2015 AIChE Annual Meeting Proceedings

Session: Complex Fluids I: Polymers and Macromolecules

This session of contributed presentations will focus on the hydrodynamics of complex fluids. Topics of interest include the effects of non-Newtonian rheology on flow, flow-induced microstructure, viscoelasticity, and general polymeric and surfactant-laden flows.
