Hydrodynamic Analysis for the Morphing Median Fins of Tuna during Yaw Motions

Figure 12

The ratios and lift increment of the anal and second dorsal fins in the two morphing states with the yaw angular velocity of  rad/s, 1 rad/s, and 1.5 rad/s, respectively: (a) the ratio of the anal fin; (b) the ratio of the second dorsal fin; (c) the lift increment of the anal and second dorsal fin.
