Abstract

In the present work the downstream development of device induced vortices with helical symmetry embedded in wall bounded flow on a bump is studied with the aid of Stereoscopic Particle Image Velocimetry (SPIV). The downstream evolution of characteristic parameters of helical vortices is studied, displaying a linear variation of the helical parameters up to the trailing edge of the bump where the vortex experiences an abrupt transition in structure.
