Title: Investigation of the law-of-the-wall for a turbulent boundary layer flow subject to an adverse pressure gradient using multi-resolution particle imaging
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 the law-of-the-wall for adverse pressure gradients. The objective of 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 at high Reynolds numbers by a joint PIV campaign of DLR and UniBw Munchen, and to investigate existing and to develop improved proposals for the law-of-the-wall in case of an adverse pressure gradient.
