Three-dimensional flow structure on a maneuvering wing

Unsteady plunging (heaving) of a wing in the form of a flat plate can give rise to pronounced axial flow in the small-scale leading-edge vortex, during its initial stage of formation. Opposing axial flows along the vortex interact at the plane of symmetry giving rise to large-scale patterns of streamwise-oriented vorticity, which can dominate the tip vortices over part of the oscillation cycle.
