The eigen-oscillations of the turbulent vortex ring (Re=85,000)
Visualization of fast nonstationary phenomena in a turbulent vortex ring
This movie shows several periods of the eigen-oscillations of the turbulent vortex ring (Re=85,000). It is obtained by processing the frames of a high-speed drum-type camera (10,000 frames per second).
