The purpose of the work described in this paper was to determine the aerodynamic loads and performance of a Darrieus wind turbine by including the expansion effects of the streamtubes through the rotor. The double-multiplestreamtube model with variable interference factors was used to estimate the induced velocities with a modified CARDAAV computer code. Comparison with measured data and predictions shows that the streamtube expansion effects are relatively significant at high tip-speed ratios, allowing a more realistic modeling of the upwind/downwind flow field asymmetries inherent in the Darrieus rotor.
