Effects of interval of spanwise-modulated local forcing on mechanisms of flow separation control

Research output: Contribution to journalConference articlepeer-review

Abstract

We investigate the effects of the spanwise-modulation interval of local forcing on the mechanisms of flow separation control around a two-dimensional hump. It is shown that a spanwise modulation of y = 0:08 maximally increases the three-dimensional velocity fluctuations and leads to reattachment. Static local-forcing is assumed to promote the lift-up effects of the bypass transition of the streaks. Perturbation growth might be dependent on the spanwise interval of the forcing.
