The phenomenon of vortex rings can be observed in some aquatic animals producing propulsion, in oil drilling and gaseous pollution releases. Vortex rings in this laboratory study are generated by pushing a piston through a tube with an orifice opening in water. In this paper, turbulent vortex rings are studied by means of Stereoscopic Particle Image Velocimetry (PIV). Typical turbulence quantities e.g. the turbulent stress distribution can be visualized after some mathematical processes.
