Abstract: Rotor blade assemblies for wind turbines are provided. The rotor blade assembly includes a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge each extending between a tip and a root. The rotor blade further defines a span and a chord. The rotor blade assembly further includes at least one vortex generator configured on at least one of the suction side or the pressure side of the rotor blade, the at least one vortex generator having an aspect ratio between approximately 4 and approximately 10. In another embodiments, the rotor blade assembly further includes at least one vortex generator configured on at least one of the suction side or the pressure side of the rotor blade, the at least one vortex generator having a length between approximately 4% and approximately 20% of a local chord.

Abstract: Rotor blade assemblies for wind turbines are provided. In one embodiment, a rotor blade assembly includes a rotor blade, and a plurality of vortex generators configured on at least one of a suction side or a pressure side and disposed within an inboard area of the rotor blade. The plurality of vortex generators include a row of vortex generators extending in a generally span-wise direction, the row comprising a first portion of vortex generators and a second portion of vortex generators, the second portion of vortex generators spaced apart from the first portion of vortex generators in the span-wise direction. Each first portion vortex generator is disposed at a first chord-wise location, and each second portion vortex generator is disposed at a second chord-wise location different from the first chord-wise location.
