Fractal Substructures due to Fragmentation and Reagglomeration
Dietrich E. Wolf, Thorsten Poeschel, Thomas Schwager +2
Cohesive powders form agglomerates that can be very porous. Hence they are also very fragile. Consider a process of complete fragmentation on a characteristic length scale ,…
Correlation of spin and velocity in granular gases
W. T. Kranz, N. V. Brilliantov, T. Poeschel +1
In a granular gas of rough particles the spin of a grain is correlated with its linear velocity. We develop an analytical theory to account for these correlations and compare its p…
Breakdown of the Sonine expansion for the velocity distribution of Granular Gases
Nikolai V. Brilliantov, Thorsten Poeschel
The velocity distribution of a granular gas is analyzed in terms of the Sonine polynomials expansion. We derive an analytical expression for the third Sonine coefficient a_3. In co…
Collision of Adhesive Viscoelastic Particles
Nikolai V. Brilliantov, Thorsten Poeschel
The collision of convex bodies is considered for small impact velocity, when plastic deformation and fragmentation may be disregarded. In this regime the contact is governed by for…
Long-time behavior of Granular Gases with impact-velocity dependent coefficient of restitution
Thorsten Poeschel, Nikolai V. Brilliantov, Thomas Schwager
A gas of particles which collide inelastically if their impact velocity exceeds a certain value is investigated. In difference to common granular gases, cluster formation occurs on…
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…
