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 ...

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 ...

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 ...

Heat Flux in a Granular Gas
(AIP Publishing, 2012)
A peculiarity of the hydrodynamic Navier-Stokes equations for a granular gas is the modification of the Fourier law, with the presence of an additional contribution to the heat flux that is proportional to the density ...

Memory effects in the relaxation of a confined granular gas
(American Physical Society, 2014)
The accuracy of a model to describe the horizontal dynamics of a confined quasi-two-dimensional system of inelastic hard spheres is discussed by comparing its predictions for the relaxation of the temperature in a homogenous ...

Kinetic equation and nonequilibrium entropy for a quasi-two-dimensional gas
(American Physical Society, 2016)
A kinetic equation for a dilute gas of hard spheres confined between two parallel plates separated a distance smaller than two particle diameters is derived. It is a Boltzmann-like equation, which incorporates the effect ...

Hydrodynamics for a model of a confined quasi-two-dimensional granular gas
(American Physical Society, 2015)
The hydrodynamic equations for a model of a confined quasi-two-dimensional gas of smooth inelastic hard spheres are derived from the Boltzmann equation for the model, using a generalization of the Chapman-Enskog method. ...

Power-law decay of the velocity autocorrelation function of a granular fluid in the homogeneous cooling state
(American Physical Society, 2015)
The hydrodynamic part of the velocity autocorrelation function of a granular fluid in the homogeneous cooling state has been calculated by using mode-coupling theory for a finite system with periodic boundary conditions. ...

Kinetic Theory of a Confined Quasi-Two-Dimensional Gas of Hard Spheres
(MDPI, 2017-02)
The dynamics of a system of hard spheres enclosed between two parallel plates separated a distance smaller than two particle diameters is described at the level of kinetic theory. The interest focuses on the behavior of ...
