Three-dimensional isosurface plots of negative values of velocity component u (streamwise velocity) 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. Results for our ‘S’-shaped model at 0° and 180° are identical, and so the latter is not shown. Direction of ambient flow in each panel is from top left to bottom right. Scale bar: 10 cm.
