Short summary
This study, a part of the Blade Extensions for Silent Turbines project, explores how turbulent airflows affect the noise generated by large onshore wind turbines. Using advanced simulations and an analytical model, we show that as turbine blades grow larger and thicker, turbulence behaves differently near the blade, changing how noise scales. These insights help to design quieter, more efficient next-generation wind turbines.
