Abstract

In this study, the aerodynamic characteristics of dragonfly wing corrugation in hovering flight are investigated using the computational fluid dynamics (CFD) methods. Three corrugated cross sections of the right forewing of a dragonfly (Aeshna cyanea) are considered. The effects of wing corrugation are identified by comparing the aerodynamic differences between the corrugated and the corresponding smoothed wing sections, and the underlying flow mechanisms of the corrugation effects are revealed by analyzing the flow fields and surface pressure distributions of the wings. The results show that the wing corrugation has little effects on aerodynamic performance of wings. The time histories of aerodynamic forces of the corrugated wings are very close to those of the smoothed wings. The flow information indicates that the corrugated and smoothed wings have approximately the same vorticity around the wings.
