A simulation study demonstrating the importance of large-scale trailing vortices in wake steering [PDF]
Wind Energy Science, 2018 In this paper, we investigate the role of flow structures generated in wind farm control through yaw misalignment. A pair of counter-rotating vortices is shown to be important in deforming the shape of the wake and in explaining the asymmetry of wake ...

Wake-Fin Tailoring for Projectile Steering
28th AIAA Applied Aerodynamics Conference, 2010 Proof-of-concept experiments and computational simulations were conducted to investigate the feasibility of an active flow control concept, called wake-fin tailoring (WaFT), to improve the steering performance and attitude control of projectiles. The concept is based on the use of mechanical flow control actuators located at a position well upstream of
