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.

Abstract: The transition of wake flow behind two non-identical tandem cylinders from a two-dimensional (2D) flow regime to a three-dimensional (3D) flow regime is investigated using direct numerical simulation. The upstream cylinder has a square cross… read more here.

Abstract: The spatial transition of the wake behind a thin pitching plate in the thrust regime is studied. The drag-to-thrust transition is seen to occur at a threshold pitching frequency which becomes smaller for higher pitching… read more here.
