Abstract

Direct numerical simulations of the effects of a cylindrical roughness element in the laminar 3-d boundary layer on the upper surface of a swept wing are performed. The roughness element generates streamwise vortices, where one is persistently growing in streamwise direction due to crossflow instability. By varying the roughness height, the onset of secondary instability of this crossflow vortex and ultimate transition to turbulence varies also in streamwise direction. When reaching the “effective”, i.e. the flow-tripping roughness height, the linear crossflow-instability regime is bypassed and breakdown to turbulence occurs in close vicinity to the element due to a global instability.
