Aero-acoustic noise of wind turbines. Noise prediction models

摘要

Semi-empirical and CAA (Computational AeroAcoustics) noise prediction techniques are the subject of this expert meeting. The meeting presents and discusses models and methods. The meeting may provide answers to the following questions: What Noise sources are the most important. How are the sources best modeled. What needs to be done to do better predictions. Does it boil down to correct prediction of the unsteady aerodynamics around the rotor. Or is the difficult part to convert the aerodynamics into acoustics. (LN)
