Interesting Dynamics of Drops and Filaments
in Stokes Flow

Abstract
Fluid flows with low Reynolds numbers have a wide
range of applications. In this talk I
will focus on interesting dynamics of emulsion drops and slender filaments in
creeping flows. Emulsion drops with high
viscosity are found to behave in hysteretic fashions, and chaotic dynamics may
be found as a result. Interesting
dynamics of a slender filament in Stokes flows is also found: it flexes, swims,
and ties knots onto itself due to the elasticity. I will briefly summarize the numerical scheme
specifically designed to accurately capture these complex dynamics.
