  • Numerical Analysis of Corrugated Wings at Low Reynolds Number Region

抄録

<p>Corrugated wings, which are cross-sectional shapes of dragonfly wing, are expected to improve aerodynamic performance due to vortices generated by unevenness shapes at low Reynolds number region. It is difficult to observe the influence of vortices generated from the unevenness by experiments. In this research, the flowfields around corrugated wings were computed using Cartesian-mesh-based Computational Fluid Dynamics (CFD), Building-Cube Method (BCM). The simulation grasped the detailed flowfield around corrugated wing, which was difficult to be visually observed by the experiment.</p>
