Lack of collective motion in granular gases of rotators
New Journal of Physics, 2022 The dynamics of gases made of particles interacting dissipatively—known as granular gases —can be fully described by the translational and rotational motion of the individual particles; however, most of the results in the field refer to the limit of ...

Hydrodynamic modes for granular gases [PDF]
Physical Review E, 2003 The eigenfunctions and eigenvalues of the linearized Boltzmann equation for inelastic hard spheres (d=3) or disks (d=2) corresponding to d+2 hydrodynamic modes, are calculated in the long wavelength limit for a granular gas. The transport coefficients are identified and found to agree with those from the Chapman-Enskog solution.

Mpemba-like effect protocol for granular gases of inelastic and rough hard disks
Frontiers in Physics, 2022 We study the conditions under which a Mpemba-like effect emerges in granular gases of inelastic and rough hard disks driven by a class of thermostats characterized by the splitting of the noise intensity into translational and rotational counterparts ...

Model for collisions in granular gases [PDF]
Physical Review E, 1996 We propose a model for collisions between particles of a granular material and calculate the restitution coefficients for the normal and tangential motion as functions of the impact velocity from considerations of dissipative viscoelastic collisions. Existing models of impact with dissipation as well as the classical Hertz impact theory are included in

Relative entropy of freely cooling granular gases. A molecular dynamics study [PDF]
EPJ Web of Conferences, 2021 Whereas the original Boltzmann’s H-theorem applies to elastic collisions, its rigorous generalization to the inelastic case is still lacking. Nonetheless, it has been conjectured in the literature that the relative entropy of the velocity distribution ...

Nuclear Engineering and Technology, 2022 When assessing the radiological consequences of postulated accident scenarios, it is of primary interest to determine the amount of radioactive fission gas accumulated in the fuel rod free volume.

Driven fragmentation of granular gases [PDF]
Physical Review E, 2008 The dynamics of homogeneously heated granular gases which fragment due to particle collisions is analyzed. We introduce a kinetic model which accounts for correlations induced at the grain collisions and analyze both the kinetics and relevant distribution functions these systems develop.

Driven granular gases with gravity [PDF]
Physical Review E, 2001 We study fluidized granular gases in a stationary state determined by the balance between an external driving and the bulk dissipation. The two considered situations are inspired by recent experiments, where the gravity plays a major role as a driving mechanism: in the first case gravity acts only in one direction and the bottom wall is vibrated, in ...
