Solution of the mean spherical model for dipolar mixtures

Abstract

The mean spherical model is solved analytically for mixtures of dipolar fluids. The components are identified by different but additive molecular radii and different magnitudes of the dipole moment. The direct and indirect correlation functions are found to be functionally dependent on the corresponding hard-sphere functions calculated at certain adjusted densities. Equations for the parameters concerned in calculating such densities are given. The reduction to the equal radii case follows immediately from this analysis.
