Complex Fluids and Multiphase Flows

Aerosols, Emulsions, Suspensions, and Foams

In the Dutcher Lab, we are interested in fundamental studies of the dynamics of complex interfaces and multiphase flows, with a particular focus on environmental remediation. Complex fluids are fluidic mixtures featuring multiple phases and mesoscopic length scales, and include atmospheric aerosols, liquid-liquid emulsions, polymeric solutions, and colloidal suspensions. These interface-rich systems are all around us in our everyday lives.

Using macro and micro-scale flow measurements and analytic mathematical modeling, we explore such areas as the thermodynamics of electrolyte-containing atmospheric aerosols, fluid dynamics and rheology of polymeric and particle-laden solutions, and microfluidics of multiphase flows.
