Wind turbines have to comply with local noise regulations, which often limit the wind farm operating hours and the amount of energy that can be extracted from the atmosphere. Therefore, the aerodynamic noise generated by wind-turbine blades is one of the major research interests of the aeroacoustic research team. Combined usage of experimental techniques and high-fidelity numerical flow simulations is made to better understand trailing-edge noise generation mechanisms and develop ad-hoc noise reduction devices. Researches are conducted in collaboration and synergy with industry.
