Clustering and phases of compartmentalized granular gases
Physical Review E, 2009This paper experimentally investigates the clustering conditions for compartmentalized monodisperse granular gases, determining the critical particle number and condensation granular temperature at the gas-clustering transition. When one heavier intruding particle is added to a monodisperse gas, it is found that the condensation temperature decreases ...

In this paper, a two-dimensional granular gas of inelastic, rough spheres subject to driving is examined. Either the translational degrees of freedom are agitated proportional to a power \(\left| {v(\vec x)} \right|^\delta\) of the local particle velocity \(v(\vec x)\), or the rotational degrees are agitated randomly with respect to the angular ...

Hydrodynamics of Nearly Smooth Granular Gases
The Journal of Physical Chemistry B, 2005Hydrodynamic equations of motion for a monodisperse collection of nearly smooth homogeneous spheres have been derived from the corresponding Boltzmann equation, using a Chapman-Enskog expansion around the elastic smooth spheres limit. Because in the smooth limit the rotational degrees of freedom are uncoupled from the translational ones, it turns out ...

Length Scales of Clustering in Granular Gases
Physical Review Letters, 1999Clustering of granular gases is caused by the dissipation occurring in particle collisions. We use the generalized dimension, a measure for the inhomogeneity of a spatial distribution of particles to characterize the structural evolution. Furthermore, we quantify the typical length scale of the clusters obtained by 3D simulations using the index of ...

Cluster growth in driven granular gases
Physical Review E, 2017We investigate numerically and theoretically the internal structures of a driven granular gas in cuboidal cell geometries. Clustering is reported and particles are classified as gaseous or clustered via a local packing fraction criterion based on a Voronoi tessellation.

Anomalous diffusion in polydisperse granular gases
Physical Review EWe investigate both ensemble and time-averaged mean-squared displacements of particles in a polydisperse granular system in a homogeneous cooling state and derive rigorous analytical expressions valid both at short and long time scales. The discrepancies in ensemble and time-averaged mean-squared displacements indicate ergodicity breaking in granular ...

It is shown how the Boltzmann equation corresponding to a model granular gas can be systematically analyzed in order to obtain constitutive relations as well as boundary conditions. It appears that the formulation leading to the establishment of boundary conditions is the first systematic approach to the problem even in the realm of molecular gases ...
