A Trap Model for Clogging and Unclogging in Granular Hopper Flows
Alexandre Nicolas, Angel Garcimartín, Iker Zuriguel
Granular flows through narrow outlets may be interrupted by the formation of arches or vaults that clog the exit. These clogs may be destroyed by vibrations. A feature which remain…
Flow and clogging in a silo with an obstacle above the orifice
Celia Lozano, Alvaro Janda, Angel Garcimartin +2
In a recent paper [Zuriguel et al., Phys. Rev. Lett. 107, 278001 (2011)] it has been shown that the presence of an obstacle above the outlet can significatively reduce the clogging…
Breaking arches with vibrations: the role of defects
Celia Lozano, Geoffroy Lumay, Iker Zuriguel +1
We present experimental results about the stability of arches against external vibrations. Two dimensional strings of mutually stabilizing grains are geometrically analyzed and sub…
Fluctuations of grains inside a discharging two-dimensional silo
Angel Garcimartín, Iker Zuriguel, Alvaro Janda +1
We present experimental data corresponding to a two dimensional dense granular flow, namely, the gravity-driven discharge of grains from a small opening in a silo. We study the mic…
The shape of jamming arches in two-dimensional deposits of granular materials
Angel Garcimartin, Iker Zuriguel, Luis A. Pugnaloni +1
We present experimental results on the shape of arches that block the outlet of a two dimensional silo. For a range of outlet sizes, we measure some properties of the arches such a…
Role of vibrations in the jamming and unjamming of grains discharging from a silo
Cristian Mankoc, Angel Garcimartin, Iker Zuriguel +2
We present experimental results of the jamming of non-cohesive particles discharged from a flat bottomed silo subjected to vertical vibration. When the exit orifice is only a few g…
