Actuator disk theory. The simplest model of a horizontal axis wind turbine(HAWT) is one in which the turbine rotor is replaced by an actuator disk which removes energy from the wind. As the wind strikes the actuator disk on the upwind side, the pressure rises there, and the wind is deflected away from the disk, causing a large wake downstream of the disk. Actuator disk theory relates the pressure drop across the disk to the change in wake size and the energy which can be extracted from the wind.  2, record 2, English, - actuator%20disk%20theory

Pitch Regulation. Once the rated wind speed has been reached, a WT [wind turbine] will be unable to make use of all of the wind energy incident on the rotor plane and must shed some. A pitch-regulated WT [wind turbine] will do this [namely] by pitching the blades to increase the angle of attack to cause sections of the blade to stall (in pitch-to-stall machines).  4, record 4, English, - fixed%2Dpitch%20wind%20turbine

Success of vortex theories in the performance analysis of horizontal axis wind turbines depends greatly upon accurate specification of the geometry of the vortex wake... An earlier wake model of helicopter rotors is extended for wind turbine applications, the fast free wake method(FFW). The FFW was accomplished by partitioning the flow field downstream of the rotor into three regions :(1) the near wake, modeled as a series of straight vortex lines;(2) the intermediate wake, modeled as a number of vortex rings; and(3) the far wake, taken to be a semi-infinite cylindrical wake.  3, record 5, English, - fast%20free%20wake%20method
