Shear Banding in Complex Fluids: Wall effects and unstable dynamics

Abstract
In “shear banding” fluids shear flow can induce structure that feeds back non-linearly to induce an apparent phase transition, in which the fluid attains two coexisting states of different apparent viscosities. This is thus a fruitful area for studying non-equilibrium phase transitions. In this talk I will discuss some recent results in the area, including the effects of boundaries, and the degree to which newer experiments conform to a simple description of two coexisting stable states.
Series This talk is part of the Theory of Condensed Matter series.
