Figure Lengend Snippet: Linear correspondence between starting vortex circulation magnitude and VIA jet magnitudes for the hydromedusa Eutonina indicans . ( A ) Total, or combined, circulation of starting vortices compared to the mean of maximum VIA vector speeds adjoining both vortices and ( B ) change in total circulation and mean maximum vector speeds. All data represent 2D measurements derived from particle image velocimetry (PIV) images for the pulsation cycles depicted in and .
Article Snippet: Velocities of particles illuminated in the sheet were determined using digital particle image velocimetry (DPIV) software (Lavision Inc., Ypsilanti, MI, USA) that analyzed sequential video frames using a cross-correlation algorithm.
