In this study, for aerodynamic analysis the vertical axis of Darius H type of hydrofoil micro water turbine, three hydrofoil NACA0015, NACA0018 and NACA0021 were selected and modeled using the Bezier equation of hydrofoil using its original model. Then, using the HOPMBL coding method, which was solved by the boundary element method, the NACA0015 hydrofoil pressure distribution coefficient was better than the other two hydrofoils numbers in different Reynolds numbers, and in another method, the maximum lift to drag coefficient using Q-Blade NACA0015 hydrofoil software The drip lift is higher on the Reynolds 53670 than on any other hydrofoil, at 5.9degree angle of 24.3, which is why the NACA0015 was chosen. Then, to analyze the hydrofoil of the fluent software, it used the KW-SST model to obtain the lift coefficient, drag coefficient and the pressure distribution coefficient in terms of length, and compared it with the data obtained from the Q-Blade software. Next, the water micro turbine with NACA0015 hydrofoil with chord length, blade height and rotor radius of 6.4, 35 and 18.5 cm was designed in catia software and manufactured. Then, the hydro-turbine designed in Ansys Fluent software was simulated with Realizable k-e model and analyzed velocity and pressure static conditions.
