The flow past a 95 kW Tellus rotor equipped with LM8·2 blades is computed using computational fluid dynamics for a standard tip and a swept tip. The difference in the near-tip flow for the two tips for various tip speed ratios is examined and 3D airfoil data are extracted. The radial distribution of the averaged axial induction factor and the normal and tangential loads are compared with those of a standard blade element momentum code using 2D calibrated airfoil data for a wind speed of 9 m s−1, where the agreement in computed power is good. Further, a comparison with a new tip loss model proposed by Shen et al. has been performed for the same wind speed. Copyright © 2004 John Wiley & Sons, Ltd.
