Rayleigh-Taylor Instabilities in Thin Films of Tapped Powder
Jacques Duran
We observe powder ''droplets'' forming when tapping repeatidly an horizontal flat plate initially covered with a monolayer of fine powder particles. Starting from a simple model in…
Ripples in Tapped or Blown Powder
Jacques Duran
We observe ripples forming on the surface of a granular powder in a container submitted from below to a series of brief and distinct shocks. After a few taps, the pattern turns out…
Simulations of Pattern Formation in Vibrated Granular Media
S. Luding, E. Clement, J. Rajchenbach +1
We present simulations of peak pattern formation in vibrated two-dimensional (2D) granulates and measure the dispersion relation of the pattern for various frequencies, acceleratio…
Simulations of dense granular flow: Dynamic Arches and Spin Organization
S. Luding, J. Duran, E. Clement +1
We present a numerical model for a two dimensional (2D) granular assembly, falling in a rectangular container when the bottom is removed. We observe the occurrence of cracks splitt…
