Velocity distribution in granular gases of viscoelastic particles
Nikolai V. Brilliantov, Thorsten Poeschel
The velocity distribution in a homogeneously cooling granular gas has been studied in the viscoelastic regime when the restitution coefficient of colliding particles depends on the…
Deviation from Maxwell Distribution in Granular Gases with Constant Restitution Coefficient
Nikolai V. Brilliantov, Thorsten Poeschel
We analyze the velocity distribution function of force-free granular gases in the regime of homogeneous cooling when deviations from the Maxwellian distribution may be accounted on…
Extremal collision sequences of particles on a line: optimal transmission of kinetic energy
Thorsten Poeschel, Nikolai V. Brilliantov
The transmission of kinetic energy through chains of inelastically colliding spheres is investigated for the case of constant coefficient of restitution ε=const and impact-velocity…
Coefficient of restitution of colliding viscoelastic spheres
Rosa Ramirez, Thorsten Poeschel, Nikolai V. Brilliantov +1
We perform a dimension analysis for colliding viscoelastic spheres to show that the coefficient of normal restitution depends on the impact velocity g as ε=1-γ_1g^{1/5}+γ_2g^{2…
