Researchers have developed a physics-guided surrogate learning approach to control turbulent wings, significantly reducing drag. This method trains policies in simulated turbulent channel flows and then deploys them zero-shot onto a NACA4412 wing section, achieving an 11.1% drag reduction. This is a notable improvement over state-of-the-art opposition control, which achieved 8.9% drag reduction. The surrogate training method offers a substantial efficiency gain, estimated at four orders of magnitude, making scalable flow control more feasible. AI
