摘要

The flapping motion of a wing based on the hind wing of the Aeschna juncea dragonfly is simulated using a three-dimensional incompressible Navier-Stokes solver. The performance of the wing is investigated by variation of a number of kinematic parameters. Flapping amplitudes of between 10 and 60 deg (half-angle) and frequencies of 1 to 300 Hz are considered, resulting in a Reynolds number range of 100 to 50,000. The flapping amplitude observed for Aeschna juncea is shown to maximize the ratio of mean vertical force produced to power required.
