The role of the second normal stress difference in rod-climbing effect

Rishabh More

The Weissenberg (rod-climbing) effect, i.e., the rise of a viscoelastic fluid along a thin rotating rod, has long served as a canonical demonstration of elasticity and normal-stres…

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…
