Abstract

In the present work the predictive capabilities of different turbulence models for active flow control applications by means of vortex generator jets are evaluated by comparing numerical predictions with experimental data. With suitable turbulence model, the influence of orientation of actuator and jet velocity ratio are studied for a round jet actuator on a flat plate with zero pressure gradient. Finally, a two-element high-lift airfoil with a pair of vortex generator jets on the leading-edge of the main wing is studied with an emphasis on the interaction of longitudinal vortices with boundary layer under adverse pressure gradient.
