Abstract: The evacuation speed of pedestrians through bottlenecks usually leads to the faster-is-slower (FIS) phenomenon, which relies on frictional clogging and clusters’ size. However, less attention is given in literature to the rheology of pedestrian crowds… read more here.

Abstract: We numerically investigate the effects of the particle surface roughness on the rheological properties of dense suspension of non-Brownian rough particles. We use the Ball–Melrose approximation to calculate the hydrodynamic interactions and an elastic-plastic monoasperity… read more here.
