Vibrated granular gas confined by a piston
J. Javier Brey, M. J. Ruiz-Montero
The steady state of a vibrated granular gas confined by a movable piston on the top is discussed. Particular attention is given to the hydrodynamic boundary conditions to be used w…
Velocity fluctuations of a piston confining a vibrated granular gas
J. Javier Brey, M. J. Ruiz-Montero
The steady state velocity fluctuations of a movable piston located on the top of a vibrated granular gas are studied by means of molecular dynamics simulations. From the second mom…
Shear state of freely evolving granular gases
J. Javier Brey, M. J. Ruiz-Montero, A. Dominguez
Hydrodynamic equations are used to identify the final state reached by a freely evolving granular gas above but close to its shear instability. The theory predicts the formation of…
Symmetry breaking and clustering in a vibrated granular gas with several macroscopically connected compartments
J. Javier Brey, R. Garcia-Rojo, F. Moreno +1
The spontaneous symmetry breaking in a vibro-fluidized low-density granular gas in three connected compartments is investigated. When the total number of particles in the system be…
Average energy and fluctuations of a granular gas in the threshold of the clustering instability
J. Javier Brey, M. J. Ruiz-Montero
The behavior of an isolated dilute granular gas near the threshold of its clustering instability is investigated by means of fluctuating hydrodynamics and the direct simulation Mon…
Hydrodynamic profiles for an impurity in a open vibrated granular gas
J. Javier Brey, M. J. Ruiz-Montero, F. Moreno
The hydrodynamic state of an impurity immersed in a low density granular gas is analyzed. Explicit expressions for the temperature and density fields of the impurity in terms of th…
