Opto-mechanical system for the controlled growth of granular piles
Leonanro Dominguez-Rubio, Etien Martinez, Ernesto Altshuler
The formation of sandpiles is a subject if interest in the field of granular matter, but most experiments are unable to control the kinetic energy of the grains added to the apex o…
Velocity profile of granular flows down a heap described by dimensional analysis
Etien Martinez, Oscar Sotolongo-Costa, Alfo Jose Batista-Leyva +1
Gravity-driven thick granular flows are relevant to many industrial and geophysical processes. In particular, it is important to know and understand the particle velocity distribut…
Note: "Lock-in accelerometry" to follow sink dynamics in shaken granular matter
G. Sánchez-Colina, L. Alonso-Llanes, E. Martínez-Román +5
Understanding the penetration dynamics of intruders in granular beds is relevant not only for fundamental Physics, but also for geophysical processes and construction on sediments…
Revolving rivers in sandpiles: from continuous to intermittent flows
E. Altshuler, R. Toussaint, E. Martinez +3
In a previous paper [Phys. Rev. Lett. 91, 014501 (2003)], the mechanism of "revolving rivers" for sandpile formation is reported: as a steady stream of dry sand is poured onto a ho…
Uphill solitary waves in granular flows
E. Martinez, C. Perez-Penichet, O. Sotolongo-Costa +4
We have experimentally observed a new phenomenon in the surface flow of a granular material. A heap is constructed by injecting sand between two vertical glass plates separated by…
Sandpile formation by revolving rivers
E. Altshuler, O. Ramos, A. J. Batista-Leyva +2
Experimental observation of a new mechanism of sandpile formation is reported. As a steady stream of dry sand is poured onto a horizontal surface, a pile forms which has a thin riv…
