Shear thinning and shear thickening characteristics in electrorheological fluids
Smart Materials and Structures, 2013The electrorheology (ER) of suspensions based on polystyrene/polyaniline (PS/PANI) core/shell structured microspheres and those based on disk-like zeolite particles at different electric fields and particle volume fractions have been studied, respectively.

High-performance shear thickening fluids (STFs) due to its dilatant behaviour find appositeness in any applications which require the effective dissipation of energy without losing stiffness. The nature of particles and the medium along with the particle

Composition – Property Relations in Shear Thickening Fluids
Advances in Science and Technology, 2014It was shown that fumed silica particles (FS), dispersed in polypropylene glycol (PPG), form shear thickening fluids (STF). PPGs with different molar mass were tested. The best combination of the properties (high viscosity, obtained at high shear rate) present the fluids composed of 7 nm FS and PPG 425.

Rheological Properties of Shear Thickening Fluids
2019In this study, influences of temperature and amount of solid particles in Shear Thickening Fluids (STFs) were investigated. To observe the thickening mechanism of STFs, four main characteristic terms which are viscosity profile, critical shear rate, thickening period and thickening ratio, were defined and the effects of the variable parameters on these

Dissipative structures in shear-thickening complex fluids
Physics of Fluids, 2018The main objective of this work is to demonstrate that non-local terms of the structure variable and shear-stress is a sufficient condition to predict multiple bands in rheologically complex fluids, i.e., shear-thickening fluids. Here, shear bands are considered as dissipative structures arising from spatial instabilities (Turing patterns) rather than ...

An SPH model to simulate the dynamic behavior of shear thickening fluids
Comput. Animat. Virtual Worlds, 2019While significant research has been dedicated to the simulation of fluids, not much attention has been given to exploring new interesting behavior that can be generated with different types of non‐Newtonian fluids with nonconstant viscosity.

Energy Absorption in a Shear-Thickening Fluid
Journal of Materials Engineering and Performance, 2014This study investigates energy absorption in a shear-thickening fluid (STF) containing nano-size fumed silica as a suspending material. Fumed silica particles in 20, 30, and 40 wt.% were used in polyethylene glycol and ethylene glycol. Three areas were studied, namely: energy absorption of STF pre-impregnated aramid fabric, neat STF under high-velocity

Onset of shear thickening in a simple fluid
The European Physical Journal E, 2004We report on nonequilibrium molecular-dynamics simulations of the shear-thickening transition in a simple fluid under shear. We relate the shear-thickening transition to the onset of instabilities in the flow profile and to that of dramatic variations in normal stress differences.
