Perturbation calculation of the distribution functions of mixtures of hard spheres
Abstract
The distribution functions for a mixture of additive hard spheres of diameter σii are calculated by means of an expansion in powers of σijn – dn, using an unperturbed single-component hard-sphere fluid of diameter d. Although the expansion converges only when the hard spheres in the mixture are nearly equal in size, it is useful because it is the only practical scheme available for obtaining the distribution functions of multicomponent hard- sphere mixtures. © 1972 Taylor & Francis Group, LLC.
