In this report, Large Eddy Simulation (LES) approach with the Kunz mass transfer model within the two-phase flow solver of the OpenFOAM package, interPhaseChangeFoam, are employed to simulate the dynamic and unsteady behavior of cavitation. Compared to the straight leading edge hydrofoil, it provided a thorough report of time-averaged and instantaneous fluid dynamic characteristics of the cavitating flow around the sinusoidal leading edge hydrofoil, i.e., pressure, velocity, and vorticity fields, as well as lift and drag coefficient, turbulent kinetic energy, and boundary layer characteristics are described.
