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…
Ergodic-nonergodic transition in tapped granular systems: The role of persistent contacts
Paula A. Gago, Diego Maza, Luis A. Pugnaloni
Static granular packs have been studied in the last three decades in the frame of a modified equilibrium statistical mechanics that assumes ergodicity as a basic postulate. The can…
Experimental proof of Faster-is-Slower in multi-particle systems flowing through bottlenecks
José M. Pastor, Angel Garcimartín, Paula A. Gago +7
The "faster-is-slower" (FIS) effect was first predicted by computer simulations of the egress of pedestrians through a narrow exit [Helbing D, Farkas I J, Vicsek T, Nature 407:487-…
A topological method to characterize tapped granular media from the position of the particles
Sergio Ardanza-Trevijano, Iker Zuriguel, Roberto Arevalo +1
We use the first Betti number of a complex to characterize the morphological structure of granular samples in mechanical equilibrium. We analyze two-dimensional granular packings a…
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…
