The vortex is generated from axisymmetric flow field in rotation above a fixed horizontal surface with vertical volumetric suction at the center. From left to right: (a) Laser cross-section of a spiral breakdown. The Reynolds number (G/2pn) = 1000, and the swirl number (S) = 9.0 (b) Double helix vortex disruption Re< 750, 1.5<S<3. (c) Closed bubble breakdown Re = 2500, S=2.5.
