Solution of the mean spherical approximation for polydisperse multi-Yukawa hard-sphere fluid mixture using orthogonal polynomial expansions

Solution of the mean spherical approximation for polydisperse multi-Yukawa hard-sphere fluid mixture using orthogonal polynomial expansions.

The Blum-Hoye [J. Stat. Phys. 19 317 (1978)] solution of the mean spherical approximation for a multicomponent multi-Yukawa hard-sphere fluid is extended to a polydisperse multi-Yukawa hard-sphere fluid. Our extension is based on the application of the orthogonal polynomial expansion method of Lado [Phys. Rev. E 54, 4411 (1996)]. Closed form analytical expressions for the structural and thermod...

Phase coexistence in a polydisperse charged hard-sphere fluid: polymer mean spherical approximation.

We have reconsidered the phase behavior of a polydisperse mixture of charged hard spheres (CHSs) introducing the concept of minimal size neutral clusters. We thus take into account ionic association effects observed in charged systems close to the phase boundary where the properties of the system are dominated by the presence of neutral clusters while the amount of free ions or charged clusters...

Thermodynamic properties of an asymmetric ̄ uid mixture with adhesive hard sphere Yukawa interaction in the mean spherical approximation

The analytical solution of the Ornstein± Zernike equation in the mean-spherical approximation for a Yukawa ̄ uid and adhesive hard sphere Yukawa ̄ uid with factorizable coe cients is used to derive a simple form for the thermodynamic properties for both mixtures. The second system contains an additional interaction. However, the general thermodynamic expressions were obtained in similar form for...
