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

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 ...

Shear thinning of a critical viscoelastic fluid [PDF]
Physical Review E, 2005 The frequency and shear dependent critical viscosity at a correlation length $ξ=κ^{-1}$, has the form $η=η_{0}κ^{-x_η}G(z_{1},z_{2})$, where $z_{1}$ and $z_{2}$ are the independent dimensionless numbers in the problem defined as $z_{1}=\frac{-iω}{2Γ_{0}κ^{3}}$ and $z_{2}=\frac{-iω}{2Γ_{0}κ_{c}^{3}}$.

Critical Shear Rate of Polymer-Enhanced Hydraulic Fluids
Lubricants, 2020 Many application-relevant fluids exhibit shear thinning, where viscosity decreases with shear rate above some critical shear rate. For hydraulic fluids formulated with polymeric additives, the critical shear rate is a function of the molecular weight and

Shear Viscosity and Shear Thinning in Two-Dimensional Yukawa Liquids [PDF]
Physical Review Letters, 2006 A two-dimensional Yukawa liquid is studied using two different nonequilibrium molecular dynamics simulation methods. Shear viscosity values in the limit of small shear rates are reported for a wide range of Coulomb coupling parameter and screening length.
