Abstract: Abstract The drag–thrusttransition and wake structures of a pitching foil undergoing asymmetric sinusoidal oscillation are numerically investigated for foil thickness-based Strouhal number St D = 0.1–0.3 and amplitude ratio A D = 0.5–2.0. The asymmetry… read more here.

Abstract: Reversed von Kármán streets are responsible for a velocity surplus in the wake of flapping foils, indicating the onset of thrust generation. However, the wake pattern cannot be predicted based solely on the flapping peak-to-peak… read more here.
