Multiple vortex structures in the wake of a rectangular winglet in ground effect
Clara M. Velte, Martin O. L. Hansen, Valery L. Okulov
Patterns of vorticity in the wake of a single rectangular winglet (vortex generator) embedded in a turbulent boundary layer have been studied using Stereoscopic Particle Image Velo…
Alteration of helical vortex core without change in flow topology
Clara M. Velte, Valery L. Okulov, Martin O. L. Hansen
The abrupt expansion of the slender vortex core with changes in flow topology is commonly known as vortex breakdown. We present new experimental observations of an alteration of th…
Helical structure of longitudinal vortices embedded in turbulent wall-bounded flow
Clara M. Velte, Martin O. L. Hansen, Valery L. Okulov
Embedded vortices in turbulent wall-bounded flow over a flat plate, generated by a passive rectangular vane-type vortex generator with variable angle to the incoming flow in a…
Instabilities in the wake of an inclined prolate spheroid
Helge I. Andersson, Fengjian Jiang, Valery L. Okulov
We investigate the instabilities, bifurcations and transition in the wake behind a 45-degree inclined 6:1 prolate spheroid, through a series of direct numerical simulations (DNS) o…
