Sheared active fluids: Thickening, thinning, and vanishing viscosity [PDF]

Physical Review E, 2010
We analyze the behavior of a suspension of active polar particles under shear. In the absence of external forces, orientationally ordered active particles are known to exhibit a transition to a state of non-uniform polarization and spontaneous flow. Such a transition results from the interplay between elastic stresses, due to the liquid crystallinity ...

Shear-thickening fluids in biologically relevant agents

Biorheology, 2019
BACKGROUND: The rheology of shear thickening fluids is well characterized for many physical applications, however the literature surrounding biologically or cryobiologically compatible shear thickening fluids is less well understood. OBJECTIVE: This study examined fluids consisting of corn-derived hydroxyethyl starch with a variety of sugars and ...

An empirical equation for shear viscosity of shear thickening fluids [PDF]

Journal of Molecular Liquids, 2021
Quantitative modelling of the rheology of non-Newtonian fluids requires significant empirical input due to very complex behaviour of the bulk fluid as a result of particle-scale physics of fluids. The existing rheology models are mainly limited to certain fluid dynamics conditions such as shear rate, shear stress, etc.

Blast Effects of a Shear Thickening Fluid-Based Stemming Material

Mining, 2022
The Trauzl test is widely used to measure the explosive power of a substance by determining the volume increase produced by the detonation of a tested explosive charge in the cavity of a lead block with defined quality and size. In this study, the Trauzl

Simulating the Dynamic Behavior of Shear Thickening Fluids

CoRR, 2015
While 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 the different types of non-Newtonian fluids with non-constant viscosity.
