Abstract

Streamwise/wall-parallel volumes of a turbulent boundary layer at Reθ= 7800 and 11800 are measured using a 4 camera (2048 × 2048 px) tomographic particle image velocimetry (Tomo-PIV) system in the turbulent boundary layer wind tunnel at the Laboratoire de Mécanique de Lille (LML). A measurement volume of 1200 × 180 × 1200 voxels was achieved, the large boundary layer provided by this tunnel (δ ≈ 0.3 m) resulting in measurements volumes of 470+× 70+× 470+and 920+×140+×920+, respectively. Volumes were reconstructed using both the standard MART algorithm and the accelerated MLOS-SMART approach (Atkinson and Soria in Exp. Fluids 47(4-5):553-568, 2009). The quality of the data acquired by these two techniques is assessed based on the mean velocity profiles, velocity fluctuations and velocity power spectra.
