Hydrodynamic Characterization of the Polyodon spathula Rostrum Using CFD

Figure 4

The geometry and mesh of the square cylinder validation case (Lyn et al. [15, 16]). Based on the rectangular side length 𝐷 (where 𝐷=0.04 m), a domain of size 21.5𝐷×14𝐷×4𝐷 was formed. Two different, nonuniform, hexagonal mesh densities were created; the first was composed of 130×120×20 cells (𝑦⁺=100), and the second was composed of 180×180×40 cells (𝑦⁺=30).
