Tunable shear thickening in suspensions PNAS

2016-9-27  When a concentrated suspension is strained, its viscosity can increase radically. This behavior, known as shear thickening, can be very useful to technological applications or highly problematic in industrial processes. Suspension flow properties are typically specified at the formulation stage, meaning that they are fixed in advance rather than controlled in situ during application.

2020-3-3  Shear thickening is the increase of the apparent viscosity as shear rate or shear stress increases. This phenomenon is pronounced in concentrated (dense) suspensions of both colloidal-scale and larger particles, with an abrupt form, known as discontinuous shear thickening, observed as the maximum flowable solid fraction is approached. An overview of observed shear thickening behavior is ...

Density waves in shear-thickening suspensions

We study two well-known shear-thickening suspensions: a cornstarch suspension in water and salt (3, 19, 22, 24, 25) and monodisperse suspension of polyvinyl chloride (PVC) particles in a Newtonian solvent (Dinch) (17, 26, 27). We show that the behavior of these samples displays generic features.

The present invention relates to the thickening of pulp suspensions. A low consistency pulp suspension is fed to a pre-thickener (10) through an inlet conduit (18).A layer of thickened pulp, formed on a filter surface (22), is pushed along the filter surface by a cleaning member to the discharge end of the pre-thickener and is discharged through the outlet (20).

Shear thickening can be interpreted as the consequence of dilatancy: the system under flow wants to dilate but instead undergoes a jamming transition because it is confined, as confirmed by measurement of the dilation of the suspension as a function of the shear rate. We study the rheology of cornstarch suspensions, a non-Brownian particle system that exhibits shear thickening.

Tuning the Rheology of Nano-Sized Silica Suspensions

In this paper, a non-Newtonian fluid was fabricated dispersing nanosized silica particles in a polyethylene glycol medium. The rheology of the suspension was investigated in a stress-controlled rheometer under increasing shear rate. Based on the rheological measurements, the suspension exhibited shear thickening behavior which gives a drastic viscosity grow with the increase in the shear rate.
