In the above equation, σ 0 is the value of yield stress and η C is the value of Casson viscosity that is related to a high shear rate viscosity. Herschel-Bulkley model is another model used in yield ...

Flow curves of polymer melts (the graph of viscosity versus shear rate in the log-log scale) have two distinct behaviors governed by Newtonian and Power law. The Newtonian behavior dominates at very ...

Bubbles often vigorously spout out when we pour or shake a bottle of champagne or cola. When on a boat, we also see that enormous gas bubbles are formed around a rotating screw. These flow-induced ...
