Close-contact melting of shear-thinning fluids

Journal of Fluid Mechanics, 2023
This study aims at establishing a model for close-contact melting (CCM) of shear-thinning fluids. We presented a theoretical framework for predicting the variation of liquid melt film thickness and motion of unmelted solid for both Carreau and power-law fluids.

On the elastohydrodynamic analysis of shear-thinning fluids

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007
Realistic 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.

Flow of shear-thinning fluids in gaps

1988
Calculation 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 turbulence decay of a shear-thinning fluid

Physics of Fluids, 2017
An experimental investigation of turbulent flow in a shear-thinning fluid is presented. The experimental flow is a boundary-free, uniformly sheared flow at a relatively high Reynolds number (i.e., Reλmax=275), which decays in time. As just one example of decaying turbulence, the experiment can be thought of as a simple model of bulk turbulence in large

Instability of streaks in pipe flow of shear-thinning fluids

Physical Review E, 2013
This 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, 2018
We 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.

An investigation into the stability of a shear thinning fluid

International Journal of Engineering Science, 2009
Abstract 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 ...

Fluid Propulsion by Cilia in a Shear-thinning Fluid

2010
Fluid 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 ...

Shear thinning of a system of membranes in a fluid

Physica A: Statistical Mechanics and its Applications, 1994
Abstract 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.
