive well range par...
متن کاملSurface tension and vapor-liquid phase coexistence of confined square-well fluid.
Phase equilibria of a square-well fluid in planar slit pores with varying slit width are investigated by applying the grand-canonical transition-matrix Monte Carlo (GC-TMMC) with the histogram-reweighting method. The wall-fluid interaction strength was varied from repulsive to attractive such that it is greater than the fluid-fluid interaction strength. The nature of the phase coexistence envel...
متن کاملLiquid-vapor coexistence in square-well fluids: an RHNC study
We investigate the ability of the reference hypernetted-chain integral equation to describe the phase diagram of square-well fluids with four different ranges of attraction. Comparison of our results with simulation data shows that the theory is able to reproduce with fairly good accuracy a significant part of the coexistence curve, provided an extrapolation procedure is used to circumvent the ...
متن کاملAttractive Boson and the Gas-Liquid Condensation
We calculate a grand partition function of the attractive Bose gas in the infinite space within some approximations. Using the idea of the Yang-Lee zeros, it is proved that the gas-liquid condensation occurs before the conventional condition of the Bose-Einstein condensation is satisfied. Further, it is pointed out that Bosons with a zero momentum play a role of a trigger to this gas-liquid con...
متن کاملAnalytic Equation of State for the Square-well Plus Sutherland Fluid from Perturbation Theory
Analytic expressions were derived for the compressibility factor and residual internal energy of the square-well plus Sutherland fluid. In this derivation, we used the second order Barker-Henderson perturbation theory based on the macroscopic compressibility approximation together with an analytical expression for radial distribution function of the reference hard sphere fluid. These properties...
