Abstract
In an experiment conducted with the 130-kilowatt NASA
Mod-0 wind turbine, vortex generators were installed on the
low- pressure surfaces of the outboard 30% of the turbine
blades. The subsequent improvement in airfoil section
performance resulted in marked increases in power output.
Between tip speed ratios of approximately 3.0 and 6.5,
power coefficients were increased by 11.4 to 30.61.
When these results were compared to data obtained in a
vortex generator experiment performed with a Boeing Mod-2
wind turbine, similar trends were seen.
Finally, using 3-dimensional wind tunnel data obtained
from a full-scale test of a Mod-0 blade section in the
NASA-Langley 30x60-foot wind tunnel, the wind turbine
performance prediction code WINDlS was used to predict the
effect of vortex generators on a Mod-0 wind turbine having
blades similar (but not identical) to those with which the
Mod-0 was operated during the rotating tests. Qualitative
differences are ascribed to actual differences between the
wind tunnel model and the operating turbine blades, and to
the possible presence of spanwise flow on- the blades at
moderate tip speed ratios.
