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 1, English, - actuator%20disk%20theory

Numerical modelling focused on the continued development of a prescribed wake vortex model for HAWT [horizontal axis wind turbine] performance prediction. This model represents the turbine blades as lifting lines from which emanate filaments of trailed vorticity. In yawed flow, additional filaments of shed vorticity are produced and the unsteady loading on the blades is represented by a semi-empirical unsteady aerofoil model. 2, record 4, English, - prescribed%20wake%20model
