Shear thinning in dilute polymer solutions
The Journal of Chemical Physics, 2006 We use bead-spring models for a polymer coupled to a solvent described by multiparticle collision dynamics to investigate shear thinning effects in dilute polymer solutions. First, we consider the polymer motion and configuration in a shear flow. For flexible polymer models we find a sharp increase in the polymer radius of gyration and the fluctuations

Rheology of Emulsions Thickened by Starch Nanoparticles
Nanomaterials, 2022 The rheology of oil-in-water (O/W) emulsions thickened by starch nanoparticles is investigated here. The starch nanoparticle concentration is varied from 0 to 25 wt% based on the matrix aqueous phase. The oil concentration is varied from 0 to 65 wt%.

Lattice Boltzmann Models for Complex Fluids
, 1993 We present various Lattice Boltzmann Models which reproduce the effects of rough walls, shear thinning and granular flow. We examine the boundary layers generated by the roughness of the walls.

Laminar flow in three-dimensional square-square expansions [PDF]
, 2011 In this work we investigate the three-dimensional laminar flow of Newtonian and viscoelastic fluids through square–square expansions. The experimental results obtained in this simple geometry provide useful data for benchmarking purposes in complex three-

Characteristics of stratified flows of Newtonian/non-Newtonian shear-thinning fluids
, 2017 Exact solutions for laminar stratified flows of Newtonian/non-Newtonian shear-thinning fluids in horizontal and inclined channels are presented. An iterative algorithm is proposed to compute the laminar solution for the general case of a Carreau non ...

Universal mechanism of shear thinning in supercooled liquids
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 ...

Yield dimensionless magnetic effect and shear thinning for magnetorheological grease
Results in Physics, 2020 The effects of silicone oil viscosity (SOV), carbonyl iron particles (CIPs) weight fraction and size on the yield dimensionless magnetic effect (DME) and shear-thinning behavior for magnetorheological (MR) grease were experimentally investigated in this ...

Effect of jet-cooking on rheological properties of navy bean flour suspensions
Food Chemistry Advances, 2023 Navy beans are a gluten-free pulse containing great heathy sources for human beings. In this work, we compared the rheological properties of untreated navy bean flour suspensions (UNBFS) and jet-cooked navy bean flour suspensions (JCNBFS). Jet-cooking is

Phase-field simulations of viscous fingering in shear-thinning fluids
, 2009 A phase-field model for the Hele-Shaw flow of non-Newtonian fluids is developed. It extends a previous model for Newtonian fluids to a wide range of shear-dependent fluids.

The thinning of lamellae in surfactant-free foams with non-Newtonian liquid phase [PDF]
, 2008 Thinning rates of liquid lamellae in surfactant-free non-Newtonian gas–liquid foams, appropriate for ceramic or polymer melts and also in metals near the melting point, are derived in two dimensions by matched asymptotic analysis valid at small capillary
