Abstract
A wind turbine blade has a vortex generator including a plurality of fins, and a height H(m) of each of the fins and a maximum chord length C (m) of the wind turbine blade satisfies 0.3×10≤H/C≤0.9×10. The height H of the fins may satisfy H≥0.1δ, provided that δis a boundary layer thickness at a rated tip speed ratio in a blade degradation state. A method for determining arrangement of a vortex generator on the wind turbine blade includes a pair of the fins arranged line-symmetrically with respect to a segment along a chordwise direction of the wind turbine blade.
