We approach up-to-date research topics in wind energy with the help of computational fluid dynamics (CFD) simulations, statistical data analysis, and stochastic methods. The set-up of the CWP team is highly interdisciplinary and aims at bringing together the different disciplines.

The research topics in this team cover a broad range of scales. In numerical simulations, we cover large-scale phenomena taking place in the atmospheric boundary layer including meteorological aspects down to the deformation of single rotor blades under the influence of wind. The simulation and modeling of synthetic turbulent wind fields plays a major role here. In the context of our research, a lot of data is generated, which we analyse. 

We model and simulate synthetic turbulent wind fields which exhibit the characteristics of real wind such as intermittency. Intermittent wind displays a higher probability of extreme events. In the next step, these wind fields are fed into Large Eddy Simulations.

Furthermore, we investigate the interaction of elastic wind turbine rotors with the incoming wind. This interaction is determined by the characteristics of the rotor and the incoming wind. In Fluid Structure Interaction Simulations, a Computational Fluid Dynamics routine is coupled to a structural solver which allows an investigation of the aeroelastic effects at the rotor. Turbulent inflow conditions pose a challenge here.
