Localized Blowing and Suction for Direct Control of the Crossflow Secondary Instability
The influence of localized blowing and suction on the secondary instability of highamplitude crossflow vortices (CFVs) has been investigated by means of direct numerical simulations (DNS). The growth of artificially excited high-frequency disturbances is significantly attenuated or even neutralized by blowing or suction at the wall. Two different effects have been found during the investigation...
متن کاملNumerical Simulation of Crossflow-Transition Control using Pinpoint Suction
Laminar-turbulent transition in swept-wing boundary layers is typically caused by secondary instabilities of steady crossflow vortices (CFVs). So far, suction for laminar flow control (LFC) in three-dimensional boundary layers has been applied to reduce the crossflow and thus the growth of the primary CFV modes to CFVs. We investigate the influence of strong, localized suction (pinpoint suction...
متن کاملControl of Crossflow-Vortex Induced Transition: DNS of Pinpoint Suction
Laminar-turbulent breakdown in a swept-wing boundary layer is typically caused by secondary instabilities of steady crossflow vortices (CFVs). So far, boundary-layer suction for laminar flow control in three-dimensional boundary layers has been applied to reduce the crossflow and thus the growth of the primary vortices only. We investigate the influence of strong, localized suction (pinpoint su...
