Abstract

The structure of a tripped zero-pressure gradient boundary layer has been measured using particle image velocimetry (PIV). This paper describes the PIV experiment and the coherent structures which are identified from instantaneous streamwise wall-normal velocity fields. More than 340 large-format PIV photographs were taken at three Reynolds numbers ranging between 930 <Reθ<6845, The instantaneous velocity fields are used to examine in detail the structure of the turbulent boundary layer in the overlap region, the wake region and the super-layer. The results are consistent with the model that the turbulent boundary layer contains horseshoe and hairpin vortices.
