Abstract

Numerical calculations of the sound field are performed for 1MW class horizontal axis wind turbine rotor. The blade element momentum theory was adopted to get the aerodynamic data such as sectional lift, drag, and effective angle of attack on the specified blade section. Thickness and loading noise are obtained by using the Farassat's formula 1 A. Fukano's approach was also adopted to calculate the unsteady aerodynamic random noise due to the Karman vortex generation at the trailing edge of the wind turbine blade. From the noise prediction for the 1MW class horizontal axis wind turbine, the frequency band of the discrete noise lies in the infrasound region, and that of the random noise lies in the audible band region.
