Abstract
A method reported previously for obtaining the residual chemical potential (the amount by which the chemical potential exceeds that for the ideal fluid) based on the use of the Shing–Gubbins method in conjunction with an estimation of the value of the chemical potential of a related hard core model is applied to very dense Lennard-Jones fluid systems at two reduced temperatures (T * = 1•2 and 1•0, where T * = kT/e). Convergence to steady values is obtained economically. Results are shown to be in good accord with previously reported determinations at T * = 1•2 up to reduced densities (ρ* = ρσ³) of 0•95. It is shown that the limit of the range of the present method is probably ρ* ≈ 1•0.
