dc.description.abstractThis paper investigates the unsteady aerodynamic features of wing-wing, wing-body and
vortex-vortex interactions in insects' flapping motions under forward flight condition. A
realistic wing trajectory, called the figure-of-eight motion, is extracted from a blowfly
(Phormia regina)s tethered flight experiment under the freestream velocity of 2.75m/s. Since
the flow field around the blowfly exhibits characteristics of low-Reynolds number flow, the
three-dimensional unsteady incompressible Navier-Stokes equations are employed as the
governing equations. In order to simulate the realistic insect flapping flight including
geometric and kinematical complexity with a sufficient level of grid quality, overset grid
technique is used. From the authors' previous researches on two- and three-dimensional
rigid wing simulation, it has been observed that the pattern of vortical flows and the
interaction of vortices play an important role in generating unsteady aerodynamic forces
and determining the propulsive efficiency of flapping motion. Detailed numerical
simulations of a blowflys wing-body motion are conducted to examine unsteady flow
features resulted from the wing-body interaction.
