Stirring faces: mixing in a quiescent fluid

Fluid Dynamics 2012-10-16 v1

Abstract

This fluid dynamics video depicts the mixing that occurs as a two-dimensional flat plate plunges sinusoidally in a quiescent fluid. Finite-time Lyapunov exponents reveal sets that are attracting or repelling. As the flow field develops, strange faces emerge.
