Abstract
A vortex generator device for a wind turbine blade, and a wind turbine blade is disclosed, the vortex generator device comprising a base with an inner side and an outer side, and a first fin protruding from the outer side and extending along a first fin axis, wherein the vortex generator device is a single-fin vortex generator device, and the base has a first edge part and a second edge part, the first edge part and the second edge part forming a primary angle in the range from 5 degrees to 60 degrees.
Claims18
A vortex generator device for a wind turbine blade, the vortex generator device comprising:
- a base with an inner side and an outer side;
- a first fin protruding from the outer side and extending along a first fin axis, wherein the vortex generator device is a single-fin vortex generator device, and the base has a first edge part and a second edge part, the first edge part and the second edge part being straight, the first edge part and the second edge part forming a primary angle in the range from 5 degrees to 60 degrees, and the base having a first leading corner edge part between the first edge part and the second edge part, the first leading corner edge part being curved;
- and
- an adhesive material on the inner side of the base, the adhesive material comprising an adhesive tape,
- wherein the adhesive material has a structure for reducing air bubble formation between the base and the wind turbine blade.
A vortex generator device for a wind turbine blade, the vortex generator device comprising:
- a base with an inner side and an outer side;
- a first fin protruding from the outer side and extending along a first fin axis, the first fin having a first primary chord end and a first secondary chord end, the first fin having a first primary fin height at the first primary chord end and a first secondary fin height at the first secondary chord end, the first primary fin height being smaller than the first secondary fin height;
- and
- a second fin protruding from the outer side and extending along a second fin axis, the second fin having a second primary chord end and a second secondary chord end with a primary distance between the first primary chord end of the first fin and the second primary chord end of the second fin, and a secondary distance between the first secondary chord end of the first fin and the second secondary chord end of the second fin,
- wherein the primary distance is larger than the secondary distance.
