Abstract

Disclosed is a wind turbine blade (10) and a method for retrofitting a wind turbine blade (10), the wind turbine blade (10) extending in a longitudinal direction (r) along a pitch axis and having a tip end (16) and a root end (14) as well as a blade length (L), the wind turbine blade (10 further comprising a profiled contour including a pressure side (52) and a suction side (54), as well as a leading edge (56) and a trailing edge (58) with a chord (60) having a chord length (C) extending there between, the profiled contour, when being impacted by an incident airflow generating a lift, wherein the suction side (54) of the wind turbine blade is provided with a plurality of vortex generators positioned along a mounting line (36) having a proximal end point (37A) nearest the root end and a distal end point (37B) nearest the tip end, wherein the mounting line (36) is a concave line seen from the trailing edge (58) of the wind turbine blade (10).
