Vortex structures of the vortex rings ejected toward the free surface of water were studied by means of flow visualization experiments. The formation processes of secondary vortices induced by the primary vortex ring, which was ejected in a circular pipe or ejected along the surface of a flat plate, were observed to clarify the complex interaction of the vortex rings with sidewalls and the free surface of water. The wavy instability of the primary vortex ring interacting with the solid walls and the free surface is found to cause various 3D vortex structures of the vortex rings with secondary vortices. The 3D vortex structures were shown in the figure of cross section of the vortices as well as in the 3D images composed from a series of video pictures of the vortex ring passing through a sheet of illuminated layer of laser light.
