摘要

The present contribution reports on a direct numerical simulation (DNS) of a fully turbulent boundary layer that undergoes separation due to the presence of a pressure gradient at a moderate Reynolds number. The variation of the free-stream velocity has been chosen according to an experiment of Kalter and Fernholz (1994). Because of limited computational resources, the momentum thickness Reynolds number at the reference position is Re_θ = 870 which is about half as large as that of the experiment. Nevertheless, a comparison of global values and first and second order statistics shows good agreement between simulation and experiment.
