Prediction and Reduction of Noice from Wind Turbines

The project concerns the modelling of aerodynamically generated sound from wind turbines with the alm of predicting and reducing noice emission 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 noice generating sources. The next is to develop a design tool that includes a semi-empirical noice model in existing optimizing tools for wind turbines. Finally based on the two other tasks, a realistic model for atmospheric propagation of noice 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 noice model.
