We describe a method for determining the contributions to the structure and thermodynamics of interaction site fluids arising from long-ranged perturbations to the siteâ€“site potential. An extension of cluster perturbation theories developed for atomic fluids (optimized cluster theory,...

We find that first-order thermodynamic perturbation theory (TPT1) which incorporates the reference monomer fluid used in the generalized Floryâ€“AB (GFâ€“AB) theory yields an equation of state for fused hard-sphere (FHS) chain fluids that has accuracy comparable to the GFâ€“AB and...

For a certain class of thermodynamic perturbation theories, a generalization of the Gibbsâ€“Bogoliubov inequality holds through second order of perturbation theory and for a subset of terms the inequality is true to infinite order. Using this approximate variational principle, a...

We continue the study of a fluid of hard spheres which contain an off-center attraction site, with the range of attraction restricted so that dimers, but no higher s-mers can be formed. Two approximations, an integral equation and a version of thermodynamic perturbation theory, were previously...

An extension of the dimer version of Wertheimâ€™s thermodynamic perturbation theory is proposed and used to treat polydisperse mixture of the hard-sphere Yukawa chain fluid with chain length polydispersity. The structure and thermodynamic properties of the reference system, represented by...

We calculate for the first time the equation of state and other thermodynamic properties of the planar square-well dumbbell (SWD) fluid. The SWD molecule consists of two fused hard discs of diameter Ïƒ, separated by a reduced separation L*=L/Ïƒ with attractive annuli of outer radii, KÏƒ...

The free energy of square-well (SW) systems of hard-core diameter Ïƒ with ranges 1â‰¤Î»â‰¤3 is expanded in a perturbation series. This interval covers most ranges of interest, from short-ranged SW fluids (Î»â‰ƒ1.2) used in modeling colloids to long ranges (Î»â‰ƒ3) where...

The stability of an unbounded plane elastic plate in gas moving on one side of the plate and at rest on the other is analyzed. The gases are inviscid and in general different. The plate is under tension and has flexural stiffness. It is shown that the system is always unstable to plane...

The thermodynamic and structural properties of purely repulsive hard-core Yukawa particles in the fluid state are determined through Monte Carlo simulation and modeled using perturbation theory and integral equation theory in the mean spherical approximation (MSA). Systems of particles with...
