Granular flow through an aperture: influence of the packing fraction
Maria Alejandra Aguirre, Rosario De Schant, Jean-Christophe Géminard
For the last 50 years, the flow of a granular material through an aperture has been intensely studied in gravity-driven vertical systems (e.g. silos and hoppers). Nevertheless, in…
Pressure independence of granular flow through an aperture
Maria Alejandra Aguirre, Juan G. Grande, Adriana Calvo +2
We experimentally demonstrate that the flow rate of granular material through an aperture is controlled by the exit velocity imposed to the particles and not by the pressure at the…
Friction and dilatancy in immersed granular matter
Thibaut Divoux, Jean-Christophe Géminard
The friction of a sliding plate on a thin immersed granular layer obeys Amonton-Coulomb law. We bring to the fore a large set of experimental results which indicate that, over a fe…
