Abstract: Designs for conventional ducted wind turbines usually include a large inlet for more absorption of the airflow. However, the most efficient solution should be increasing the speed of wind. In this paper, a bucket-shape ducted wind turbine is proposed and studies show that a sucking effect can be produced according to the Bernoulli's principle, and this significantly increases the wind speed inside the duct and substantially enhances the efficiency of the wind turbine. Moreover, the geometry of the duct is optimized by the combination of an improved complex algorithm, an object-oriented optimizing program interface, and simulations by CFD software. According to the analyses, the optimal shape for the interior of the duct appears to be an unconventional nozzle, which extends the range of wind speed by 60%.
