Abstract
Many studies on the flow field around an unsteady rigid airfoil in a low Reynolds number regime have been reported. In recent years, the flow field around a moving elastic body, such as the wing of flying insects or the tail fins of water-base life forms swimming through fluids, has become a focus of attention, and its effects are beginning to be understood. In this study, we focused on the flow field around a pitching elastic thin film with low aspect ratio and performed a fluid-structure interaction analysis using ANSYS 14.5/ANSYS-CFX 14.5. We visualized an interaction of vortices shed from leading edge and wing tip on the elastic thin film. The interaction of vortices induce a fast flow in the wake and generates high thrust acting on the thin film.
