A number of studies on wake structures and the characteristics of dynamic thrusts of an unsteady airfoil have been reported over the years. However, behaviors of vortices that form wake structures and processes from generation to development have not been clarified. The authors measured a flow field in the vicinity of a wall including boundary layers by PIV measurements and clarified the growth and development of vortices generated in the vicinity of the wall quantitatively. We clarified that vortex flow in the vicinity of the wall is different between the rigid NACA0010 and elastic NACA0010. Vortices generated in the vicinity of the wall of elastic NACA0010 develop sufficiency on the wall of and they are separated from the trailing edge far from the center point of heaving amplitude.
