General Shear-Thinning Dynamics of Confined Fluids

Tribology Letters, 2002
The shear properties for a number of thin fluid films under high pressure were investigated as a function of sliding velocity (shear rate) using the surface forces apparatus. It was found that the relationship between the effective viscosity ηeff and shear rate γ in the shear-thinning regime could be expressed by a simple equation, log10ηeff=C-nlog10γ,

Shear Thinning Fluid for Shallow Fracture Formation

Volume 8: Offshore Geotechnics; Petroleum Technology
Abstract Drilling fluids (water based or oil based) are used to drill wells. Water based drilling fluid utilize fresh water, seawater, or brines. Selection of optimum chemicals are critical to maximize well’s productivity and reduces drilling cost without damaging equipment or the surrounding environment.

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 ...

Saffman-Taylor Instabilities in Shear-Thinning Fluids

In this talk, we consider a simple mathematical model of the radial injection of a shear-thinning fluid, initially occupying a circular region of some initial injection radius, which displaces a viscous Newtonian fluid within a Hele-Shaw cell. For Newtonian fluids, Saffman-Taylor instabilities are known to develop when the displacing fluid is less ...
