Overcoming critical design challenges of wind turbines
This project addresses four specific aeroelastic design challenges of wind turbines through development, demonstration and implementation of new tools and models. The project is carried out in close collaboration between the research partners and key players in the wind energy indsutry to ensure utilization of state-of-the-art experimental facilities and effective implementation of the results.
The objective of the project is to develop, demonstrate and implement new models, tools and experimental techniques to reduce the uncertainty associated with design of wind turbines, enhance specific characteristics, and ultimately reduce their cost. In collaboration with the two industry partners, Siemens Wind Power and LM Wind Power, specific aeroelastic design challenges of high priority in current wind turbine research and development will be addressed. Utilizing state-of-the-art industry-driven experimental facilities and applying high fidelity research methods, new tools and models will be developed and implemented that enable the industry partners to meet these challenges. The four work packages are:
- Design and validation of new thick arifoils;
- Identification of 2D/3D thick airfoil data;
- Identification of the standstill problem using aeroelastic 3D computational fluid dynamics;
- Identification of the importance of elastic couplings in the aeroelastic behaviour of wind turbine blades.
The objective of the project was to develop, demonstrate and implement new models, tools and experimental techniques to reduce the uncertainty associated with design of wind turbines ultimately reducing their cost. Four areas of research were addressed: Design and validation of new thick aerofoils, where measurement uncertainty was reduced through detailed characterization of the LM wind tunnel, demonstrated on a new thick aerofoil; extraction of 3D aerofoil data for thick high lift aerofoils and
implementation of a new CFD model for vortex generators; Identification of key mechanisms governing blade vibration at standstill though state-of-the art fluid-structure interaction simulations; Identification of the importance of elastic couplings for enhanced load alleviation characteristics of blades where new models were implemented to model these effects correctly.
