Description:

Fluids with nontrivial small-scale inhomogeneities (microstructure) include suspensions, emulsions, foams, polymer melts and solutions, surfactant solutions and liquid crystals. Flows of these complex fluids display features that are not found in simple fluids, including interfacial and bulk instabilities, texture formation and evolution and other novel flow phenomena that all can be traced back to the influence the fluid microstructure has on the stresses that develop within the flow. This workshop will focus on the experimental motivation and the modeling of these fluids and phenomena. Topics to be discussed include modeling from microscopic to macroscopic, closures, and model predictions. Areas of special interest include shear rheometry, especially transient and steady state flows, inhomogeneities, shear banding, vorticity banding, three-dimensional flows and stability.
