Shear thickening of dense suspensions in the limit of jamming

ORAL

Abstract

In shear thickening suspensions, viscosity appears to increase when the shear rate increases. In this work, we focus on the shear thickening phenomenon that occurs in the limit of jamming. We have designed a model non-Brownian suspension to experimentally study this phenomenon. We have developed a series of comprehensive rheometry tests to provide a physical understanding of the problem. We provide a closure for shear stresses in the limit of jamming and we test this closure by studying boundary driven flows of dense suspensions
