Control of Deep Dynamic Stall by Duty-Cycle Actuation Informed by Stability Analysis

What is it about?

We propose a framework to reduce airfoil drag from dynamic stall. The approach employs computationally inexpensive, physics-based methods which are used to inform the position and finite duty cycle of flow actuation. The framework is assessed by testing the actuation in a high-fidelity numerical simulation environment. The physical mechanisms are then elucidated.
