Collective dynamics of macroscopic photoactive matter under alternating excitation patterns
Sára Lévay, Axel Katona, Raúl Cruz Hidalgo +1
We present experiments on the collective dynamics of macroscopic photoactive self-propelled particles subjected to spatiotemporally varying excitation. The particles move within an…
Shape matters: Competing mechanisms of particle shape segregation
D. Hernández-Delfin, D. R. Tunuguntla, T. Weinhart +2
It is well-known that granular mixtures that differ in size or shape segregate when sheared. In the past, two mechanisms have been proposed to describe this effect, and it is uncle…
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…
Modeling particle-fluid interaction in a coupled CFD-DEM framework
Ilberto Fonceca, Diego Maza, Raúl Cruz Hidalgo
In this work, we present an alternative methodology to solve the particle-fluid interaction in the resolved CFDEM coupling framework. This numerical approach consists of coupling a…
The role of initial speed in projectile impacts into light granular media
Kai Huang, Dariel Hernadez Delfin, Felix Rech +2
Projectile impact into a light granular material composed of expanded polypropylene (EPP) particles is investigated systematically with various impact velocities. Experimentally, t…
