Flow-induced scattering peak in the structure factor of polymer solutions

Research output: Contribution to journalArticle

Abstract

We demonstrate that, at low shear rates, the scattering peak in the structure factor of sheared polymer solutions results from the combined effects of advection and flow-induced concentration fluctuation enhancement. Using time-resolved small angle light scattering, the distance of the peak from the origin of the reciprocal space is shown to scale as 1/2, where is the shear rate of the flow.
