Flow over a hill at high Reynolds number

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 flows shows a very complex behaviour with locally varying structures in space and time.

  Visualization via distribution of the temperature in the flow field, starting from the heated walls (first, shaded, 2.9 MB, second, shaded with a different color map, 3.8 MB, third as a zoom, 9.6 MB), or via starting particles at the inlet (fourth and fifth with different color maps, shaded, 3.1 MB and 3.9 MB).
