Rheology of dense fiber suspensions: Origin of yield stress, shear thinning and normal stress differences
Monsurul Khan, Rishabh V. More, Luca Brandt +1
We explain the origins of yield stress, shear-thinning, and normal stress differences in rigid fiber suspensions. We investigate the interplay between the hydrodynamic, colloidal a…

Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…

A unifying mechanism to explain the rate dependent rheological behavior in non-Brownian suspensions: One curve to unify them all
Rishabh V. More, Arezoo M. Ardekani
We propose a unifying mechanism based on the Stribeck curve for the coefficient of friction between the particles to capture the shear thinning - Newtonian plateau - shear thickeni…
