Two-dimensional plots (vertical cross-sections) of turbulent kinetic energy magnitude (k) at an inlet velocity of 0.1 m/s for three Pectinifrons models

Different Pectinifrons morphotypes (i.e., ‘U’- and ‘S’-shaped) are arranged in rows, while models in different orientations to current (i.e., 0°, 90°, and 180°) are arranged in columns. Within each panel, the uppermost plot shows a vertical cross-section toward the margin of the model (gentle ‘U’-shaped model at 0° and 180°, y = 23 cm; gentle ‘U’-shaped model at 90°, y = 7 cm; steep ‘U’-shaped model at 0° and 180°, y = 18 cm; steep ‘U’-shaped model at 90°, y = 7 cm; ‘S’-shaped model at 0°, y = 22; ‘S’-shaped at 90°, y = 5 cm), while the lower plot shows a vertical cross-section at the approximate center of the model (y = 0 cm). Direction of ambient flow in each panel is from left to right. Scale bar: 10 cm. See also Figures S7 and S8.
