The essence of generating vortex-within-a-vortex structures behind forked caudal fins
AIP Advances, 2022 This work focuses on vortex-within-a-vortex (VV) structures behind three different shapes of forked caudal fin with a heaving-pitching motion. The results show that the synchronization of trailing-edge vortex separation and the shedding of the leading ...

The Aerodynamic Effect of an Alula-like Vortex Generator on a Revolving Wing
Biomimetics, 2022 An alula is a small structure of feathers that prevents birds from stalling. In this study, the aerodynamic effect of an alula-like vortex generator (alula-VG) on a revolving wing was investigated using the PIV technique in a water tank. The alula-VG was

Aerodynamic performance of dragonfly wing model that starts impulsively: how vortex motion works
Journal of Fluid Science and Technology, 2023 The cross-section of dragonfly wings has corrugated structures. In particular, the leading-edge side of the wing consists of V-shaped structures. According to previous studies, a corrugated wing may exhibit high aerodynamic performance at low Reynolds ...
