Acoustic measurements will be performed at various degrees of wake using several measuring techniques. The results will be compared with aerodynamic measurements to enhance knowledge of wind turbine
In this project, by means of computer simulations, flow conditions of wing tips were investigated for a number of wing designs for wind turbines. Various numeric design methodologies were developed
For the first time ever, this project integrated three design areas in a simulation: electrical design and
optimisation of wind turbines (generator and gearbox), aerodynamic design (material and
This project developed methods and tools for modelling various ruptured wind turine blades and for analysing the residual strength of the blades if they crack. This provides a foundation for assessing
This project involved the first two phases in establishing a knowledge centre for wind turbine components. In the first phase, the knowledge centre was officially established, and it was decided that
The project aims to provide the necessary basis for deciding to establish a knowledge centre promoting Danish innovation in the field of wind turbine components. The purpose of the tesst centre will
The project endeavoured to calculate electricity generation costs in modern onshore wind turbines. At average operating costs of DKK 0.08/0.10/kWh, production costs per kWh can be calculated at DKK 0
To extend the life of gear oil - not least for use in offshore wind turbiens - the project aims to investigate whether nano-filtration using CJC filters (cellulose fibres) with zeolites eliminates the
The project constituted a phase of the strategic partnership between Risø DTU and the wind turbine industry on developing an aeroelastic design complex. The project worked with the following issues
Aalborg University and Risø/DTU have developed a model to estimate responses and structural reliability of wind turbines under normal operation. Various Monte Carlo simulation algorithms were tested
Today, wind turbine control systems are designed separately from its structural, aerodynamic qualities, but to achieve cheaper, more reliable wind turbines, the design phases need to be united into
The project studied sediment bed conditions, scour/erosion, and quick-sand-like conditions that may occur due to the effects caused by wave and current action. Illustration from laboratory experiment
On a hot windy summer day, with beautiful clouds in the sky, the air is full of turbulence, like a hot pot of boiling water. In these unsteady surroundings a bird of prey is hovering, completely still
This project has validated the use of the noise prediction model Nord2000 for more detailed noise prediction from wind farms compared to conventional methods like the ISO 9613-2.
