Abstract
For very insect such as tiny wasp Encarsaria Formosa, Weis-Fogh found that the ‘clap-fling’ mechanism of their wings is the main cause for their large lift. In this paper, we simulate the motion numerically and analyze the generation of large lift by the wings with an unsteady incompressible flow solver based on dynamic hybrid mesh. Both one wing flap** and two wings ‘clap and fling’ are considered in the Reynolds number range of 8–128, the difference on flow structures and aerodynamic forces are compared with each other, and then high lift mechanism is analyzed.
