Green-Kubo representation of the viscosity of granular gases
نویسنده
چکیده
The Green-Kubo representation of the shear viscosity of a dilute gas of inelastic hard disks derived from the Boltzmann equation is evaluated by means of the direct simulation Monte Carlo method. The relationship between the oneparticle dynamics of the original expression and the N-particle dynamics needed for the simulation is analyzed. The presence of velocity correlations in the latter is identified and their possible implications are discussed.

Frequency-dependent fluctuation-dissipation relations in granular gases.
The Green-Kubo relation for two models of granular gases is discussed. In the Maxwell model in any dimension, the effective temperature obtained from the Green-Kubo relation is shown to be frequency independent and equal to the average kinetic energy, known as the granular temperature. In the second model analyzed, a mean-field granular gas, the collision rate of a particle is taken to be propo...
متن کاملSelf-diffusion in granular gases: Green-Kubo versus Chapman-Enskog.
We study the diffusion of tracers (self-diffusion) in a homogeneously cooling gas of dissipative particles, using the Green-Kubo relation and the Chapman-Enskog approach. The dissipative particle collisions are described by the coefficient of restitution epsilon which for realistic material properties depends on the impact velocity. First, we consider self-diffusion using a constant coefficient...
متن کاملLinear hydrodynamics for driven granular gases.
We study the dynamics of a granular gas heated by a stochastic thermostat. From a Boltzmann description, we derive the hydrodynamic equations for small perturbations around the stationary state that is reached in the long time limit. Transport coefficients are identified as Green-Kubo formulas obtaining explicit expressions as a function of the inelasticity and the spatial dimension.
متن کاملNavier - Stokes equations for stochastic lattice
We discuss the diiusive limit of a class of stochastic lattice gases on the cubic lattice Z d. If the initial conditions correspond to a local equilibrium with small deviations from a spatially constant proole, we prove the law of large numbers for the rescaled empirical velocity eld. The limiting eld satisses the Navier-Stokes equation and the viscosity is characterized by variational formulas...
متن کاملFluctuation-Dissipation Equation and Incompressible Navier-Stokes Equations
We review some recent results concerning the hydrodynamical limits of lattice gases, in particular, lattice gases on the cubic lattice Z Z d ; d = 3, with the incompressible Navier-Stokes equations as the hydrodynamical limit. We shall state precisely the law of large numbers theorem stating that for initial distributions corresponding to arbitrary macroscopic L 2 initial data the distributions...
