Turbulent Plane Channel Flow: Velocity Perturbations

The figures below show velocity perturbtion isocontours in streamwise-spanwise planes of a plane channel. The friction Reynolds number is 590; the images show one period of one snapshot of the fully-spectral computation of the flow-field, i.e. 3700x1850 wall units. The numerical resolution - as well as the data used in the image - is 6x3 wall units. Dark shading indicates low velocity. The colormap varies from image to image.
