Resolvent-analysis-based design of airfoil separation control [PDF]
Journal of Fluid Mechanics, 2018 We use resolvent analysis to design active control techniques for separated flows over a NACA 0012 airfoil. Spanwise-periodic flows over the airfoil at a chord-based Reynolds number of $23\,000$ and a free-stream Mach number of $0.3$ are considered at ...

Airfoil-like mechanics generate thrust on the anterior body of swimming fishes
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Many fishes have bodies shaped like a low-drag airfoil, with a rounded leading edge and a smoothly tapered trailing region, and move like an airfoil pitching at a small angle.
