摘要: Abstract The grand canonical Monte Carlo (GCMC) simulation method has been used to estimate the disjoining pressure and obtain distribution of density adsorbed Lennard-Jones fluid in finite narrow slits between nanosized surfaces graphite. influence radius cross section slit chemical potential on properties considered. Different contributions from fluid-fluid, fluid-solid solid–solid interactions solvation force have analyzed. Significant effects are observed for slits. oscillatory behaviour mean depends width a is similarly this an infinite slit. A decrease leads some reduction absolute values density. Edge exhibited larger local central area than its periphery. toroidal region with high concentration appears out near edge. Predictions asymptotic theory equilibrium liquid phase confirmed.
