Bounds on Surface Stress-Driven Shear Flow [PDF]
Journal of Nonlinear Science, 2013 The background method is adapted to derive rigorous limits on surface speeds and bulk energy dissipation for shear stress driven flow in two and three dimensional channels. By-products of the analysis are nonlinear energy stability results for plane Couette flow with a shear stress boundary condition: when the applied stress is gauged by a ...

Polymer stress tensor in turbulent shear flows [PDF]
Physical Review E, 2005 The interaction of polymers with turbulent shear flows is examined. We focus on the structure of the elastic stress tensor, which is proportional to the polymer conformation tensor. We examine this object in turbulent flows of increasing complexity.
