Dataset of the experimental investigation of the effects of wishbone vortex generators on the NACA 4412 airfoil at low Reynolds numbers.

This dataset contains wind tunnel measurements and XFOIL numerical predictions for a NACA 4412 airfoil equipped with wishbone-type vortex generators (VGs) at chord-based Reynolds numbers between 30,000 and 100,000. Lift and drag coefficients (Cl, Cd) are reported as a function of the geometric angle of attack (AoA) for the clean baseline airfoil and for multiple VG configurations differing in chordwise location (15% c and 20.82% c), spanwise spacing, and VG size (large / small wishbone). XFOIL predictions at three transition-strip settings are included for comparison.
