Nonlinear Electrophoresis of Microparticles in Shear Thinning Fluids
LangmuirThe nonlinear electric field dependence of particle electrophoresis has been demonstrated to occur in Newtonian fluids for highly charged particles under large electric fields. It has also been predicted to arise from the rheological effects of non-Newtonian fluids even at small electric fields.

Flow of shear-thinning fluids in gaps
1988Calculation procedures are presented for the laminar flow of generalized Newtonian fluids through an eccentric axial gap and through an axisymmetric casing of arbitrary shape. Experimental and numerical data are compared for a fluid with the viscosity function described by the Ellis law. Good agreement is found in both cases.

On the elastohydrodynamic analysis of shear-thinning fluids
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007Realistic prediction of the characteristics of the elastohydrodynamic lubrication (EHL) contact requires consideration of the appropriate constitutive equation for the lubricant. In many applications, the lubricant exhibits a shear-thinning behaviour which significantly affects the film thickness.

An investigation into the stability of a shear thinning fluid
International Journal of Engineering Science, 2009Abstract Experiments [T. Mullin, R.R. Kerswell (Eds.), Laminar Turbulent Transition and Finite Amplitude Solutions, Proceedings of the UITAM Symposium, Springer, Bristol, UK, Dodrecht, 2005.] show that transition to turbulence can start at Reynolds numbers lower than it is predicted by the linear stability analysis – the subcritical transition to ...

Instability of streaks in pipe flow of shear-thinning fluids
Physical Review E, 2013This study is motivated by recent experimental results dealing with the transition to turbulence in a pipe flow of shear-thinning fluids, where a streaky flow with an azimuthal wave number n=1 is observed in the transitional regime. Here, a linear stability analysis of pipe flow of shear-thinning fluids modulated azimuthally by finite amplitude streaks

Breakup dynamics of toroidal droplets in shear-thinning fluids
Physical Review E, 2018We use toroidal droplets to study the breakup dynamics of a Newtonian liquid jet in the presence of rheologically nonlinear materials. We find that the droplets resist breakup for times that are longer than those in the presence of Newtonian liquids.

Fluid Propulsion by Cilia in a Shear-thinning Fluid
2010Fluid propulsion by natural cilia is governed by their asymmetric motion. For artificial cilia driven by an external force, this asymmetry comes from the shape of the applied force and the initial shape of the cilium. For shear-thinning liquids such as saliva, which are deformation rate dependent, the motion can also become asymmetric due to different ...

An adaptive remeshing strategy for shear-thinning fluid flow simulations
Computers & Chemical Engineering, 2004Abstract In the last few years, a team effort has allowed the development of a very general adaptive finite element solution procedure which can be applied to a large variety of problems. In this paper, this complete strategy is presented and applied to the solution of three-dimensional shear-thinning fluid flow problems. Carreau–Yasuda and power-law

Shear thinning of a system of membranes in a fluid
Physica A: Statistical Mechanics and its Applications, 1994Abstract The steady state shape of a membrane in shear flow is considered numerically beyond the regime of small deformations. The effective viscosity of a dilute system of membranes immersed in a liquid is calculated. The decrease in the effective viscosity as a function of the shear rate (shear thinning) is demonstrated explicitly.
