Cross-sectional plot for three target models. Top row: Case UW; bottom row: Case NS, where black lines correspond to the free surface, i.e. the intersection between the iso-surface (volume fraction = 0.5) and cross-sectional plane; 1st column: magnitude of the vorticity at U = 1.5 m/s; 2nd column: magnitude of the vorticity at U = 4.0 m/s; 3rd column: iso-surface of the swirling strength W = 0.01 s −1 at U = 4.0 m/s, and the iso-surface is colored by the magnitude of the velocity. The CAD models are created in Rhinoceros17.
