Vortvid

Typical spatial-temporal evolution of the streamwise iso-vorticity contours of a tip vortex generated by a NACA 0015 wing oscillated with α(t) = 0o + 6osinωt at κ = 0.1, x/c = 2 and Re = 1.7 x 105.

Solid line denotes the instantaneous location of the wing trailing edge.

Deep Stall

Typical spatial-temporal evolution of the phase-averaged streamwise iso-vorticity contours of a tip vortex generated by a NACA 0015 wing oscillated with α(t) = 18o + 6osinωt at κ = 0.1 and x/c = 2.
