Sinopsis

High Reynolds numbers zero pressure gradient flat plate turbulent boundary layer experiments have been carried out in the large wind tunnel of Laboratoire de Mécanique de Lille using synchronized PIV systems and a hot-wire rake of 143 single probes. The experiments were performed within the WALLTURB research project to create new data on wall turbulence at large Reynolds numbers. Tested Reynolds numbers based on the momentum thickness were 19100 and 9800. Experimental details and initial results are presented in the paper.
