Figure 5. Velocity profiles over the body surface of the sailfish.

Figure 5

Profiles of the mean streamwise velocity (left) and rms streamwise velocity fluctuations (right) at the anterior A, middle and posterior B parts of the sailfish: ○, X/TL  = 0.164 (37 cm; ReX  = 4.93×105); △, 0.200 (45 cm; ReX  = 6.00×105); □, 0.240 (54 cm; ReX  = 7.20×105); •, 0.373 (84 cm; ReX  = 1.12×106); ⋄, 0.507 (114 cm; ReX  = 1.52×106); ▪, 0.640 (144 cm; ReX  = 1.92×106); ▽, 0.773 (174 cm; ReX  = 2.32×106). –, turbulent boundary layer profile (1/7th power law) [45]. Here, X is the streamwise distance from the tip of bill, Y is the wall-normal distance from the body surface and θ is the momentum thickness (Table 2). The velocities are measured along the centerline of side surface of the sailfish at ReTL  = 3.0×106. Shown at the top are the measurement locations in the streamwise direction.
