Abstract
Many experiments were done to study hydrofoil's characteristics near the free surface. But, Reynolds number has been transition zone in examination cases of hydrofoil. Reynolds number and turbulence effect are important for foil characteristics. For the reason, a NACA4412 hydrofoil section was computed by CFD to research effect of Reynolds number near the free surface. Used CFD solver is SURF developed by NMRI. First, computational and experimental results were compared to discuss turbulence effect in experimental cases. After that, Computational results were compared with other Reynolds number (A) to discuss turbulence effect in turbulent flow range.
