Extra dissipation and flow uniformization due to elastic instabilities of shear-thinning polymer solutions in model porous media
We study flows of hydrolized polyacrylamide solutions in two dimensional porous media made using microfluidics, for which elastic effects are dominant. We focus on semi-dilute solutions (0.1%–0.4%) which exhibit a strong shear thinning behavior. We systematically measure the pressure drop and find t...
