Comparison of different shapes (with/without wind shield or cargo, street version) for trucks at low Reynolds number

Short description and remarks

Short description and remarks

Flow around a truck at low Reynolds number, starting from rest. This simulation is part of a comparative study (by students during the FEATFLOW Praktikum 1995/96 at Heidelberg) with the aim to figure out the influence of the wind shield on the top of the truck, for different configurations (see also the results for the higher Reynolds number situations). In all following diagrams, the first column is for a truck with wind shield and cargo, followed by a calculation for a shape without wind shield, but still with cargo, and finally for a truck without wind shield and without cargo! 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'.
