Violation of Molecular Chaos in dissipative gases
Thorsten Poeschel, Nikolai V. Brilliantov, Thomas Schwager
Numerical simulations of a dissipative hard sphere gas reveal a dependence of the cooling rate on correlation of the particle velocities due to inelastic collisions. We propose a c…
Diffusion in Granular Gases of Viscoelastic Particles
Nikolai V. Brilliantov, Thorsten Poeschel
In most of the literature on granular gases it is assumed that the restitution coefficient ε, which quantifies the loss of kinetic energy upon a collision is independent on the imp…
Chains of Viscoelastic Spheres
Thorsten Poeschel, Nikolai V. Brilliantov
Given a chain of viscoelastic spheres with fixed masses of the first and last particles. We raise the question: How to chose the masses of the other particles of the chain to assur…
Granular Gases with Impact-velocity Dependent Restitution Coefficient
Nikolai V. Brilliantov, Thorsten Poeschel
We consider collisional models for granular particles and analyze the conditions under which the restitution coefficient might be a constant. We show that these conditions are not…
A model for collisions in granular gases
Nikolai V. Brilliantov, Frank Spahn, Jan-Martin Hertzsch +1
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 impac…
Granular Gases - the early stage
Nikolai V. Brilliantov, Thorsten Poeschel
We investigate the evolution of the velocity distribution function of a granular gas composed of viscoelastic particles in the homogeneous cooling state, i.e. before clustering occ…
