Calculation of solvation forces between solid particles immersed in a simple liquid

Abstract

Two simple approximations are used to calculate the solvation force between two plane parallel Lennard-Jones solids immersed in a Lennard-Jones liquid. The approximations consist of constructing the liquid singlet distribution function between the solid surfaces at finite separation from the distribution function adjacent to an isolated surface. The results are compared with the forces calculated by the Grand Canonical Ensemble Monte Carlo method.
