Abstract

The natural flyers flap there wings for its flight. When the wings flap, flow field around the wings would be reoriented and flyers make use of it to sustain its flight. In the present study, particle image velocimetry measurements are used to capture the flow field around the rigid wings attached to a mechanical main flapping mechanism. The experiments are conducted for a kinematic asymmetry flapping of the wing with aspect ratio 1.0 and flapping frequency of 2.0 Hz in quiescent water medium. The dimensions of the wing are 40mm in chord, 40mm in span and thickness of 1.5mm. The Reynolds number is of the order of 104. The results revealed the formation of wingtip vortices, flow along the span, added mass and residual flow.
