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…
Persistent holes in a fluid
Florian S. Merkt, Robert D. Deegan, Daniel I. Goldman +2
We observe stable holes in a vertically oscillated 0.5 cm deep aqueous suspension of cornstarch for accelerations a above 10g. Holes appear only if a finite perturbation is applied…
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…
