Image of FIG. 1.
FIG. 1.

Density profiles of hard-sphere fluids in contact with a hard planar surface, for bulk densities of (a) 0.319, (b) 0.5745, and (c) 0.813. In each case, the solid line was obtained using Eq. (4) with the PY closure for the bulk direct correlation function and VM for the bridge function . The dashed line and dash-dot-dot lines are for the and combinations, respectively. The open circles are the Monte Carlo simulation results. The vertical dotted line denotes the point of particle-surface contact.

FIG. 2.

Density profiles of hard-sphere fluids in contact with a Lennard-Jones 9-3 surface. The bulk density is 0.3; the potential model and parameter values are given in the text. As in Fig. 1, the solid, dashed, and dash-dot-dot lines denote the , , and closure combinations, respectively. The open circles are the Monte Carlo simulation results.

FIG. 3.

Potential energy of a hard sphere in contact with a hard planar surface, for bulk densities of (a) 0.319, (b) 0.5745, and (c) 0.813, as predicted by Eq. (5). The Monte Carlo data shown in Fig. 1 were used as input. In each case, the solid line was obtained with the PY closure for the bulk direct correlation function and VM for the bridge function . The dashed line and dash-dot-dot lines are for the and combinations, respectively. The light dotted line shows the exact potential energy.

Image of FIG. 4.
FIG. 4.

Potential energy of a hard sphere in contact with a Lennard-Jones 9-3 surface, as predicted by Eq. (5). The bulk density was 0.3; the potential model and parameter values are given in the text. The Monte Carlo data shown in Fig. 2 were used as input. As in Fig. 3, the solid, dashed, and dash-dot-dot lines denote the , , and closure combinations, respectively. The open circles denote the exact Lennard-Jones 9-3 potential.
