Abstract

Stable attachment of the Leading Edge Vortex (LEV) is responsible for stable flight in insects. The LEV structure over a flapping insect wing is influenced by several geometrical and kinematic parameters. In our study, it is shown that a change in the wing Reynolds number (Re) affects the LEV structure. A comparison with previous numerical results also revealed the effect of the wing offset in the experiments. The flow structure is investigated using the Particle Image Velocimetry (PIV) technique. A scanning PIV system is being developed to capture the 3-D flow structures.
