Phase Bubbles and Spatiotemporal Chaos in Granular Patterns
Sung Joon Moon, M. D. Shattuck, C. Bizon +3
We use inelastic hard sphere molecular dynamics simulations and laboratory experiments to study patterns in vertically oscillated granular layers. The simulations and experiments r…
Oscillating Fracture in Rubber
Robert D. Deegan, Paul J. Petersan, M. Marder +1
We have found an oscillating instability of fast-running cracks in thin rubber sheets. A well-defined transition from straight to oscillating cracks occurs as the amount of biaxial…
Fluctuations in viscous fingering
Mitchell G. Moore, Anne Juel, John M. Burgess +2
Our experiments on viscous (Saffman-Taylor) fingering in Hele-Shaw channels reveal finger width fluctuations that were not observed in previous experiments, which had lower aspect…
Anomalous self-similarity in two-dimensional turbulence
Charles N. Baroud, Brendan B. Plapp, Zhen-Su She +1
Our velocity measurements on a quasi-two-dimensional turbulent flow in a rapidly rotating annulus yield an inverse cascade with E(k)~k^{-2} rather than the expected E(k)~k^{-5/3}.…
Shocks in supersonic sand
E. Rericha, C. Bizon, M. D. Shattuck +1
We measure time-averaged velocity, density, and temperature fields for steady granular flow past a wedge and calculate a speed of granular pressure disturbances (sound speed) equal…
