Isues of the innovation renewable energy sources as a substitute for fossil energy is growing rapidly. Among the renewable energy sources is a stream of water. Now that it has been widely studied to improve the performance of water turbine. Where to obtain an efficient turbine blade, needed the hydrodynamic characteristics data of water turbine blades depends on the chosen / designed foil. This final project analyzing the hydrodynamic characteristics of NACA 0021 hydrofoil with numerical calculations using Computational Fluid Dynamics (CFD). The focus of this numerical studies is to investigate the effect of changing angle of attack and velocity variations into hydrofoil which modeled in two dimensions. Comparison of simulation data with experimental data shows the ability of CFD to simulate the fluid flow along the surface of the hydrofoil. The simulation also can provide information about the hydrodynamic characteristics as lift and drag coefficients. Where the maximum lift coefficient was obtained at angle of attack α = 45o at a speed of 4 m/s at 1,1363. While the maximum drag coefficient was obtained at angle of attack 90o. Keywords: Lift Coefficient, Drag Coefficient, hydrofoil, NACA 0021, angle of attack 0o-180o.
