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.

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.

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.

Propulsion of an elastic filament in a shear-thinning fluid
Soft Matter, 2021 Viaa simple elastic swimmer actuated magnetically, we present a first study to examine how shear-thinning rheology impacts the fluid-structure interaction and hence the elastohydrodynamic propulsion performance at low Reynolds numbers.

Rheology of a Dilute Suspension of Aggregates in Shear-Thinning Fluids [PDF]
Micromachines, 2020 The prediction of the viscosity of suspensions is of fundamental importance in several fields. Most of the available studies have been focused on particles with simple shapes, for example, spheres or spheroids. In this work, we study the viscosity of a dilute suspension of fractal-shape aggregates suspended in a shear-thinning fluid by direct numerical

Modelling of Power-Law Fluid Flow Inside a Piezoelectric Inkjet Printhead
Sensors, 2021 Piezoelectric three-dimensional inkjet printing has been used to manufacture heterogeneous objects due to its high level of flexibility. The materials used are non-Newtonian inks with complex rheological properties, and their behavior in the context of ...

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.

Degassing cascades in a shear-thinning viscoelastic fluid [PDF]
Physical Review E, 2011 We report the experimental study of the degassing dynamics through a thin layer of shear-thinning viscoelastic fluid (CTAB/NaSal solution), when a constant air flow is imposed at its bottom. Over a large range of parameters, the air is periodically released through series of successive bubbles, hereafter named {\it cascades}.
