Channel flows with multiple opposite bumps at different Reynolds numbers

Channel flow with multiple narrowing sections at different Reynolds numbers. The location and heights of the two bumps are varied which results in very different, time-dependent flow patterns. In all following diagrams, the first column is for a low Reynolds number case, followed by two calculations for a midranged and a high Reynolds number. A typical coarse mesh (in fact, after two refinements!) is shown in the following Figure.

For a detailed description of the simulated flow configurations look at the corresponding pages in the `Virtual Album'.
