Simulation of Hydrosol Deposition in Granular Media
An algorithm is developed for simulating particle deposition from liquid suspensions flowing through granular media, specifically the prediction of the extent of deposition and the change of media permeability on a local basis. The formulation is based on the premise that granular media may be considered as an assembly of collectors represented by a dual-configuration-either spherical or capillaric-to be applied for deposition and permeability reduction considerations. Comparisons with experiments indicate that the simulation algorithm can indeed be used as a predictive tool for estimating the transport and distribution of particulate matter in granular media.
