Abstract
Disclosed is a wind turbine blade and a method for retrofitting a wind turbine blade, the wind turbine blade extending in a longitudinal direction along a pitch axis and having a tip end and a root end as well as a blade length, the wind turbine blade further comprising a profiled contour including a pressure side and a suction side, as well as a leading edge and a trailing edge with a chord having a chord length extending there between, the profiled contour, when being impacted by an incident airflow generating a lift, wherein the suction side of the wind turbine blade is provided with a plurality of vortex generators positioned along a mounting line having a proximal end point nearest the root end and a distal end point nearest the tip end, wherein the mounting line is a concave line seen from the trailing edge of the wind turbine blade.
