title = "Vortex filament simulation of the longitudinal vortices found in the wake of a bluff body",
abstract = "In this paper, a three-dimensional inviscid vortex filament method is used to illustrate the formation mechanism of counter-rotating longitudinal vortices found in the wake of a bluff body. A vortex filament is introduced into the velocity field of an ideal Karman vortex street, and its three-dimensional evolution is tracked in the Lagrangian frame of reference. It is demonstrated that a localized perturbation, consisting of a small displacement of the vortex filament, spreads across the span of the filament, due to self-induction, to form wave-type pattern. The 'waves' are further stretched due to the background velocity field of the vortex street, forming counter-rotating longitudinal vortices.",
