Abstract

This paper concerns the study of the secondary structures generated in the wake of a wall mounted rectangular vane, commonly referred to as a vortex generator. The study has been conducted by Stereoscopic PIV measurements in a wind tunnel and supplementary flow visualizations in a water channel. The results show that the vane produces not only the anticipated primary vortex, but at least five vortex structures. Further, the vorticity map can be subject to various regimes, showing a dependency on the circulation of the primary vortex and the height of its center above the wall.
