Abstract

To characterize the turbulent boundary layer evolution in the LMFL wind tunnel, two experiments of velocity measurement by PIV were carried out. A first campaign was done based on a high magnification 2C2D PIV in the near wall region in order to capture the near wall scales and the mean gradient. A second experiment of stereo PIV using two systems was carried out to measure the full boundary layer with a good spatial resolution. By merging these two experiments, a good characterization can be made at 3 stations along the wind tunnel and for three free-stream velocities.
