description abstractThe impact of Gurney flaplike strips, of different geometric configurations and heights, on the aerodynamic characteristics and the tip vortices generated by a reverse delta wing (RDW) was investigated via forcebalance measurement and particle image velocimetry (PIV). The addition of sideedge strips (SESs) caused a leftward shift of the lift curve, resembling a conventional trailingedge flap. The large lift increment overwhelmed the corresponding drag increase, thereby leading to an improved lifttodrag ratio compared to the baseline wing. The lift and drag coefficients were also found to increase with the strip height. The SESequipped wing also produced a strengthened vortex compared to its baseline wing counterpart. The leadingedge strips (LESs) were, however, found to persistently produce a greatly diffused vortex flow as well as a smallthanbaselinewing lift in the prestall خ± regime. The downward LES delivered a delayed stall and an increased maximum lift coefficient compared to the baseline wing. The LESs provide a potential wingtip vortex control alternative, while the SESs can enhance the aerodynamic performance of the RDW.
