CYLINDER WAKE IMAGE

Low Reynolds Number Cylinder Wake Flow

This visualisation shows the "Mode A" flow structures in the wake of a circular cylinder. The Reynolds number is 210. The structures (blue/yellow) represent isosurfaces of streamwise vorticity (both positive and negative). An isosurface of pressure (red) is shown to highlight the Strouhal vortices in the wake. The calculation was performed with a spectral-element/spectral code. The results are in good agreement with the experiments performed by Charles Williamson at Cornell.
