Stability analysis of the homogeneous hydrodynamics of a model for a confined granular gas
(American Physical Society, 2016)
The linear hydrodynamic stability of a model for confined quasi-two-dimensional granular gases is analyzed. The system exhibits homogeneous hydrodynamics, i.e., there are macroscopic evolution equations for homogeneous ...

Dynamical behavior of a one-dimensional Ising model submitted to continuous heating and cooling processes
(American Institute of Physics Publising LLC, 1994)
The evolution of a one-dimensional Ising model with Glauber dynamics and an extrinsic energy barrier, submitted to continuous cooling and heating processes, is studied. The model is shown to exhibit many of the properties ...

Uniform self-diffusion in a granular gas
(American Institute of Physics, 2013)
A granular gas composed of inelastic hard spheres or disks in the homogeneous cooling state is considered. Some of the particles are labeled and their number density exhibits a time-independent linear profile along a given ...

Anomalous self-diffusion in a freely evolving granular gas near the shearing instability
(American Physical Society, 2015)
The self-diffusion coefficient of a granular gas in the homogeneous cooling state is analyzed near the shearing instability. Using mode-coupling theory, it is shown that the coefficient diverges logarithmically as the ...

Fluctuations of a piston on top of a fluidized granular gas
(American Institute of Physics, 2009)
A fluidized granular gas in presence of a gravitational field is considered. It is enclosed in a box with a movable piston on the top. Molecular dynamics simulation results show that, if the box is not too wide, the system ...

Shearing instability of a dilute granular mixture
(American Physical Society, 2013)
The shearing instability of a dilute granular mixture composed of smooth inelastic hard spheres or disks is investigated. By using the Navier-Stokes hydrodynamic equations, it is shown that the scaled transversal velocity ...

Steady Representation of the Homogeneous Cooling State of a Granular Mixture
(AIP Publishing, 2012)
The study of a freely evolving granular mixture using particle simulations presents the inherent limitation that, as a consequence of the inelasticity of collisions, the system is continuously cooling. Therefore, the typical ...

Continuous cooling of a one-dimensional bonded fluid: A Monte Carlo simulation study
(American Institute of Physics Publising LLC, 1991)
A kinetic one-dimensional bonded fluid model is formulated by extending a model for water due to Bell. The behavior of the system under continuous cooling is analyzed by use of a Monte Carlo simulation method. It shows a ...
