Effects of Non-local Stress on the Determination of Shear Banding Flow

C. -Y. David Lu, Peter D. Olmsted, R. C. Ball

We analyze the steady planar shear flow of the modified Johnson-Segalman model, which has an added non-local term. We find that the new term allows for unambiguous selection of the…

Matched asymptotic solutions for the steady banded flow of the diffusive Johnson-Segalman model in various geometries

O Radulescu, P. D. Olmsted

We present analytic solutions for steady flow of the Johnson-Segalman (JS) model with a diffusion term in various geometries and under controlled strain rate conditions, using matc…

Two-state shear diagrams for complex fluids in shear flow

Peter D. Olmsted

The possible ``phase diagrams'' for shear-induced phase transitions between two phases are collected. We consider shear-thickening and shear-thinning fluids, under conditions of bo…

Phase Separation of Rigid-Rod Suspensions in Shear Flow

Peter D. Olmsted, C. -Y. David Lu

We analyze the behavior of a suspension of rigid rod-like particles in shear flow using a modified version of the Doi model, and construct diagrams for phase coexistence under cond…

Dynamics and flow-induced phase separation in polymeric fluids

Peter D. Olmsted

The past few years have seen many advances in our understanding of the dynamics of polymeric fluids. These include improvements on the successful reptation theory; an emerging mole…

Phase Coexistence of Complex Fluids in Shear Flow

Peter D. Olmsted, C-Y David Lu

We present some results of recent calculations of rigid rod-like particles in shear flow, based on the Doi model. This is an ideal model system for exhibiting the generic behavior…
