Vortex wakes of a flapping foil

, 2009
We present an experimental study of a symmetric foil performing pitching oscillations in a vertically flowing soap film. By varying the frequency and amplitude of the oscillation we visualize a variety of wakes with up to 46 vortices per oscillation ...

Crystallization and Motility-Induced Phase Separation in the Flow of Active Brownian Particles Around an Obstacle [PDF]

EPJ Web of Conferences
The interaction between fluid flow and obstacles is a fundamental problem in fluid dynamics, exemplified by the Kármán vortex street and its Reynolds number-dependent instabilities.

Stratified wake of a tilted cylinder. Part 1: suppression of von Karman vortex street

, 2012
International audienceThis experimental and numerical study considers the two-dimensional stability of a circular cylinder wake, whose axis is tilted with respect to a stable density gradient. When the Reynolds number increases, the wake transitions from

Vortex-Breakdown Efficiency of Planar Regular Grid Structures—Towards the Development of Design Guidelines

Fluids
The work presented here aims to provide design guidelines to create vortex-damping structures. A design of experiment was developed to investigate the individual and combined effects of the geometrical properties of planar regular grid structures, i.e ...
