Aerodynamics for wind turbines

Wind turbines are machines driven by aerodynamics. Their loads, performance, and also the majority of the noise they produce depend directly on the aerodynamics of the rotor blades themselves. Developments which improve the aerodynamics of wind turbines are therefore an ongoing requirement, and we utilize Computational Fluid Dynamics (CFD) to bring about these improvements.

At Fraunhofer IWES, one of our main focuses is on the enhancement of numerical methods for better prediction of wind turbine aerodynamics and, to this end, we employ the open-source CFD code OpenFOAM. We work intensively in the following fields, where we can offer you detailed investigations and solutions to your specific problems.

 

Meshing and CFD Simulations of Wind Turbines

Advanced CFD simulations of complete wind turbines can assist you during the design phase and can be used to analyze specific flow behavior. Our automated mesh generation tools offer the possibility of performing efficient CFD simulations.

 

Airfoil Simulations and Optimization

Airfoil polars can be generated by CFD with steady-state or unsteady eddy-resolving methods. In addition, add-ons like vortex generators can be included and the airfoils can be optimized for certain conditions.

 

Improvements to Engineering Models

The Blade Element Momentum (BEM) theory is the basis for wind turbine design. However, improvements to the models used can lower your costs.

Load calculation and System Dynamics

The department of load calculation and system dynamics conducts research in the field of aero-hydro-servo-elastic simulations of wind turbines and boasts expertise in the load analysis of wind turbines.

Software Developments and Tutorials

For some tools the software may need to be extended. We can offer you this development specifically tailored to your individual requirements. In addition, please take a look at our tutorials.

OpenFOAM Training and SOWE

Open-source codes are not always easy to use, but we can teach you how to simulate with OpenFOAM. Moreover, if you wish to engage in greater depth with the community, you are welcome to attend the Symposium on OpenFOAM in Wind Energy.
