Velocity contrasts enhancement for shear thinning solutions flowing in a rough fracture [PDF]

, 2007
Flow and transport are studied in transparent model fractures with rough complementary self-affine walls with a relative shear displacement $\vec{u}$. The aperture field is shown to display long range correlations perpendicular to $\vec{u}$: for flow in ...

Flow curves of colloidal dispersions close to the glass transition: Asymptotic scaling laws in a schematic model of mode coupling theory

, 2008
The flow curves, viz. the curves of stationary stress under steady shearing, are obtained close to the glass transition in dense colloidal dispersions using asymptotic expansions in a schematic model of mode coupling theory.

Laminar flow in three-dimensional square-square expansions [PDF]

, 2011
In this work we investigate the three-dimensional laminar flow of Newtonian and viscoelastic fluids through square–square expansions. The experimental results obtained in this simple geometry provide useful data for benchmarking purposes in complex three-

Role of B2O3 on structure and shear-thinning property in CaO–SiO2–Na2O-based mold fluxes

High Temperature Materials and Processes, 2019
Most traditional mold fluxes are Newtonian fluids, and their constant viscosity has certain limitations in continuous casting. A new non-Newtonian fluid mold flux with shear-thinning behavior, i.e., a mold flux with a relatively high viscosity at lower ...

Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]

, 2009
The effect of microchannel aspect ratio (channel depth/channel width) on residence time distributions and the axial dispersion coefficient have been investigated for Newtonian and shear thinning non-Newtonian flow using computational fluid dynamics.

Milli-PIV rheology of shear-thinning fluids [PDF]

Journal of Non-Newtonian Fluid Mechanics, 2012
Milli-Particle Image Velocimetry (Milli-PIV), which is an application of the standard PIV has been developed to measure the velocity distribution of complex fluids in a millimetric Hele-Shaw cell. A laser sheet is sent perpendicularly to the cell and the camera observes the PIV images via an internal optical prism.
