摘要： A wind turbine blade with a flow guiding device attached to a profiled contour on a pressure side of the blade is described. The flow guiding device extends along at least a longitudinal part of a transition region of the blade and is arranged so as to generate a separation of airflow along at least a central longitudinal portion of the flow guiding device from the pressure side of the blade at a point between the flow guiding device and a trailing edge of the blade, when the blade is impacted by an incident airflow. The flow guiding device is arranged at a relative chordal position, seen from the leading edge of the blade, lying in an interval between 40% and 92%. The relative height of the flow guiding device is at least 10% of a maximum thickness of the profiled contour.
