Synthetic jets are useful fluid devices with several industrial applications. In this study, we
use the flow fields generated by two synchronously operating synthetic jets and simulated …

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 …

A new methodology has been devised to simulate the aerodynamic wake of an airliner
during cruise flight using Reynolds-averaged Navier-Stokes (RANS) and Large Eddy …

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

A system of stream-wise vortices has been created using a grid of swirling elements with
alternating orientations (like a chessboard). The particle image velocimetry method has …

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 …

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

The transient dynamics of a wake vortex, modelled by a strong swirling $ q $-vortex, are
examined with an emphasis on exploring optimal transient growth constructed by …

The early-time growth of an individual vortex in a wake vortex pair is explored, focusing on
its linear stability and transient growth, which are meaningful for understanding the lifespan …

The impact of freestream turbulence (FST) generated by an active turbulence grid (ATG) on
the aerodynamic performance and behavior of a wingtip vortex in the near wake of a NACA …
