An experimental investigation of an axisymmetric synthetic jet generated by an oscillating piston into a cavity has been conducted performed in water using digital particle image velocimetry for the instantaneous velocity planar measurements. Depending on the jet flow parameters, a single vortex ring or a train of vortex rings characterizes the near field during the blowing phase.
