Abstract
This work will present a collection of numerical methods, which are combined into a single framework for aerodynamic and fluid-structure interaction (FSI) modeling and simulation of wind turbines. The numerical formulation of the Navier-Stokes equations of incompressible flows is validated using experimental data for a full-scale wind turbine. The structural modeling of composite blades is based on the Kirchhoff-Love thin shell theory discretized with isogeometric analysis (IGA). The coupled FSI formulation accommodates non-matching fluid-structure interface discretizations. The challenges of fluid-structural coupling and the handling of the computational mesh in the presence of large rotational motions will be discussed, and the FSI computations of a 5MW offshore baseline wind turbine rotor will be shown.
