Summary

This paper presents results from flow simulations about a simple train model to be used in an upcoming experiment. The simulations are made with the unstructured Navier-Stokes solver TAU employing hybrid grids. The influence of wind tunnel walls as well as a ground plate with and with out a boundary layer is examined. The results obtained so far indicate that the influence of the wind tunnel wall can be neglected in the computation, while the boundary layer on the ground plate might become critical in the experiment. Furthermore the influence of cross wind on the train is studied by yawing the train up to 30° to the oncoming flow.
