Rheological properties of hydroxypropylmethyl cellulose/sodium dodecylsulfate mixtures [PDF]
Journal of the Serbian Chemical Society, 2014 Rheological properties of mixtures of hydroxypropylmethyl cellulose (HPMC), a nonionic associative cellulose ether, and sodium dodecylsulfate (SDS), an anionic surfactant, were investigated by viscosity measurements performed at different shear rates (0 ...

Numerical Well Test Analysis for Polymer Flooding considering the Non-Newtonian Behavior
Journal of Chemistry, 2015 Well test analysis for polymer flooding is different from traditional well test analysis because of the non-Newtonian properties of underground flow and other mechanisms involved in polymer flooding.

Shear thinning and thickening of cemented paste backfill
Applied Rheology, 2019 Cemented paste backfill (CPB) is considered to be a concentrated suspension in which tailings are bonded together by the hydraulic binder and water, and it has a high solid volume concentration (≥50 vol.%).

Shear-thinning in dense colloidal suspensions and its effect on elastic instabilities: from the microscopic equations of motion to an approximation of the macroscopic rheology [PDF]
, 2015 In the vicinity of their glass transition, dense colloidal suspensions acquire elastic properties over experimental timescales. We investigate the possibility of a visco-elastic flow instability in curved geometry for such materials.

Flow and hydrodynamic shear stress inside a printing needle during biofabrication.
PLoS ONE, 2020 We present a simple but accurate algorithm to calculate the flow and shear rate profile of shear thinning fluids, as typically used in biofabrication applications, with an arbitrary viscosity-shear rate relationship in a cylindrical nozzle.

Shear flow effects on phase separation of entangled polymer blends [PDF]
, 1998 We introduce an entanglement model mixing rule for stress relaxation in a polymer blend to a modified Cahn-Hilliard equation of motion for concentration fluctuations in the presence of shear flow.

Taylor-vortex flow in shear-thinning fluids [PDF]
Physical Review E, 2019 This paper deals with the Taylor-Couette flow of shear-thinning fluids. It focuses on the first principles understanding of the influence of the viscosity stratification and the nonlinear variation of the effective viscosity μ with the shear rate γ[over ̇] on the flow structure in the Taylor-vortex flow regime.
