A turbulent boundary layer over a given geometry was studied experimentally in the framework of a EUHIT project. The geometry consists of a specifically designed ramp model, which is approximately 7m long. The model used is the LML-AVERT ramp on which the final flap was replaced by a 3.5m long flat plate. Several PIV experiments were conducted including one covering the full boundary layer thickness over a length of more than 10 boundary layer thicknesses with a good spatial resolution. The statistics show the development of a second peak characteristic of this type of flow with adverse pressure gradient and probably associated to the enhancement of very large scale motions.
