Dye-injection flow visualizations of a slender ogive cylinder in low-speed water-tunnel testing (side-view). Flow is from left to right and Reynolds number based on cylinder diameter and flow velocity=3500. AOA is angle of attack which is defined as the angle the cylinder makes with the horizon. | |
