Visualization showing points of interaction in a suspension

Large-Scale Simulations of Suspensions

Snapshot showing points of interaction (blue), with instantaneous stress values shown numerically and color-coded. Understanding the mechanisms of dispersion or agglomeration of particulate matter in complex fluids such as suspensions is of technological importance in many industries ranging from pharmaceuticals to coatings. NASA’s Columbia supercomputer was used to perform large-scale simulations of suspension flow to study the role of particle shape and size distribution and inter-particle interactions in controlling the rheological properties of these fluids.
