3D flow structure behind a flapping wing captured by volumetric particle image velocimetry (3D-PIV). Thge wing generates a strong downward jet at the end of the downstroke associated with a vortex ring. This is illustrated by the streamlines colored by the magnitude of the velocity. The translucent gray surfaces show the isosurface of the vorticity. For the experiments, Re = 7500 and St = 0.35.
