内容記述
The prediction of the aerodynamic noise generated from a small wind turbine is achieved based on the blade element method. The aerodynamic noise which is generated due to the wake vortex is recognized as a dominant factor of the noise. First of all, the accuracy of the prediction equation of the analytical model is validated in the wind tunnel experiment using the NACA00 series blades. The aerodynamic performance and noise of an actual wind turbine are measured in another suction type wind tunnel. Finally, the narrowband noise generated from the wind turbine was predicted by the wake characteristics deduced from the blade element method.
