Aeroacoustic wind tunnel tests

, 2020
The global demand for renewable energy sources has led to an increase in development and installation of wind turbines. However, noise regulations on wind turbines near populated areas can restrict the installation of new wind turbines and limit the potential energy production. The main noise from wind turbines is aerodynamic and arises from turbulence
