| Popis: | Flow visualization and velocity measurements are performed in order to investigate the unsteady nature of vortex breakdown location over a delta wing. The results indicate that the fluctuations of vortex breakdown location occur at much lower frequencies than the frequency of the hydrodynamic instability of the flow in the wake of the vortex breakdown. It is suggested that the helical mode instability does not influence the unsteady nature of breakdown location. |
