Abstract

It is proved that a tip vane can improve the wind turbine´s efficiency by the test and CFD. In this paper, the performance of horizontal axis wind turbine and horizontal axis wind turbine with a tip vane by CFD were simulated. After comparing the velocity distribution around wind turbine blade with the tip vane-V(8.8×8) and without the tip vane and combining the velocity vectors figure of the certain location, the change of the velocity distribution around wind turbine blade and the weakening of the vortex around blade tip with the tip vane can be seen. These can further display the power augmentation theory of the wind turbine by the tip vane.
