Flow Patterns of a Circular Vortex Ring With Density Difference Under GravitySource: Journal of Applied Mechanics:;1972:;volume( 039 ):;issue: 004::page 869DOI: 10.1115/1.3422883Publisher: The American Society of Mechanical Engineers (ASME)
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.
