Forced motion simulations of vortex-induced vibrations of wind turbine blades – A study of sensitivities

Autor: Grinderslev, Christian, Houtin-Mongrolle, Felix, Nørmark Sørensen, Niels, Raimund Pirrung, Georg, Jacobs, Pim, Ahmed, Aqeel, Duboc, Bastien

Vortex-induced vibrations on wind turbine blades are a complex phenomenon not predictable by standard engineering models. For this reason, higher fidelity computational fluid dynamics (CFD) methods are needed. However, the term CFD covers a broad ran

A parked wind turbine can be subjected to large yaw angles, which causes vortex shedding. Under some particular inflow conditions, the interaction between the shed vorticity and the blade structure could lead to Vortex-Induced Vibrations (VIV). VIV a

In this study, simulation results of two different computational fluid dynamics codes, Nalu-Wind and EllipSys3D, are presented for a wind turbine rotor in complex yawed and sheared inflow. The results are compared to measurements from the DanAero exp
