On the rotor lifting line wake model
WebRecent extension of the rotor lifting line model to the design of horizontal-axis turbines uncovered an inconsistency between the mathematical equations representing the lifting … WebAbstract. To simulate transient wind turbine wake interaction problems using limited wind turbine data, two new variants of the actuator line technique are proposed in which the rotor blade forces are computed locally using generic load data. The proposed models, which are extensions of the actuator disk force models proposed by Navarro Diaz et al. (2024a) …
