An Analytical Investigation of Vortex Breakdown

[摘要] It is well-known that the separation of flow from the leading edges of a highly swept wing at a high angle of attack results in the creation of a well-ordered vortical flowfield above the upper surface of the wing; the sudden disruption of this flowfield that occurs at a critical angle of attack limits the flight regime for such a wing. Although considerable research effort has been directed towards this "vortex breakdown" phenomenon, there is as yet no widely accepted explanation for its occurrence, nor a consistently effective means for its prevention or control.
