Homogeneous cooling state of a low-density granular flow
(American Physical Society, 1996)
The homogeneous cooling state of a granular flow of smooth spherical particles described by the Boltzmann equation is investigated by means of the direct simulation Monte Carlo method. The velocity moments and also the ...
Article
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 ...
Article
Self-diffusion in freely evolving granular gases
(American Institute of Physics, 1994)
A self-diffusionequation for a freely evolving gas of inelastic hard disks or spheres is derived starting from the Boltzmann–Lorentz equation, by means of a Chapman–Enskog expansion in the density gradient of the tagged ...
Article
Steady state of a fluidized granular medium between two walls at the same temperature
(American Physical Society, 1998)
The steady state of a low-density gas of inelastic hard spheres confined between two parallel walls at the same temperature is studied. Because of the dissipation in collisions, the state is not uniform but highly inhomogeneous ...
Article
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 ...
Article
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 ...
