Flow around `CFD' at different Reynolds numbers

Flow around `CFD' characters in a circle with fixed rotational speed at different Reynolds numbers. The flow tends to some steady behaviour (low Re case), while it seems to be fully nonsteady for the higher Reynolds number cases. The corresponding coarse mesh for all calculations is plotted in the following diagram. For a detailed description of the performed flow configurations look at the corresponding pages in the `Virtual Album'.
