Fig. 10. Flow patterns during the middle of the downstroke at t=13.79 s.
(A) Particle traces (streaklines). The particles were released on a plane
parallel to the wing and 3.9 cm below it, and velocity vectors are colored
according to the magnitude of absolute velocity (in cm s-1). (B)
Velocity vectors on the xy plane at z=20 cm. Velocity
vectors are colored according to the magnitude of absolute velocity (in cm
s-1) and are of constant length. (C) Pressure contours. Pressure is
non-dimensionalized with respect to the dynamic head.
