  An experiment conducted in the framework of the EUHIT project and designed to
characterize large scale structures in an adverse pressure gradient boundary
layer flow is presented. Up to 16 sCMOS cameras were used in order to perform
large scale turbulent boundary layer PIV measurements with a large field of
view and appropriate spatial resolution. To access the span-wise / wall-normal
signature of the structures as well, stereoscopic PIV measurements in
span-wise/wall-normal planes were performed at specific stream-wise locations.
To complement these large field of view measurements, long-range micro-PIV,
time resolved near wall velocity profiles and film-based measurements were
performed in order to determine the wall-shear stress and its fluctuations at
some specific locations along the model.
