Universal mechanism of shear thinning in supercooled liquids [PDF]
Communications PhysicsSoft glassy materials experience a significant reduction in viscosity η when subjected to shear flow, known as shear thinning. This phenomenon is characterized by a power-law scaling of η with the shear rate $$\dot{\gamma }$$ γ ° , $$\eta \propto {\dot ...

Inkjet printing of non-Newtonian fluids [PDF]
, 2011 Jet breakup is strongly affected by fluid rheology. In particular,small amounts of polymer can cause substantially different breakup dynamics compared to a Newtonian jet, influencing in-flight fragmentation and detachment from the nozzle.

Analysis of the Shear-Thinning Viscosity Behavior of the Johnson–Segalman Viscoelastic Fluids
Fluids, 2022 This paper presents a numerical comparison of viscoelastic shear-thinning fluid flow using a generalized Oldroyd-B model and Johnson–Segalman model under various settings. Results for the standard shear-thinning generalization of Oldroyd-B model are used

Effect of Shear-Thinning Property on the Energy Performance and Flow Field of an Axial Flow Pump
Energies, 2022 In the chemical and petroleum industry, the axial flow pump is widely used for the circulation pipeline system, and most of the transportation mediums are the shear-thinning non-Newtonian fluids.

Interfacial Dynamics of Miscible Displacement of Shear-Thinning Fluid in a Vertical Channel
Fluids, 2023 The displacement of a shear-thinning fluid by a denser and less viscous Newtonian fluid in a vertical duct is investigated using experiments and numerical simulations. We study how shear-thinning and increased viscosity contrast between the fluids affect

Shear-thinning and shear-thickening emulsions in shear flows [PDF]
Shear-thinning and shear-thickening emulsions in shear flowsWe 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.

Pulsatile flow of shear-dependent fluid in a stenosed artery [PDF]
Theoretical and Applied Mechanics, 2012 This paper aims to investigate the blood flow in a bell-shaped constricted rigid tube, modeled as stenosed artery. The flow is assumed to be axi-symmetric, laminar and of oscillatory type.

Shear thinning and shear thickening of a confined suspension of vesicles [PDF]
Physical Review E, 2018 Widely regarded as an interesting model system for studying flow properties of blood, vesicles are closed membranes of phospholipids that mimic the cytoplasmic membranes of red blood cells. In this study we analyze the rheology of a suspension of vesicles in a confined geometry: the suspension, bound by two planar rigid walls on each side, is subject ...
