Clogging transition of many particle systems flowing through bottlenecks
(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, ...
Experimental proof of faster is slower in systems of frictional particles flowing through constrictions
(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 ...
