Swimming efficiency in a shear-thinning fluid [PDF]
Physical Review E, 2017 Micro-organisms expend energy moving through complex media. While propulsion speed is an important property of locomotion, efficiency is another factor that may determine the swimming gait adopted by a micro-organism in order to locomote in an ...

Mixing Enhancement of Non-Newtonian Shear-Thinning Fluid for a Kenics Micromixer. [PDF]
Micromachines (Basel), 2021 In this work, a numerical investigation was analyzed to exhibit the mixing behaviors of non-Newtonian shear-thinning fluids in Kenics micromixers. The numerical analysis was performed using the computational fluid dynamic (CFD) tool to solve 3D Navier ...

Rapid wetting of shear-thinning fluids [PDF]
Physical Review Fluids, 2022 Using experiments and numerical simulations, we investigate the spontaneous spreading of droplets of aqueous glycerol (Newtonian) and aqueous polymer (shear-thinning) solutions on smooth surfaces. We find that in the first millisecond the spreading of the shear-thinning solutions is identical to the spreading of water, regardless of the polymer ...

Squirming through shear-thinning fluids [PDF]
Journal of Fluid Mechanics, 2015 Many micro-organisms find themselves immersed in fluids displaying non-Newtonian rheological properties such as viscoelasticity and shear-thinning viscosity. The effects of viscoelasticity on swimming at low Reynolds numbers have already received considerable attention, but much less is known about swimming in shear-thinning fluids.

Sedimentation of fractal aggregates in shear-thinning fluids [PDF]
Applied Sciences, 2020 Solid–liquid separation is a key unit operation in the wastewater treatment, generally consisting of coagulation and flocculation steps to promote aggregation and increase the particle size, followed by sedimentation, where the particles settle due to the effect of gravity.

Lattice Boltzmann simulations of a viscoelastic shear-thinning fluid [PDF]
Journal of Chemical Physics, 2015 We present a hybrid lattice Boltzmann algorithm for the simulation of flow glass-forming fluids, characterized by slow structural relaxation, at the level of the Navier-Stokes equation. The fluid is described in terms of a nonlinear integral constitutive
