Transverse vortices induced by modulated granular shear flows of elongated particles
Sára Lévay, Philippe Claudin, Ellák Somfai +1
We perform discrete element method (DEM) simulations of elongated grains in a shear cell for various particle aspect ratios and contact frictions, with an additional heterogeneous…
Effect of particle shape on the flow of an hourglass
Bo Fan, Tivadar Pongó, Raúl Cruz Hidalgo +1
The flow rate of a granulate out of a cylindrical container is studied as a function of particle shape for flat and elongated ellipsoids experimentally and numerically. We find a n…
Force on a sphere suspended in flowing granulate
Jing Wang, Bo Fan, Tivadar Pongó +3
We investigate the force of flowing granular material on an obstacle. A sphere suspended in a discharging silo experiences both the weight of the overlaying layers and drag of the…
Flow of asymmetric elongated particles
Bo Fan, Ellák Somfai, Ralf Stannarius +1
Shear induced orientational ordering of asymmetric elongated particles is investigated experimentally. Corn grains and pegs with one end sharpened are studied using X-ray Computed…
Elongated particles discharged with a conveyor belt in a two-dimensional silo
Bo Fan, Iker Zuriguel, Joshua A. Dijksman +2
The flow of elliptical particles out of a 2-dimensional silo when extracted with a conveyor belt is analyzed experimentally. The conveyor belt - placed directly below the silo outl…
Particle flow rate in silos under rotational shear
D. Hernández-Delfin, T. Pongó, K. To +2
Very recently, To et al.~have experimentally explored granular flow in a cylindrical silo, with a bottom wall that rotates horizontally with respect to the lateral wall \cite{Kiwin…
