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…
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…
Unjamming a granular hopper by vibration
A. Janda, D. Maza, A. Garcimartin +3
We present an experimental study of the outflow of a hopper continuously vibrated by a piezoelectric device. Outpouring of grains can be achieved for apertures much below the usual…
The flow rate of granular materials through an orifice
C. Mankoc, A. Janda, R. Arévalo +4
The flow rate of grains through large orifices is known to be dependent on its diameter to a 5/2 power law. This relationship has been checked for big outlet sizes, whereas an empi…
