| description abstract | The evolution of a circular vortex ring with a density 1.5 times of the ambient fluid under gravity was investigated. Three distinct patterns, namely, laminar, wavy, and turbulent, were observed. It is found that approximately as Nre > 2000, the vortex becomes turbulent, as Nre < 1500, laminar but to disintegrate into subrings. The stability curve was determined. | |
