Estimating the Power of Wind Turbines, Revisited

摘要

For a wind turbine, there are various design considerations including the design of the blades and the control of the turbine. Figure 1 shows the hub and blades of a wind turbine. A turbine blade's cross-section is an aerofoil. The turbine rotates because of the lift force on the blades. The wind speed at the turbine is v. Where the cross-section has been taken, the blade moves perpendicular to the direction of the wind with speed Ωr, where Ω is the rotational speed of the turbine.
