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 ...

Kullback–Leibler Divergence of a Freely Cooling Granular Gas
Entropy, 2020 Finding the proper entropy-like Lyapunov functional associated with the inelastic Boltzmann equation for an isolated freely cooling granular gas is a still unsolved challenge.

Stability of the homogeneous steady state for a model of a confined quasi-two-dimensional granular fluid [PDF]
EPJ Web of Conferences, 2021 A linear stability analysis of the hydrodynamic equations of a model for confined quasi-two-dimensional granular gases is carried out. The stability analysis is performed around the homogeneous steady state (HSS) reached eventually by the system after a ...

Kinetic theory of aggregation in granular flow [PDF]
, 2011 This article presents a mathematical formulation of the aggregation kinetics in granular flow. The traditional kinetic theory and its generalized application to granular flow does not allow for particle size to change with time thus cannot be used to ...

AI-aided visual data analysis for granular gases: Complex particles, high density, and other challenges [PDF]
EPJ Web of ConferencesMicrogravity experiments with three-dimensional (3D) granular gases, i.e., ensembles of freemoving macroscopic particles which collide inelastically, produce large amounts of stereo video footage which require processing and analysis.

Wave Propagation in Granular Materials [PDF]
, 2005 Wave propagation is a fundamental property of all physical systems. The wave speed is directly related to the compressibility of the system and determines the rate at which local disturbances are propagated into the bulk of the material.
