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 vortex flow in the vicinity of a wall by PIV measurements and clarified the growth and development of vortices generated in the vicinity of the wall of heaving elastic flat plate quantitatively. We clarified that vorticities of vortex generated in the vicinity of a wall of trailing edge of elastic flat plate increase rapidly when the acceleration of heaving motion becomes maximum value. Moreover, vorticities of vortex generated in the vicinity of a wall grows up until the acceleration of trailing edge becomes maximum value.
