Abstract
A bladefor a horizontal-axis wind turbine rotor comprises a radially-outer, energy-extraction portionand a radially-inner, ventilation portion. The radially-inner ventilation portionis shaped to ventilate a central areaof a wake of the rotor during use such that it contains more kinetic energy compared to the wake from a conventional rotor design. The increased wind flow velocity at the centreof the wake generates additional shear stresses, with corresponding turbulence development, which gives rise to increased wake diffusion.
