When Verlet's approximation for the three-body term that is found in the equation is used, this equation stands with respect to the first self-consistent equation as Verlet's PY2 and HNC2 equations stand to the PY and HNC equations, respectively. Variants and extensions of the procedure ...
An equation is given for the radial distribution function (hereafter the rdf) of a dense Lennard-Jones fluid. The equation explicitly expresses the rdf as ... Goldman,Saul. - 《Journal of Physical Chemistry》 被引量: 22发表: 1979年
The previously established general solution of the Ornstein-Zernike (OZ) equation is elaborated upon further. A systematic and consistent summary of the first-order OZ solutions for various types of potentials is made, which enables one to obtain the first-order radial distribution function (RDF) ...
The radial distribution function g(r) provided by the solution of the Percus-Yevick (PY) equation for hard spheres is rederived in terms of the simplest Pad'e approximant of a function defined in the Laplace space that is consistent with the following physical requirements: g(r) is continuo...

A radial distribution function for hard spheres is obtained, which improves at high densities on the Percus-Yevick function. This is achieved by solving the mean spherical integral equation for a Yukawa form, adjusted to satisfy the Carnahan-Starling equation of state. The solution to the ...
In this work, we solve the Ornstein–Zernike equation in a simple, analytical, and consistent manner to obtain the like and unlike radial distribution functions (RDFs) for charged fluids. To improve mean spherical approximation (MSA) solutions, the direct correlation functions both for the density...
We have shown that the PY and the CHNC equations can be considered as two different approximations to an exact integral equation. On the basis of this way of looking at the PY and CHNC equations and from the comparison of the computed results we have drawn some conclusions. 展开 ...
