Origin of density clustering in a freely evolving granular gas
(American Physical Society, 1999)
The physical mechanisms leading to the development of density inhomogeneities in a freely evolving low density granular gas are investigated. By means of the direct simulation Monte Carlo method, numerical solutions of the ...

On the breakup of slender liquid bridges: Experiments and a 1-D numerical analysis
(ScienceDirect, 1999-07)
Slender axisymmetric dielectric liquid bridges are made stable by the action of an axial electric field. In this paper, the subsequent dynamics of a slender liquid bridge after turning off the electric field is considered. ...

Simple model with facilitated dynamics for granular compaction
(American Physical Society, 1999)
A simple lattice model is used to study compaction in granular media. As in real experiments, we consider a series of taps separated by large enough waiting times. The relaxation of the density exhibits the characteristic ...

On the validity of linear hydrodynamics for low-density granular flows described by the Boltzmann equation
(European Physical Society, 1999)
The direct Monte Carlo simulation method is used to check the validity of the hydrodynamic description of a low-density granular flow in the linear region about the homogeneous cooling state. Good agreement is found between ...

High energy tail in the velocity distribution of a granular gas
(American Physical Society, 1999)
The Enskog-Boltzmann equation for a homogeneous freely evolving system of smooth hard disks colliding inelastically is solved by means of the direct simulation Monte Carlo method. The distribution function shows an exponential ...
