Abstract
A method for determining an arrangement position of a vortex generator on a wind turbine blade includes: determining, for a first region of a mounting range of the vortex generator in a blade spanwise direction, an arrangement position of the vortex generator to be an angular position offset by a predetermined angle toward a trailing edge of the wind turbine blade with reference to an inflow angle of wind to the wind turbine blade; and determining, for a second region closer to a blade tip, the arrangement position of the vortex generator to be a position between a separation position of a flow on a surface of the wind turbine blade under a rated wind speed condition and a transition position of the flow on the surface of the wind turbine blade under a variable speed operation condition of a wind turbine including the wind turbine blade.
