• Dynamics of a vortex ring generated from a nozzle fixed on the top of a cylindrical water tank is investigated using UVP (Ultrasound Velocity Profiler). The instantaneous velocity profiles on three ultrasound beams are obtained to reconstruct two-dimensional structure of vortex ring, which alters with changing the piston speed and the piston stroke. The translational velocity, the diameter, and the length of the vortex ring are evaluated from the two-dimensional velocity field as function of dimensionless piston stroke and Reynolds number.
