Mixing dynamics and transport mechanisms during laminar stirring flows
Mohammad Reza Daneshvar Garmroodi, Ida Karimfazli
We investigate laminar mixing of a passive dye in an infinite, two-dimensional domain filled with a Newtonian fluid by simulating a cylindrical stirrer that rotates at constant spe…

Yield-Stress Fluid Mixing: Localization Mechanisms and Regime Transitions
Mohammad Reza Daneshvar Garmroodi, Ida Karimfazli
We explore the mechanisms and regimes of mixing in yield-stress fluids by simulating the stirring of an infinite, two-dimensional domain filled with a Bingham fluid. A cylindrical…

Pattern formation in coiling of falling viscous threads: Revisiting the geometric model
Will Sze, Eusebius J. Doedel, Ida Karimfazli +1
The "Fluid Mechanic Sewing Machine" creates periodic patterns through the coiling nature of a viscous fluid falling onto a moving surface. At relatively moderate heights, the repor…
