Abstract
Description
We study the evolution of chaotic mixing in an initially stratified circular vessel. The bottom and top halves of the vessel are filled with viscoplastic and Newtonian fluids. A circular stirrer in the vessel promotes the mixing. We considered three different viscosity ratios to understand the effect of viscosity on the mixing evolution. The results reveal that as the viscosity ratio increases, the mixed region shrinks, and more time is required for mixing.
