Dense Suspension Rheology

This year research on the rheological behavior of concentrated suspensions has proceeded along three parallel efforts as described below. The goal is to provide a quantitative microstructurally-based description of suspension rheology for a range of concentrations and particle-level interactions. The problem is addressed by both analytical and computational (simulation) approaches. Not all of the work described here has been supported by IFPRI; for example, the work on an accelerated version of Stokesian Dynamics has not. The report is intended to give an integrated view of our current efforts.
