Threshold phenomena in erosion driven by subsurface flow
Alexander E. Lobkovsky, Bill Jensen, Arshad Kudrolli +1
We study channelization and slope destabilization driven by subsurface (groundwater) flow in a laboratory experiment. The pressure of the water entering the sandpile from below as…
Clustering transitions in vibro-fluidized magnetized granular materials
Daniel L. Blair, A. Kudrolli
We study the effects of long range interactions on the phases observed in cohesive granular materials. At high vibration amplitudes, a gas of magnetized particles is observed with…
Vortices in vibrated granular rods
Daniel L. Blair, T. Neicu, A. Kudrolli
We report the experimental observation of novel vortex patterns in vertically vibrated granular rods. Above a critical packing fraction, moving ordered domains of nearly vertical r…
Periodic orbit analysis of an elastodynamic resonator using shape deformation
T. Neicu, A. Kudrolli
We report the first definitive experimental observation of periodic orbits (POs) in the spectral properties of an elastodynamic system. The Fourier transform of the density of flex…
Shocks in sand flowing in a silo
Azadeh Samadani, L. Mahadevan, A. Kudrolli
We study the formation of shocks on the surface of a granular material draining through an orifice at the bottom of a quasi-two dimensional silo. At high flow rates, the surface is…
Segregation transitions in wet granular matter
Azadeh Samadani, A. Kudrolli
We report the effect of interstitial fluid on the extent of segregation by imaging the pile that results after bidisperse color-coded particles are poured into a silo. Segregation…
