The Duh-Haymet-Henderson (DHH) closure [27-29] is similar to the MV closure but has o as a functional of a function that is closely related to 7(r). This closure has been successful for LJ fluids and their mixtures, even in the case of non-additive mixtures [29]. A comparison of the gij r) for a non-additive mixture, obtained with the DHH closure, is made with simulations in Fig. 5. 

Since the results for thermodynamics from the Yukawa potential, with A = 1.8, are similar to the results of the LJ potential, it is quite possible that the DHH closure may be applicable to the Yukawa potential. With A = 1.5, the thermodynamics of the square well fluid are also similar. Here, too, the DHH closure may be useful. However, the DHH closure has not been applied to either of these potentials. 

Recently, the HAB approach plus the MV closure has been applied both to hard spheres near a single hard wall [24,25] and in a slit formed by two hard walls. Some results [99] for the latter system are compared with simulation results in Fig. 7. The results obtained from the HAB equation with the HNC and PY closures are not very satisfactory. However, if the MV closure is used, the results are quite good. There have been a few apphcations of the HAB equation to inhomogeneous fluids with attractive interactions. The results have not been very good. The fault hes with the closure used and not Eq. (78). A better closure is needed. Perhaps the DHH closure [27,28] would yield good results, but it has never been tried. 

Note that, except for the DHH closure, all of the closures discussed above lead to a bridge function that is always negative or zero. In the case of the DHH closure, there can be a small positive region. It is interesting to note that recent unpublished work indicates that the bridge function may be positive near the critical point. 

Integral equations provide a satisfactory formalism for the study of homogeneous and inhomogeneous fluids. If the usual OZ equation is used, the best results are obtained from semiempirical closures such as the MV and DHH closures. However, this empirical element can be avoided by using integral equations that involve higher-order distribution functions, but at the cost of some computational complexity.

Hole Correction of the Debye-Huckel Coion Density Profile The DHH Theory... 

The results of the simple DHH theory outlined here are shown compared with DH results and corresponding Monte Carlo results in Figs. 10-12. Clearly, the major error of the DH theory has been accounted for. The OCP model is greatly idealized but the same hole correction method can be applied to more realistic electrolyte models. In a series of articles the DHH theory has been applied to a one-component plasma composed of charged hard spheres [23], to local correlation correction of the screening of macroions by counterions [24], and to the generation of correlated free energy density functionals for electrolyte solutions [25,26]. The extensive results obtained bear out the hopeful view of the DHH approximation provided by the OCP results shown here. It is noteworthy that in... 

FIG. 10 The calculated internal energy of a one-component plasma as a function of coupling strength is compared with corresponding simulation results (open circles) by Brush, Sahlin, and Teller (J. Chem. Phys. 45 2102 (1966). The Debye-Huckel (DH) and hole-corrected Debye-Huckel (DHH) theories were used with results as shown (indicated lines).
