Transition from granular to Brownian suspension : an inclined plane experiment
Alice Billon, Yoël Forterre, Olivier Pouliquen +1
We experimentally revisite the flow down an inclined plane of dense granular suspensions, with particles of sizes in the micron range, for which thermal fluctuations cannot be igno…
Viscous-inertial transition in dense granular suspension
Franco Tapia, Mie Ichihara, Olivier Pouliquen +1
Granular suspensions present a transition from a Newtonian rheology in the Stokes limit to a Bagnoldian rheology when inertia is increased. A custom rheometer which can be run in a…
Brownian granular flows down heaps
Antoine Bérut, Olivier Pouliquen, Yoel Forterre
We study the avalanche dynamics of a pile of micrometer-sized silica grains in water-filled microfluidic drums. Contrary to what is expected for classical granular materials, avala…
The influence of surface roughness on the rheology of immersed and dry frictional spheres
Franco Tapia, Olivier Pouliquen, Elisabeth Guazzelli
Pressure-imposed rheometry is used to examine the influence of surface roughness on the rheology of immersed and dry frictional spheres in the dense regime. The quasi-static value…
Creeping Avalanches of Brownian Granular Suspensions
Antoine Bérut, Olivier Pouliquen, Yoel Forterre
We study the avalanche dynamics of a pile of micron-sized silica grains in miniaturized rotating drums filled with water. Contrary to what is expected for classical granular materi…
Measurements of the aeolian sand transport saturation length
B. Andreotti, P. Claudin, O. Pouliquen
The wavelength at which a dune pattern emerges from a flat sand bed is controlled by the sediment transport saturation length, which is the length needed for the sand flux to adapt…
