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

Flow of a Self-Similar Non-Newtonian Fluid Using Fractal Dimensions
Fractal and Fractional, 2022 In this paper, the study of the fully developed flow of a self-similar (fractal) power-law fluid is presented. The rheological way of behaving of the fluid is modeled utilizing the Ostwald–de Waele relationship (covering shear-thinning, Newtonian and ...

Mixing in shear thinning fluids [PDF]
Brazilian Journal of Chemical Engineering, 2012 In the present study, a CFD characterization of the flow generated by curved-blade impellers in a cylindrical unbaffled vessel was carried out. The tank diameter was 300 mm, with a flat bottom. The liquid height was equal to the vessel diameter. The fluids simulated have a shear thinning behavior.

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.

Wall-induced translation of a rotating particle in a shear-thinning fluid
Journal of Fluid Mechanics, 2021 Particle–wall interactions have broad biological and technological applications. In particular, some artificial microswimmers capitalize on their translation–rotation coupling near a wall to generate directed propulsion.

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.

Re-Entrant Corner for a White-Metzner Fluid
Fluids, 2021 Viscoelastic fluids can be difficult to model due to the wide range of different physical behaviors that polymer melts can exhibit. One such feature is the viscous elastic boundary layer.
