STEREO-PIV MEASUREMENTS OF A TURBULENT BOUNDARY LAYER WITH A LARGE SPATIAL DYNAMIC RANGE: INFLUENCE OF THE FREE-STREAM TURBULENCE INTENSITY

Abstract : Stereo-PIV measurements of a streamwise/wall-normal plane of a turbulent boundary layer at moderate Reynolds number were carried out in a water tunnel at two different conditions of free-stream turbulence intensity (T u ∞ = 5.5%U ∞ and T u ∞ = 3%U∞). The experimental procedure involved the arrangement of 4 cameras with large CCD arrays in order to get enough spatial dynamic range to resolve most of the coherent structures in the flow. Some statistical results of the two datasets are analysed and compared.
