Exact analytic expression for a subset of fourth virial coe cients of polydisperse hard sphere mixtures
نویسنده
چکیده
It is surprisingly di cult to calculate analytic expressions for virial coe cients. Even the exact calculation of the second virial coe cient is in general extremely di cult. If particles have no other interaction than hard core repulsion, things are slightly easier. In the isotropic phase, the second virial coe cient B 2 of two arbitrary, convex particles A and B can be determined by [1]

Exact analytic expression for a subset of fourth virial coefficients of polydisperse hard sphere mixtures
We derive an exact, analytic expression for the fourth virial coefficient of a system of polydisperse spheres under the constraint that the smallest sphere has a radius smaller than a given function of the radii of the three remaining particles.
متن کاملThe six th viria l coe cient of hard disc mix tures RICHARD
New calculations of the sixth virial coe cient are presented for binary hard disc mixtures. For each diameter ratio considered, the calculations involve about 1600 9-dimensional integrals. The integrals are evaluated exactly in d dimensions, and approximately, using the Korobov± Conroy number theoretical method, in the other (9 d ) dimensions, where d is between 4 and 8 for each diagram. The ...
متن کاملScattering functions for multicomponent mixtures of charged hard spheres , including the polydisperse limit . Analytic expressions in the Mean Spherical Approximation
We present a closed analytical formula for the scattering intensity from charged hard sphere fluids with any arbitrary number of components. Our result is an extension to ionic systems of Vrij’s analogous expression for uncharged hard sphere mixtures. Use is made of Baxter’s factor correlation functions within the Mean Spherical Approximation (MSA). The polydisperse case of an infinite number o...
متن کاملThermodynamic 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...
متن کاملRescaled density expansions and demixing in hard-sphere binary mixtures.
The demixing transition of a binary fluid mixture of additive hard spheres is analyzed for different size asymmetries by starting from the exact low-density expansion of the pressure. Already within the second virial approximation the fluid separates into two phases of different composition with a lower consolute critical point. By successively incorporating the third, fourth, and fifth virial ...
