The random gas of hard spheres

open access: yes, 2019
The inconsistency between the time-reversible Liouville equation and time-irreversible Boltzmann equation has been pointed out long ago by Loschmidt. To avoid Loschmidt's objection, here we propose a new dynamical system to model the motion of atoms of ...

Equilibrium fluid-solid coexistence of hard spheres [PDF]

open access: yes, 2012
We present a tethered Monte Carlo simulation of the crystallization of hard spheres. Our method boosts the traditional umbrella sampling to the point of making practical the study of constrained Gibb's free energies depending on several crystalline order-

Phenomenological Approach of the Effective Viscosity of Hard Sphere Suspensions in Shear-Thinning Media

open access: yesApplied Rheology, 2006
In this work we investigate the rheological behaviour of macroscopic buoyant hard spheres dispersed in a shear-thinning suspending fluid. We focus on the phenomenological study of the influence of the shear-thinning behaviour of the suspending medium on ...

How Generic are the Robust Theoretical Aspects of Jamming in Hard Sphere Models?

open access: yes, 2017
In very recent work the mean field theory of the jamming transition in infinite dimensional hard spheres models was presented. Surprisingly, this theory predicts quantitatively numerically determined characteristics of jamming in two and three dimensions.

Vibrational Model of Heat Conduction in a Fluid of Hard Spheres

open access: yesApplied Sciences, 2022
Application of a vibrational model of heat transfer to a fluid made of hard spheres is discussed. The model was originally proposed to describe heat conduction in fluids with soft pairwise interactionsHere, it is shown that only minor modifications are ...

Crystallization of hard spheres under gravity

open access: yes, 2000
We present a simple argument to account for crystallization of hard spheres under the action of a gravitational field. The paper attempts to bridge the gap between two communities of scientists, one working on granular materials and the other on ...

Relaxation rate, diffusion approximation and Fick's law for inelastic scattering Boltzmann models [PDF]

open access: yes, 2008
We consider the linear dissipative Boltzmann equation describing inelastic interactions of particles with a fixed background. For the simplified model of Maxwell molecules first, we give a complete spectral analysis, and deduce from it the optimal rate ...

On extrapolation of virial coefficients of hard spheres

open access: yesCondensed Matter Physics, 2012
Several methods of extrapolating the virial coefficients, including those proposed in this work, are discussed. The methods are demonstrated on predicting higher virial coefficients of one-component hard spheres.

MULTI-COMPONENT MIXTURE OF DIPOLAR HARD SPHERES WITH SURFACE ADHESION

open access: yesCondensed Matter Physics, 2003
Solution of the mean spherical approximation for multi-component model of dipolar hard spheres with surface adhesion is obtained using factorization technique pioneered by Wertheim and Baxter.

Beyond Salsburg–Wood: Glass equation of state for polydisperse hard spheres

open access: yesAIP Advances, 2021
We reconstruct glass equations of state for polydisperse hard spheres with the help of computer simulations. To perform the reconstructions, we assume that hard-sphere glass equations of state have the form Zg(φ, φJ) = Zg(φJ/φ), where Zg, φ, and φJ are ...
