Sample interview questions: Can you discuss your knowledge of wind turbine aerodynamic noise prediction models?
Sample answer:
Knowledge of Wind Turbine Aerodynamic Noise Prediction Models
As a Wind Energy Engineer, I am well-versed in various aerodynamic noise prediction models used to assess the acoustic impact of wind turbines. Key models include:
-
International Electrotechnical Commission (IEC) 61400-11: A standard method widely employed for predicting overall sound power levels and tonal noise from wind turbines. It considers noise generated by rotor blades, mechanical components, and electrical systems.
-
Noise Emission Contours for Rotor Blades (NECR): A semi-empirical model that predicts noise levels from individual rotor blades. It accounts for blade shape, rotational speed, and wind speed.
-
Atmospheric Absorption and Scattering (AA&S): A model that predicts how atmospheric conditions (e.g., temperature, humidity, turbulence) affect sound propagation from wind turbines.
