Design and Simulation of Vertical Axis Wind Turbine with Naca 0021 Rotor Angle

Much human energy needs are obtained from fossil fuels. This is decreasing day by day. So that the utilization of natural such as solar energy, water and wind being developed. Wind we can find, so it very easy to use using a turbine driving force. The vertical axis type easier apply in places where potential not too large. research was conducted means simulation Qblade v0.963 software comparing influence generated several numbers rotor blades. From process, known blades with 4 turbines capable producing greatest power, which 75 Watts at low TSR. manufacturing process does require large costs, but still has be built rigid solidly.
