Fixed-wake analysis of the Darrieus rotor

Technical Report ·
OSTI ID:6465337
Development and validation of a Darrieus wind turbine aerodynamic performance prediction model is described. Using a fixed-wake approach, the model combines some of the more desirable features of vortex/lifting line and conservation of momentum/streamtube approaches. The model thus accounts for up- and downwind differences that are predicted by vortex approaches while retaining the short computer run times found with streamtube models. The model treats the effects of stall, curved blades, blade pitch, and blade attachment location. Results agree with those obtained with Sandia National Laboratories' 17-m-diameter Darrieus VAWT.
