Free cooling of particles with rotational degrees of freedom
Timo Aspelmeier, Martin Huthmann, Annette Zippelius
Free cooling of granular materials is analyzed on the basis of a pseudo-Liouville operator. Exchange of translational and rotational energy requires surface roughness for spherical…
Dynamics of deviations from the Gaussian state in a freely cooling homogeneous system of smooth inelastic particles
M. Huthmann, J. A. G. Orza, R. Brito
The time dependence of deviations from the Gaussian state in a freely cooling homogeneous system of smooth inelastically colliding spheres is investigated by kinetic theory. We det…
Dynamics of inelastically colliding spheres with Coulomb friction: Relaxation of translational and rotational energy
Olaf Herbst, Martin Huthmann, Annette Zippelius
We investigate the free cooling of inelastic rough spheres in the presence of Coulomb friction. Depending on the coefficients of normal restitution and Coulomb friction , we…
Granular cooling of hard needles
Martin Huthmann, Timo Aspelmeier, Annette Zippelius
We have developed a kinetic theory of hard needles undergoing binary collisions with loss of energy due to normal and tangential restitution. In addition, we have simulated many pa…
Homogeneous cooling of rough, dissipative particles: Theory and simulations
S. Luding, M. Huthmann, S. McNamara +1
We investigate freely cooling systems of rough spheres in two and three dimensions. Simulations using an event driven algorithm are compared with results of an approximate kinetic…
Dynamics of inelastically colliding rough spheres: Relaxation of translational and rotational energy
Martin Huthmann, Annette Zippelius
We study the exchange of kinetic energy between translational and rotational degrees of freedom for inelastic collisions of rough spheres. Even if equipartition holds in the initia…
