Abstract

The reliable prediction of low-speed flow separation of a turbulent boundary layer on a smooth surface due to an adverse pressure gradient is still an open issue. In the literature, there is no agreement on a law-of-the-wall in case of an adverse pressure gradient. We present a recent and ongoing research investigation started in the DLR internal project RETTINA is to build up a worldwide unique set of experimental data for a turbulent boundary layer flow at adverse pressure gradient obtained by a joint large-scale PIV campaign of DLR and UniBw München, and to investigate existing and to develop improved proposals for the law-of-the-wall in case of an adverse pressure gradient.
