title = "Predicting the cavitation phenomena over the hydrofoil: CFD validation",
abstract = "This study aims to numerically predict the cavitation phenomena over the NACA 66-012 hydrofoil and relate the cavitation which represented with the amount of vapor that generated over the hydrofoil to the lift and drag forces through its coefficients. The simulation selected with three-dimensional turbulent flow and implicit unsteady models. Four Different Angels of Attak (AoA) (0,6,9,12 degrees) were simulated using a Large Eddy Simulation (LES) method with Wall-Adapting Local Eddy (WALE) Sub-grid scale model to generate cavitation over the NACA 66-012 hydrofoil with high upstream flow velocity. The hydrofoil was tested in a square water tunnel with water enters the tunnel at (12.2 m/s) velocity for (0 and 6 degrees) and at (9.144 m/s) for (9 and 12 degrees). Using an earlier experimental data, it was found that the CFD results for the lift and drag forces acting on the hydrofoil follow the trend of that data and validate the CFD work. A unique number Averaged Vapor Volume Fraction (VVF) can be identified the cavitation amount over the hydrofoil and created an inverse correlation with the cavitation number (σ) at the same angle of attack.",
