Abstract

This study is concerned with the modelling of low-frequency noise from wind turbines and the comparison of model predictions with experimental data. The model consists of a wind turbine aeroelastic code that can account for the effects of atmospheric turbulence combined with a noise generation model. The latter is based on the well-known Farassat 1A formulation that can compute the noise generated by aerodynamic loadings on the blades in the far-field. The results of the overall model are compared with noise measurements conducted on two wind turbines. The input parameters of the turbulence model are tuned to reflect the actual atmospheric conditions during the measurement periods. The comparisons show a relative good agreement between the predicted and measured low frequency noise levels.
