Thermodynamics of d-dimensional hard sphere fluids confined to micropores.
We derive an analytical expression of the second virial coefficient of d-dimensional hard sphere fluids confined to slit pores by applying Speedy and Reiss' interpretation of cavity space. We confirm that this coefficient is identical to the one obtained from the Mayer cluster expansion up to second order with respect to fugacity. The key step of both approaches is to evaluate either the surfac...
متن کاملLocal size segregation in polydisperse hard sphere fluids
The structure of polydisperse hard sphere fluids, in the presence of a wall, is studied by the Rosenfeld density functional theory. Within this approach, the local excess free energy depends on only four combinations of the full set of density fields. The case of continuous polydispersity thereby becomes tractable. We predict, generically, an oscillatory size segregation close to the wall, and ...
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...
متن کاملBinary hard-sphere fluids near a hard wall
By using the Rosenfeld density functional, we determine the number density profiles of both components of binary hard-sphere fluids close to a planar hard wall as well as the corresponding excess coverage and surface tension. The comparison with published simulation data demonstrates that the Rosenfeld functional, both its original version and sophistications thereof, is superior to previous ap...
متن کاملLocal linear viscoelasticity of confined fluids.
In this paper the authors propose a novel method to study the local linear viscoelasticity of fluids confined between two walls. The method is based on the linear constitutive equation and provides details about the real and imaginary parts of the local complex viscosity. They apply the method to a simple atomic fluid undergoing zero mean oscillatory flow using nonequilibrium molecular dynamics...
