Multi-scale clustering in granular surface flows
D. Bonamy, F. Daviaud, L. Laurent +2
We investigate steady granular surface flows in a rotating drum and demonstrate the existence of rigid clusters of grains embedded in the flowing layer. These clusters are fractal…
Experimental study of granular surface flows via a fast camera: a continuous description
D. Bonamy, F. Daviaud, L. Laurent
Depth averaged conservation equations are written for granular surface flows. Their application to the study of steady surface flows in a rotating drum allows to find experimentall…
"Barchan" dunes in the lab
O. Dauchot, F. Lechenault, C. Gasquet +1
We demonstrate the feasibility of studying dunes in a laboratory experiment. It is shown that an initial sand pile, under a wind flow carrying sand, flattens and gets a shape recal…
Traveling waves in a fluid layer submitted to a horizontal temperature gradient
F. Daviaud, J. M. Vince
We report experimental observations of traveling waves in a pure fluid with a free surface situated in a long container submitted to a horizontal temperature gradient perpendicular…
