Analysis and modeling of unsteady aerodynamics with application to wind turbine blade vibration at standstill conditions
Since the introduction of computational models for the dynamic aeroelastic response of wind turbines, numerous dynamic issues have been investigated to assist in understanding and overcoming problems as well as help designing reliable turbines. In some cases specific problems have necessitated evolution of new or improved sub-models in the aeroelastic computational tools, such as for instance the so called dynamic stall models that models the dynamic aerodynamic response from the onset of separation until the flow over the airfoil is fully separated.

The hypothesis of this project is that a new wind turbine concept developed specifically for offshore application has potentials for better cost efficiency than existing offshore technology. Based on this hypothesis the project has the overall objective to explore the technologies needed for development of a new and simple floating offshore concept with a vertical axis rotor and a floating and rotating foundation. Additionally, the objective is to develop calculation and design tools for development and evaluation of very large wind turbines based on this concept.

Structural Blade Design and Testing 
With the explosive growth within wind energy, more research is needed in the area of structural design and testing of wind turbine blades. When the blade design is up-scaled without optimization, its weight increases cubically with respect to the performance. Therefore it is crucial to optimize the design of  future blade. The main focus is to try to understand why and where the blades fail and then improve the design accordingly. A combination of experimental and numerical studies is used to address the most critical failure mechanisms observed during full-scale tests and the corresponding.
