Abstract:In this master thesis a small scale wind turbine was designed to be implemented in the University of Twente aeroacoustic wind tunnel. The wind turbine should serve as an educational instrument for students taking the course Wind Energy offered by the university. The wind turbine should also serve as a testbed for aerodynamic and aeroacoustic research into wind turbines. In this report, the design of the nacelle and tower is described. The nacelle consists of a drive train with similar components to the large scale wind turbines and has integrated sensors that allow for the measurement of the most important parameters governing the wind turbine performance. These being: the thrust force, rotor axle torque and rotational velocity. Because of the placement of the sensors inside the wind turbine nacelle, the wind turbine was aptly named the Twente Instrumented Nacelle (TwIN) wind turbine. The wind turbine was tested using the wind tunnel at the university and was found to function properly, although the sensor accuracies can be improved in further research. Finally, the wind tunnel experimental research was compared to the predicted behaviour of the rotor which was estimated using the Blade Element Momentum theory.
