Vortex generators aligned with trailing edge features on wind turbine blade

A wind turbine blade comprising:

• a trailing edge with a waveform profile;
• a first spanwise series of vortex generators on a suction side of the blade, wherein each vortex generator of the first spanwise series is aligned chordwise with a common first phase of the waveform profile;
• a second spanwise series of vortex generators, wherein each vortex generator of the second spanwise series is aligned chordwise with a common second phase of the waveform profile, wherein the waveform profile of the trailing edge is formed by a series of chordwise suction side troughs and an opposed nested series of chordwise pressure side ridges;
• and
• a plurality of first and second pressure side vortex generators on a pressure side of the blade, each first pressure side vortex generator aligned chordwise with the common first phase of the waveform profile, each second pressure side vortex generator aligned chordwise with the common second phase of the waveform profile, and each pressure side vortex generator designed to create a vortical flow that crosses the trailing edge at an angle of less than 20 degrees.
