The Relationship Between Near- and-Far-Field of Vortex Wakes from Aircraft with High Aspect Ratio Wings

Active and passive vortex wake mitigation using control surfaces

“…This dependency cannot be shown due to the coupling between circulation and span ratio in the chosen model set-up. Following Stuff [26], slightly stronger flap vortices are needed for lower span ratios. Furthermore, due to the criteria used in this work to characterise the wake vortex alleviation, the limiting circulation ratio Γ 2 /Γ 4 > −0.29 differs from the values (Γ 2 /Γ 4 > −0.2) given by Stuff [26].…”

“…24 the limit of the circulation ratio is shown. Stuff [26] shows that this limit is in fact a function of the span ratio. This dependency cannot be shown due to the coupling between circulation and span ratio in the chosen model set-up.…”
