Fluid mechanics

the short-wave bending instability of a vortex ring, in which azimuthal waves grow on the ring core and lead to its breakdown.

In fluid mechanics, Widnall instability refers to the short-wave bending instability of a vortex ring, in which azimuthal waves grow on the ring core and lead to its breakdown. This meaning comes from Widnall (1974) in Journal of Fluid Mechanics.[1]
