The transport of multiphase suspensions in confined geometries is relevant in a diverse range of flows in science and engineering, from drug transport in the bloodstream, to cell separation in microfluidic devices, and proppant transport in fractured gas and geothermal reservoirs. In this talk, a computational framework for the resolved simulation of such suspensions is presented, using the fully coupled lattice Boltzmann and discrete element methods (LBM-DEM) as its basis. Application to industrially relevant problems highlight new and interesting phenomena, including reverse migration of select species in polydisperse suspensions, the profound influence of electrostatics on clogging and jamming in narrow channels, and the potential for flow reversal to break down some of these behaviours.
