Reorganization of a 2D disordered granular medium due to a small local cyclic perturbation
E. Kolb, C. Goldenberg, S. Inagaki +1
We measure experimentally the rearrangements due to a small localized cyclic displacement applied to a packing of rigid grains under gravity in a 2D geometry. We analyze the evolut…
Transverse Instability of Avalanches in Granular Flows down Incline
Igor S. Aranson, Florent Malloggi, Eric Clement
Avalanche experiments on an erodible substrate are treated in the framework of ``partial fluidization'' model of dense granular flows. The model identifies a family of propagating…
Erosion waves: transverse instabilities and fingering
F. Malloggi, J. Lanuza, B. Andreotti +1
Two laboratory scale experiments of dry and under-water avalanches of non-cohesive granular materials are investigated. We trigger solitary waves and study the conditions under whi…
Pattern formation by injection of air in a non-Brownian suspension
C. Chevalier, A. Lindner, E. Clement
We study the injection of air in a granular suspension. We use a linear Hele-Saw cell filled with a suspension which is displaced by air, leading to a Saffman-Taylor (fingering) in…
Compaction and mobility in randomly agitated granular assemblies
G. Caballero, J. Lanuza, E. Clement
We study the compaction and mobility properties of a dense granular material under weak random vibration. By putting in direct contact millimetric glass beads with piezoelectric tr…
Dynamic and instability of submarine avalanches
F. Malloggi, J. Lanuza, B. Andreotti +1
We perform a laboratory-scale experiment of submarine avalanches on a rough inclined plane. A sediment layer is prepared and thereafter tilted up to an angle lower than the spontan…
