Clogging transition of many particle systems flowing through bottlenecks
Zuriguel, Iker; Parisi, Daniel; Cruz Hidalgo, Raul; Lozano, Celia; Janda, Alvaro; Gago, Paula; Peralta, Juan; Ferrer, Luis; Pugnaloni, Luis; Clement, Eric; Maza, Diego; Pagonabarraga, Ignacio; Garcimartín, Angel (Scientific Reports, 2014)When a large set of discrete bodies passes through a bottleneck, the flow may become intermittent due to the development of clogs that obstruct the constriction. Clogging is observed, for instance, in colloidal suspensions, ... -
Contact network topology in tapped granular media
Arévalo, Roberto; Pugnaloni, Luis; Zuriguel, Iker; Maza, Diego (American Physical Society, 2013)We analyze the contact network of simulated two-dimensional granular packings in different states of mechanical equilibrium obtained by tapping. We show that topological descriptors of the contact network allow one to ... -
Ergodic nonergodic transition in tapped granular systems; The role of persistent contacts
Gago, Paula; Maza, Diego; Pugnaloni, Luis (Papers in Physics, 2016)Static granular packs have been studied in the last three decades in the frame of a modi ed equilibrium statistical mechanics that assumes ergodicity as a basic postulate. The canonical example on which this framework is ... -
Experimental proof of faster is slower in systems of frictional particles flowing through constrictions
Pastor, Jose; Garcimartín, Angel; Gago, Paula; Peralta, Juan; Martín Gomez, Cesar; Ferrer, Luis; Maza, Diego; Parisi, Daniel; Pugnaloni, Luis; Zuriguel, Iker (American Physical Society, 2015)The “faster-is-slower” (FIS) effect was first predicted by computer simulations of the egress of pedestrians through a narrow exit [D. Helbing, I. J. Farkas, and T. Vicsek, Nature (London) 407, 487 (2000)]. FIS refers to ... -
Relevance of system size to the steady state properties of tapped granular systems
Gago, Paula; Maza, Diego; Pugnaloni, Luis (American Physical Society, 2015)We investigate the steady-state packing fraction ϕ and force moment tensor Σ of quasi-two-dimensional granular columns subjected to tapping. Systems of different height h and width L are considered. We find that ϕ and Σ, ... -
Tapped granular packings described as complex networks
Arévalo, Roberto; Pugnaloni, Luis; Maza, Diego; Zuriguel, Iker (Taylor and Francis, 2013)We characterize the structure of simulated two-dimensional granular packings using con- cepts from complex networks theory. The packings are generated by a simulated tapping protocol, which allows us to obtain states in ...
