Abstract

Wind turbine noise has become an important issue when developing onshore
wind farms as turbines have scale up rapidly in the latest decades. The interest of this project is focused on the characterization and modelling of noise as a source based on the specific physics from wind turbines. A dedicated evaluation of wind turbine noise measurements is carried out in order to know more about the behaviour of it in front different operational conditions. Such study assists to understand trends that can be introduced to improve existing semi-analytical or empirical aeroacoustic models, typically used, in wind turbine noise predictions. The result, enhanced aeroacoustic models with an overall uncertainty reduced when compared to measurements. Therefore, these reliable models can be used for future predictions when scoping new rotors or for performance analysis, i.e. development of low-noise strategies.
