Vertical axis Darrieus water turbine, very suitable for use in river flow in the utilization of the kinetic energy. Darrieus H-type hydrokinetic turbines are electromechanical energy converters that generate electricity from harness kinetic energy of flowing water to generate electricity. The design water speed is 1.5m/s , tip speed ratio 4 and the final power output is designed to be 100W through water turbine. The designed water turbine has 3 blades. Electricity is generated by using Darrieus H-type hydrokinetic turbine. Blade design is made of fiber and the chord length of 0.0742m. The diameter and the height of turbine are 0.354m and 0.531m with two circular end plates. Steel shaft has 7.85mm in diameter. Hydrofoil NACA 0018 is chosen based on max CL/CD ratio at angle of attack 10’. The design hydrokinetic turbine can be used for pico hydro generation in rural communities non-connected to electricity. This research can provide to generate the electricity Darrieus hydrokinetic Turbine with low cost and local materials.
