Shear Thickening and Turbulence in Simple Fluids

Physical Review Letters, 1986
In 1984 Erpenbeck observed a shear-induced alignment of particles into strings in nonequilibrium molecular-dynamics simulations of shear flow in the hard-sphere fluid. In this paper we show that this effect arises from the use of a thermostat which assumes a stable linear velocity profile.

Flow of dilatant (shear‐thickening) fluids

AIChE Journal, 1971
AbstractThe conduit laminar flow of dilatant (shear‐thickening) fluids was investigated. It was found that such flow agreed with the Metzner‐Reed (friction factor‐modified Reynolds number) correlation previously verified only for pseudoplastic fluids. The agreement was found to hold even for cases where the flow behavior index was 2.0 or greater, which

Rheology of Magnetorheological Shear Thickening Fluids

Advanced Materials Research, 2008
This paper presents fabrication and characterizing of a new functional material, magnetorheological shear thickening fluid (MRSTF), by mixing micron-sized magnetizable particles with nano-sized silica particle based shear thickening fluid. Dynamic properties of the MRSTF were characterized by using a parallel-plate rheometer.

Shear thickening in filled Boger fluids

Journal of Rheology, 2005
Shear thickening is studied in suspensions consisting of micrometer sized polystyrene spheres dispersed in Boger fluids. In comparison with available data for suspensions in Newtonian media, shear thickening occurs at much lower volume fractions. Suspensions in normal nonlinear viscoelastic media typically do not display shear thickening at all.

Thixotropy of MR shear-thickening fluids

Smart Materials and Structures, 2010
Particle sedimentation is a key issue of conventional magnetorheological (MR) fluids. We recently fabricated MR shear-thickening fluids (MRSTF), which can work as novel MR fluids without particle settling. This merit of the material against particle settling is attributed to the thixotropy property.

Study on magnetorheological shear thickening fluid

Smart Materials and Structures, 2008
In this paper, a magnetic-field-controlled and speed-activated magnetorheological shear thickening fluid (MRSTF) is presented. We fabricated a kind of shear thickening fluid (STF) which was composed of nanosize silica particles suspended in a solvent, ethylene glycol, at high concentrations.

Shear thinning vs shear thickening in associating fluids

The Journal of Chemical Physics, 1998
When one-bond Frenkel dumbbells are allowed to dimerize, as analyzed using the Wertheim theory of association, the resulting fluid exhibits shear thinning or shear thickening behaviors. In contrast, when Gaussian chains undergo shear-assisted association, only shear thickening is possible.
