Research Description: We study dynamic phenomena within complex fluids using experimental, computational, and theoretical tools. Complex fluids, encompassing suspensions of particulates, emulsions, and polymeric solutions and melts, serve important roles in biotechnology, nanotechnology, materials science, and emerging industrial technologies. Efficient control and processing of these materials requires an understanding of their transport properties, yet complex fluids often demonstrate unexpected and intriguing behavior under flow.

PIRE Project Description: Instabilities in particle distributions within flowing, concentrated suspensions create difficulties in characterizing their bulk flow properties and predicting their dynamics even in the simplest of cases, such as Poiseuille flow in the limit of low Reynolds number. The vast majority of work has concerned the transport of spherical particles suspended in viscous fluids, with very little research having been performed on suspensions of elongated particles. This collaborative research with Professor Elisabeth Guazzelli (IUSTI, Polytech’Marseille) explores key issues with regard to the fluid dynamics and rheology of fiber suspensions by merging the experimental and computational expertise of the participants.
