Aeroelasticity of Large Horizontal Axis Wind Turbines: Simulation Approaches and Modeling Challenges (Keynote)
Mohamed Sayed (University of Stuttgart), Thorsten Lutz (University of Stuttgart), Shahrokh Shayegan (Technical University of Munich), Roland Wüchner (Technical University of Munich)

Kurzfassung:
Currently, the wind turbine design trend is up-scaling which results in larger slender and flexible wind turbine blades. Therefore, as wind turbine blades become lighter and more flexible, aeroelastic instabilities must be of great concern. Most of the current aeroelasticity tools are based on simplified models of the aerodynamics and the structural dynamics. Therefore, the accuracy level of the engineering models compared to the high-fidelity models were investigated.

Transient aeroelastic simulations of wind turbines with composite blades.
Gilberto Santo (Ghent University), Mathijs Peeters (Ghent University), Wim Van Paepegem (Ghent University), Joris Degroote (Ghent University)

Kurzfassung:
A fluid-structure interaction model is employed to numerically investigate the interaction of wind flow and blade structures of a horizontal axis wind turbine. On the fluid side, the atmospheric boundary layer is included and sliding interfaces are adopted to handle the rotation of the rotor. On the structural side, a detailed model of each blade composite structure is used. The two models are coupled in a transient simulation where stresses, loads and deformations of the blades are monitored.

Aspects of FSI with aeroacoustics in turbulent flow
Thorsten Reimann (Technical University of Darmstadt), Awais Ali (Technical University of Darmstadt)

Kurzfassung:
In recent years, reliable resolved simulations of FSI problems containing turbulent flow have become more frequent, and thus opened the possibility to consider aeroacoustics in such setups as well. Noise generation in turbulence can then be considered in designs of flexible structures. In our FSI simulation environment, we incorporate an acoustic splitting approach to account for aeroacoustics in low Mach number flow. We discuss important problems and obstacles that emerge in such a scenario.

Official preCICE Adapters for Standard Open-Source Solvers
Benjamin Uekermann (Technical University of Munich), Hans-Joachim Bungartz (Technical University of Munich), Lucia Cheung Yau (Technical University of Munich), Gerasimos Chourdakis (Technical University of Munich), Alexander Rusch (Technical University of Munich)

Kurzfassung:
To deal with the increasing complexity of today's multiphysics applications, the reuse of existing simulation software often becomes a necessity. Coupling to open-source simulation codes, in particular, is a time-efficient way to tackle new applications. The open-source coupling library preCICE enables such coupling in a minimally-invasive way. In this contribution, we give an overview on ready-to-use preCICE adapters for standard open-source solvers, namely CalculiX, Code\_Aster, OpenFOAM, and SU2.
