Abstract
It is known that insects and aquatic animals fly or swim effectively by skillfully controlling their wings elastically deforming and vortices generated around a body. A flow field around an elastic body is treated as a coupled problem of fluids and structures (Fluid Structure Interaction Problem, FSI) and a series of phenomena, motion, structural deformation and generation / growth / development of vortices, are repeated continuously. However, impacts of elasticity on a flow field and dynamic forces have not been clarified yet. The purpose of the present study is to clarify the effect of the Young's module and airfoil configuration of the elastic flat plate by numerical simulation using ANSYS-ANSYS-CFX.
