Mach cone in a shallow granular layer
Patrick Heil, E. C. Rericha, Daniel I. Goldman +1
We study the V-shaped wake (Mach cone) formed by a cylindrical rod moving through a thin, vertically vibrated granular layer. The wake, analogous to a shock (hydraulic jump) in sha…
Crucial role of sidewalls in velocity distributions in quasi-2D granular gases
J. S. van Zon, J. Kreft, Daniel I. Goldman +3
Our experiments and three-dimensional molecular dynamics simulations of particles confined to a vertical monolayer by closely spaced frictional walls (sidewalls) yield velocity dis…
Stages of Relaxation of Patterns and the Role of Stochasticity on the Final Stage
S. Hu, D. I. Goldman, D. J. Kouri +3
The disorder function formalism [Gunaratne et.al., Phys. Rev. E, {\bf 57}, 5146 (1998)]^M is used to show that pattern relaxation in an experiment on a vibrated layer of brass bead…
