Analysis of Ducted Wind Turbine using Surface Vorticity Method abstract
In this study, surface vorticity method based on Biot-Savart law is implemented for analyzing the ducted horizontal axis wind turbine to calculate the aerodynamic performance. The present method requires considerable less computational time than CFD methods. Our goal is to present a method for considering the effects of the duct on the wind turbine enclosed in a duct with little numerical parameters. Indeed the present method requires only lift and drag coefficients as input parameters. This method can be utilized for any wind turbines, propellers, and also rotational bodies in the duct. To validate the current method, the DONQI URBAN WINDMILL is used as a test case. The results are in good agreement with experimental data. It indicates that this method has more accuracy for lower RPM and underpredicts the calculated power about 5-15% for higher RPM.
