The clogging behavior of a symmetric binary mixture of colloidal particles that are driven in opposite directions through constrictions is explored by Brownian dynamics simulations and theory. A dynamical state with a spontaneously broken symmetry occurs where one species is flowing and the other is blocked for a long time, which can be tailored by the size of the constrictions. Moreover, we fi...

abstract bottom rack intake is one of the most popular structures used for diverting water in mountain region. corrosion and rotten problems of bottom racks inspire the introduction of a new system of bottom intake in which a porous media is replaced by the bottom rack. obviously, clogging and reduction of diverted discharge are the most important problems in this new system, too. in this paper...

Vacuum preloading combined with prefabricated vertical drains (PVDs) system has been widely used to improve the soft clay high water content. Clogging is usually formed around PVDs during vacuum preloading, impeding propagation of pressure and slowing down consolidation process. To understand forming mechanism clogging, particle image velocimetry (PIV) technique tracking (PTV) were adopted in m...
