<p>A vortex generator device (70) for mounting on a wind turbine blade (10) is disclosed. The device comprises a base (71) having, when mounted on an exterior of the wind turbine blade (10), an inner side (72) for attaching on a surface, such as the exterior of the wind turbine blade (10), and an outer side (73) facing away from the exterior of the wind turbine blade (10). The vortex generator device (70) is provided with a vane vortex generator pair comprising a first vane (79) and a second vane (80) protruding from the outer side (73) of the base (71). The base (71) is trapezium-shaped with a first end (75) and second end (76) as well as a first side (77) and a second side (78), wherein the first side (77) is longer than the second side (78), and wherein the first vane (79) is arranged at and substantially parallel to the first end (75) of the base (71), and the second vane (80) is arranged at and substantially parallel to the second end (76) of the base (71).</p> |
