Keywords: Vortex wakes, jets, vortex modeling

PIV measurements behind a wing-flap model with jet simulators in a towing tank show significant jet effects on the velocity distributions and the vortex merging process. Preliminary analysis indicates that application of a well tuned jet effect may lead to reduced rolling moment upset for follower aircraft.
