Analysis of the Yielding Behavior of Electrorheological Suspensions by Controlled Shear Stress Experiments
Volume 16 · Issue 1 © Appl. Rheol. 16 (2006) 14– 18 Abstract: The yielding behavior of two model electrorheological suspensions of uncoated silica particles and silica coated with polyaniline base in silicone oil using controlled shear rate and controlled shear stress experiments has been analyzed. The results demonstrate that unlike the uncertain dynamic yield stress values estimated from the ...
متن کاملShear-Thickening Response of Fumed Silica Suspensions under Steady and Oscillatory Shear
Suspensions of fumed silica in polypropylene glycol exhibit shear-thickening under steady shear and "strain-thickening" under oscillatory shear. Strain-thickening refers to a sharp increase in the complex viscosity eta* observed at critical combinations of strain-amplitude and frequency. Two regimes of strain-thickening behavior have been found: The first occurs at high critical strains and low...
متن کاملElectrorheological Properties of Polyaniline Suspensions
Polyaniline (PANI) was synthesized via an oxidative coupling polymerization in acid condition and dedoped in ammonium hydroxide solution. Rheological properties of the PANI/silicone oil suspensions were investigated in the oscillatory shear mode to explore the effects of electric field strength, particle concentration, and host fluid viscosity on electrorheological (ER) characteristics. The PAN...
متن کاملCrystal nucleation of colloidal suspensions under shear.
We use Brownian dynamics simulations in combination with the umbrella sampling technique to study the effect of shear flow on homogeneous crystal nucleation. We find that a homogeneous shear rate leads to a significant suppression of the crystal nucleation rate and to an increase of the size of the critical nucleus. A simple, phenomenological extension of classical nucleation theory accounts fo...
متن کاملShear viscosity and nonlinear behavior of whole blood under large amplitude oscillatory shear.
We investigated experimentally the rheological behavior of whole human blood subjected to large amplitude oscillatory shear under strain control to assess its nonlinear viscoelastic response. In these rheological tests, the shear stress response presented higher harmonic contributions, revealing the nonlinear behavior of human blood that is associated with changes in its internal microstructure...
