Extraction of coherent structures in a rotating turbulent flow experiment
Jori E. Ruppert-Felsot, Olivier Praud, Eran Sharon +1
The discrete wavelet packet transform (DWPT) and discrete wavelet transform (DWT) are used to extract and study the dynamics of coherent structures in a turbulent rotating fluid. T…
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…
Pattern formation and shocks in granular gases
Harry L. Swinney, E. C. Rericha
Granular media such as sand and sugar are ubiquitous in nature and industry but are less well understood than fluids or solids. We consider the behavior of rapid granular flows whe…
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…
Resonance tongues and patterns in periodically forced reaction-diffusion systems
Anna L. Lin, Aric Hagberg, Ehud Meron +1
Various resonant and near-resonant patterns form in a light-sensitive Belousov-Zhabotinsky (BZ) reaction in response to a spatially-homogeneous time-periodic perturbation with ligh…
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…
