Swarming and swirling in self-propelled polar granular rods
Arshad Kudrolli, Geoffroy Lumay, Dmitri Volfson +1
Using experiments with anisotropic vibrated rods and quasi-2D numerical simulations, we show that shape plays an important role in the collective dynamics of self-propelled (SP) pa…
Thermal collapse of a granular gas under gravity
Dmitri Volfson, Baruch Meerson, Lev S. Tsimring
Free cooling of a gas of inelastically colliding hard spheres represents a central paradigm of kinetic theory of granular gases. At zero gravity the temperature of a freely cooling…
Dynamics of a bouncing dimer
S. Dorbolo, D. Volfson, L. Tsimring +1
We investigate the dynamics of a dimer bouncing on a vertically oscillated plate. The dimer, composed of two spheres rigidly connected by a light rod, exhibits several modes depend…
Anisotropy driven dynamics in vibrated granular rods
D. Volfson, A. Kudrolli, L. S. Tsimring
The dynamics of a set of rods bouncing on a vertically vibrated plate is investigated using experiments, simulations, and theoretical analysis. The experiments and simulations are…
Partially fluidized shear granular flows: Continuum theory and MD simulations
D. Volfson, L. S. Tsimring, I. S. Aranson
The continuum theory of partially fluidized shear granular flows is tested and calibrated using two dimensional soft particle molecular dynamics simulations. The theory is based on…
MD simulations and continuum theory of partially fluidized shear granular flows
Dmitri Volfson, Lev S. Tsimring, Igor S. Aranson
We carry out a detailed comparison of soft particle molecular dynamics simulations with the theory of partially fluidized shear granular flows. We verify by direct simulations a co…
