Prediction and reduction of noise from wind turbines

The project is divided into three main tasks. The first is to develop an advanced computer model that solves the basic aero-acoustic equations in order to compute the noise generating sources. The next is to develop a design tool that includes a semi-empirical noise model in existing optimizing tools for wind turbines. Finally based on the two other tasks, a realistic model for atmospheric propagation of noise generated by wind turbines in complex terrain will be develloped. A main ingredient in the project is the use of advanced Computational Fluid Dynamics (CFD), both as a part of the advanced computer model and to derive empirical input to the semi-empirical noise model
