Shear-thinning and shear-thickening emulsions in shear flows [PDF]
Physics of Fluids, 2021 We study the rheology of a two-fluid emulsion in semiconcentrated conditions; the solute is Newtonian while the solvent is an inelastic power-law fluid. The problem at hand is tackled by means of direct numerical simulations using the volume of fluid method.

Mechanistic Investigation of Microdroplet Formation in High-Viscosity Shear-Thinning Hydrogel Bioinks [PDF]
GelsHigh-resolution biofabrication requires precise microscale deposition, yet drop-on-demand (DOD) inkjet bioprinting is constrained by a narrow printable viscosity window.

Maximum spreading of impacting shear-thinning and shear-thickening drops. [PDF]
Proc Natl Acad Sci U S AThe maximum spreading of an impacting liquid drop is a key metric for characterizing the fundamental fluid process of drop impact. While extensively studied for Newtonian liquids, how far a non-Newtonian drop can spread upon impacting a solid substrate remains an open question.

Particle settling in a shear-thinning, viscoelastic fluid in the presence of wall effects [PDF]
Scientific ReportsThe settling of particles in fluids is a widespread phenomenon and commonly involves accounting for the effects of walls. Particle settling and wall effects are well understood for Newtonian fluids but the consequences of non-Newtonian fluid properties ...

The Rheology behavior of Aramid and Cellulose Nanowhisker Suspensions [PDF]
Journal of Chemical and Petroleum Engineering, 2022 The flow responses of aramid and cellulose nanowhisker (fibrids) or CNCs (cellulose nanocrystal) suspended in a sulfuric acid and water respect at loadings of about 17% weight fraction was determined in transient shear flow. The effect of temperature and

Numerical simulations of blood cell flow in non-Newtonian fluid [PDF]
MATEC Web of Conferences, 2020 We investigated how non-Newtonian viscosity behavior affects the flow characteristics of blood cells. Our findings offer insight about how shear thinning affects the dispersion of liposome-encapsulated hemoglobin and red blood cells in blood. The lattice

On the shear-thinning of alkanes
Tribology Letters, 2023 Abstract The approximate power-law dependence ofthe apparent viscosity of liquids on shear rate is of-ten argued to arise from a distribution of energy barri-ers. However, recent work on the Prandtl model, whichconsists of a point mass being dragged by a damped,harmonic spring past a sinusoidal potential, revealed asimilar dependence of the ...
