"Rheology of Dense Suspensions of Non Colloidal Spheres in Yield-Stress Fluids"

ABSTRACT


Pressure-imposed rheometry is used to study the rheological properties of suspensions of non colloidal spheres in yield stress fluids. Accurate measurements for both the shear stress and particle normal stress are obtained in the dense regime. The rheological measurements are favorably compared to a model based on scaling arguments and homogenization methods. The detailed account of this study can be found in Dagois-Bohy, S., Hormozi, S., Guazzelli, E., and Pouliquen, O. (2015). Rheology of dense suspensions of non-colloidal spheres in yield-stress fluids. Journal of Fluid Mechanics, 776, R2.
