2010-Vortices

From McGill University Physics Department Technical Services Wiki

We investigate the effect of flowing water past immersed bodies. It produces a pattern in the fluid known as Von Kármán vortex streets that depends upon three parameters: Reynolds, Roshko and Strouhal numbers. We use stratification to isolate the formation of the wakes on a 2-D plane, allowing us to capture movement with a camera. We study the effects of speeds and cylinder diameters on the wake's properties.
