Nature of granular drag in microgravity
Tivadar Pongo, Tianhui Liao, Jinchen Zhao +4
The influence of gravity on the drag force acting on a projectile impacting granular media is investigated experimentally via embedded inertial measurement unit (IMU) sensor and nu…
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…
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…
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…
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…
