Vortex Breakdown as a Catastrophe

1998
By studying swirling viscous jets, we develop a new explanation of vortex breakdown, show how solution non-uniqueness appears through cusp and fold catastrophes as the Reynolds number Re increases, and obtain analytical solutions for Re → ∞. Although inviscid theories also involve fold catastrophe, they have a strong limitation: the dependence of the ...

The Structure of Vortex Breakdown

Annual Review of Fluid Mechanics, 1978
The term 'vortex breakdown', as used in the reported investigation, refers to a disturbance characterized by the formation of an internal stagnation point on the vortex axis, followed by reversed flow in a region of limited axial extent. Two forms of vortex breakdown, which predominate, are shown in photographs.

Some Experiments with Vortex Breakdown

The Journal of the Royal Aeronautical Society, 1964
SummaryWater tunnel flow visualisation experiments on a slender delta wing have revealed some new phenomena connected with vortex breakdown. Vortex breakdown hysteresis has been found, there being two steady flow states at some incidences, one with breakdown on the wing and one without. The formation of vortex breakdown has been studied and found to be

Numerical prediction of vortex breakdown

Fluid Dynamics Research, 1988
Despite of numerous publications on breakdown, the essential details of the problem could not sufficiently be clarified in the sense that prediction of such flows can be made. While earlier investigations tried to establish criteria according to which it could be decided, whether breakdown would occur or not, more recent analyses mainly employ ...
