Many researches on flow field around the rigid moving airfoils have examined. In particular, the vortex streets behind the rigid moving airfoils have been clarified by experimental and numerical approaches. However, the flow fields and the dynamic forces on the elastic moving airfoils have not been understood sufficiently because of their fluid-structure coupled problem. Especially, the impact of elastic deformation effects on the flow fields and the dynamic forces have not been clarified. In this study, we investigate the velocity gradient in the vicinity of the wall of elastic moving airfoils with bending stiffness and their dynamic fluid forces.
