Dynamics of drag and force distributions for projectile impact in a granular medium
Massimo Pica Ciamarra, Antonio H. Lara, Andrew T. Lee +3
Our experiments and molecular dynamics simulations on a projectile penetrating a two-dimensional granular medium reveal that the mean deceleration of the projectile is constant and…
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…
Kink-induced transport and segregation in oscillated granular layers
Sung Joon Moon, Daniel I. Goldman, J. B. Swift +1
We use experiments and molecular dynamics simulations of vertically oscillated granular layers to study horizontal particle segregation induced by a kink (a boundary between domain…
Noise, coherent fluctuations, and the onset of order in an oscillated granular fluid
Daniel I. Goldman, J. B. Swift, Harry L. Swinney
We study fluctuations in a vertically oscillated layer of grains below the critical acceleration for the onset of ordered standing waves. As onset is approached, transient disorder…
