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

Figure 13

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