Fig. 9. Vorticity plots at half-wing length at various times during one cycle.
Solid and broken lines indicate positive and negative vorticity, respectively.
The magnitude of the non-dimensional vorticity at the outer contour is 2 and
the contour interval is 3. A-D, downstroke; E-H, upstroke. Reynolds number
Re=20, stroke amplitude 
=150°, midstroke angle of attack
m=40° and non-dimensional duration of wing rotation
r=1.87 (mean angular velocity of rotation 
=0.93);
symmetrical rotation.
