Channel flows with two opposite bumps at different Reynolds numbers

Channel flow with two 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 block is for a low Reynolds number case, followed by two calculations for a midranged Reynolds number.

The second block corresponds to simulations again with midrange and high Reynolds numbers, but in contrast now for different locations of the bumps. A typical coarse mesh is shown in the following Figure.

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