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...
متن کاملPhase 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...

متن کاملOptimal packing of polydisperse hard-sphere fluids
We consider the effect of intermolecular interactions on the optimal size-distribution of N hard spheres that occupy a fixed total volume. When we minimize the free-energy of this system, within the Percus–Yevick approximation, we find that no solution exists beyond a quite low threshold (h'0.260). Monte Carlo simulations reveal that beyond this density, the size-distribution becomes bimodal. S...
