Title: Investigation of super-structures in a turbulent boundary layer flow under the influence of an adverse pressure gradient at Reθ up to 10000 using large-scale PIV
Abstract: Flow separation of turbulent boundary layer flow on a smooth surface due to an adverse pressure gradient is still an open issue. One major reason for this is that for turbulent boundary layer flows at a strong adverse pressure gradient, the description of the mean flow using wall-laws, the characterization of the Reynolds stresses and the mechanisms
of momentum exchange in terms of coherent structures (hairpin-hypothesis, sweepstreak-interaction, super-structures) are still unresolved problems, see.
