Shear-Induced Structure and Velocity Fluctuations in Particulate Suspensions Probed by Ultrasonic Correlation Spectroscopy and Rheology

We report measurements of the steady-state shear viscosity and shear-induced structure of neutrally buoyant non-Brownian particulate suspensions. Four distinct types of behavior were found for the viscosity of the suspensions as the shear rate and concentration were varied. Possible interpretations...

Description
Summary:We report measurements of the steady-state shear viscosity and shear-induced structure of neutrally buoyant non-Brownian particulate suspensions. Four distinct types of behavior were found for the viscosity of the suspensions as the shear rate and concentration were varied. Possible interpretations of the data in term of the shear-induced structure of the suspensions are discussed. A new ultrasonic technique was used to determine the relaxation time required for the particles to come to rest after the shear rate is set to zero.
