The process of vortex ring generation and propagation has received substantial treatment in the literature. A common ring generation geometry consists of a piston moving through tube that exits into a ...

Intrigued by a grainy video from 1992, [Destin] from Smarter Every Day decided to jump in and fund his own research into the strange phenomenon of vortex ring collisions. This hack started with a ...

The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

ONE of the commonest examples of a vortex phenomenon may be observed in the formation of smoke rings. Detailed studies of the structure of smoke rings were made many years ago by R. W. Wood 1. Smoke ...
