The decay of trailing vortices is a fundamental problem in fluid mechanics and constitutes
the basis of control applications that intend to alleviate the wake hazard. In order to …

The interaction of a line vortex with a collinearly aligned jet is a prototypical configuration for
various important applications in aeronautics. The purpose of this study is to analyze the …

Wingtip vortices have been proven to be detrimental to both aircraft efficiency and safety due
to their adverse effects such as wake hazard, blade vortex interaction noise and induced …

Wakes of upswept afterbodies are often characterized by counter-rotating streamwise vortex
pairs which meander in space. One application concerns aft regions of cargo aircraft, which …

Different analytical vortex models have been developed to characterize the evolution of
wingtip vortex. However, their effect on the instability characteristics has not been well …

The vortex dynamics of the tip vortices on oscillating wings in periodic and transient
plunging motions are investigated via three-dimensional velocimetry measurements in a …

Vortex meandering is often characterized by seemingly stochastic motions of the vortex core.
An elucidation of the underlying mechanisms of core movement aids not only in …

Meandering designates the main manifestation of unsteady vortex dynamics observed in
experiments. This study has the twofold objective to (i) develop a theoretical model …

Coherent vortices are important building blocks of complex flows on all scales, governing
dynamics in various applications from geophysics over engineering to the coherent …

We conducted experiments using a single non-deformed and two spanwise deformed wing
models for a constant chord-based Reynolds number, R e= 20× 10 3⁠. We carried out all …
