Flow Characteristics of Solid Particle Suspensions.

Elasticity of dilatant particle suspensions during flow.

Dense suspensions under sufficiently high shear stress can exhibit a dramatic transition to a solidlike state. This is known as extreme shear thickening and is sometimes accompanied by dilatancy. This behavior is contradictory; the material is solidlike but only when flowing. To probe the elasticity of the dilatant state, we measure the transient inertio-elastic oscillations that occur in respo...

Particle dispersion in sheared suspensions: Crucial role of solid-solid contacts

Studies on Solid-liquid Suspensions Flow by Ultrasounds

This work aimed to contribute to the modelling of slurry flows in horizontal pipes supported by experimental data gathered in a well instruments pilot rig. An ultrasonic sensor system was inserted in the pipe in order to calculate the slurry velocity profiles using a time domain correlation method. Effects of particles concentrations and slurry flow rates were investigated. A comparison of the ...

Unsteady flow and particle migration in dense, non-Brownian suspensions

We present experimental results on dense corn-starch suspensions as examples of non-Brownian, nearly hard particles that undergo continuous and discontinuous shear thickening (DST) at intermediate and high densities, respectively. Our results offer strong support for recent theories involving a stress-dependent effective contact friction among particles. We show, however, that in the DST regime...
