Optimal tip speed ratio

WebAug 2, 2014 · Their optimum operating conditions (maximum power coefficient) depend on rotor solidity and tip speed ratio [ 22 ]. For a VAWT rotor solidity depends on the number of blades, airfoil chord and rotor radius. Tip speed ratio is a function of angular velocity, undisturbed wind speed and rotor radius. WebThe reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies. The aerodynamic efficiency, or coefficient of power, for a fixed blade pitch angle is obtained by operating the wind turbine at the optimal tip-speed ratio as shown in the following graph.
