This year research on the rheological behavior of concentrated suspensions has focused on the theoretical description of shear thimling and thickening and the developmenb of the accelerated Stokesian Dynamics (ASD) method. 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 RSD has not. The report is intended to give an integrated view of our current efforts.
