Channel flows over a hill at different Reynolds numbers

This simulation shows the flow through a channel in which a hill is located. The configuration is very similar to the proposed `turbulent benchmark' which can be found at

http://www.featflow.de/bench_turb/bmtext.html .

The flow tends to some steady behaviour (medium Re case), while it seems to be fully nonsteady for the high Reynolds number case. The corresponding coarse mesh (after two refinements) for all calculations is plotted in the following diagram. For a detailed description of the simulated flow configurations look at the corresponding pages in the `Virtual Album'.
