Colloidal Flow

Abstract

A “two-fluid” system consisting of a concentrated “slurry” of polystyrene microspheres dispersed in water as fluid No. 1 and water as fluid No. 2 is used to study colloidal flow. As the specific weight of polystyrene is about 4% larger than that of water, the “slurry” will flow under the influence of gravitation. The flow is studied in Hele-Shaw cells (closely spaced glass plates). This produces various interfacial instabilities which may be related to viscous fingering (vertical/inclined cells) and “Rayleigh-Bénard”-like convection (horizontal cells).
