Wind tunnel measurements and predicted noise from a downwind rotor horizontal axis wind turbine
The potential of wind power to provide a fraction of US energy needs would be enhanced by a favorable environmental impact of wind turbines. One important factor in such an environmental impact is the aerodynamic noise generated by large wind turbines. This is especially true for a downwind rotor horizontal axis wind turbine. The flow field (wake) through which the rotor passes in a downwind horizontal axis configuration is quite complex. To delineate the noise sources resulting from a rotor interacting with the tower-wake requires a careful modelling of the phenomena experimentally and theoretically. This paper describes recent results obtained at MIT on the experimental and theoretical modelling of the aerodynamic noise generated by a downwind rotor horizontal axis wind turbine.
