Pre-study of different Reynolds numbers for the ASMO test car

Flow around a car at different Reynolds numbers. This simulation is a first pre-study of the flow behaviour for a recent BMBF project together with Daimler--Benz/Stuttgart. In all following diagrams, the first column is for a low Reynolds number case, followed by a calculation for a midranged Reynolds number. A typical coarse mesh is shown in the following figure.

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