Dynamics of cooling in Viscoelastic Granular Gases [PDF]
EPJ Web of ConferencesWe carry out computational study of pattern formation during cooling in assemblies of inelastically colliding granular particles, under force free condition. Typically, in such systems, following a homogeneous cooling phase, a crossover occurs to a phase

Towards anH-theorem for granular gases [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2015 The $H$-theorem, originally derived at the level of Boltzmann non-linear kinetic equation for a dilute gas undergoing elastic collisions, strongly constrains the velocity distribution of the gas to evolve irreversibly towards equilibrium. As such, the theorem could not be generalized to account for dissipative systems: the conservative nature of ...

Bifurcation diagram for compartmentalized granular gases [PDF]
Physical Review E, 2001 The bifurcation diagram for a vibro-fluidized granular gas in N connected compartments is constructed and discussed. At vigorous driving, the uniform distribution (in which the gas is equi-partitioned over the compartments) is stable. But when the driving intensity is decreased this uniform distribution becomes unstable and gives way to a clustered ...

Optimal Control of Uniformly Heated Granular Fluids in Linear Response
Entropy, 2022 We present a detailed analytical investigation of the optimal control of uniformly heated granular gases in the linear regime. The intensity of the stochastic driving is therefore assumed to be bounded between two values that are close, which limits the ...

Granular gases of rough spheres: Velocity, rotation and collision statistics from in-situ measurements, optical data and simulations [PDF]
EPJ Web of ConferencesGranular gases are not only of interest in fundamental physics, but they can also serve as a test ensembles for the validity of collision models employed in (loose) granular matter.

Direct Simulation Monte Carlo and Granular Gases
, 2022 Granular systems are ensembles of inelastic particles which dissipate energy during collisions. Granular systems serve as excellent models for a wide variety of materials such as sand, soils, corn, and powder.

Dynamics of rarefied granular gases
Physical Review E, 2002 This paper presents quite general bidimensional gas-dynamic equations--derived from kinetic theory-which include the fourth cumulant kappa(r,t) as a dynamic field. The dynamics describes a low-density system of inelastic hard spheres (disks) with normal restitution coefficient r.

Geophysical Research Letters, 2016 A coherent Doppler profiler was used to measure coincident time series of velocity (u,w), sediment mass concentration (c), and sediment grain size (d), above mobile sand dunes in unidirectional flow (∼1 m/s, ∼1 m water depth).

Hydrodynamics and rheology of a dilute granular plane Couette flow [PDF]
EPJ Web of ConferencesWe simulate the plane Couette flow of a dilute granular gas using the Direct Simulation Monte Carlo method. We calculate relevant hydrodynamic and rheological quantities and highlight the effects of driving shear rate and inelasticity on them.
