Discharge of elongated grains in silos under rotational shear
Tivadar Pongó, Tamás Börzsönyi, Raúl Cruz Hidalgo
The discharge of elongated particles from a silo with rotating bottom is investigated numerically. The introduction of a slight transverse shear reduces the flow rate by up to…
Discharge of elongated grains from silo with rotating bottom
Kiwing To, Yi-Kai Mo, Tivadar Pongó +1
We study the flow of elongated grains (wooden pegs of length =20 mm with circular cross section of diameter =6 and 8 mm) from a silo with a rotating bottom and a circular o…
Flow in an hourglass: particle friction and stiffness matter
Tivadar Pongó, Viktória Stiga, János Török +5
Granular flow out of a silo is studied experimentally and numerically. The time evolution of the discharge rate as well as the normal force (apparent weight) at the bottom of the c…
Silo discharge of mixtures of soft and rigid grains
Jing Wang, Bo Fan, Tivadar Pongó +6
We study the outflow dynamics and clogging phenomena of mixtures of soft, elastic low-friction spherical grains and hard frictional spheres of similar size in a quasi-two-dimension…
Intermittent flow and transient congestions of soft spheres passing narrow orifices
Kirsten Harth, Jing Wang, Tamás Börzsönyi +1
Soft, low-friction particles in silos show peculiar features during their discharge. The outflow velocity and the clogging probability both depend upon the momentary silo fill heig…
Evolution of shear zones in granular materials
Balazs Szabo, Janos Torok, Ellak Somfai +6
The evolution of wide shear zones (or shear bands) was investigated experimentally and numerically for quasistatic dry granular flows in split bottom shear cells. We compare the be…
