Abstract [en]

In the field of wind energy, structures containing flexible and flow adaptive elements are continuously developed. In this context, Fluid Structure Interaction (FSI) simulations provide an accurate support for the estimation of loads and the forecast of performances, by calculating interactions between the fluid and the solid domains.The present article investigates the structure and the numerical behavior of the FSI solver icoFsiFoam provided by the software OpenFoam, through the modeling of an existing cantilever anemometer. The aim of the work is hereby to isolate important parameters relative to icoFsiFoam and optimize them for the studied case.Various analyses demonstrate the sensitivity of the solver to parameters corresponding to the solid domain. In particular, the solid mesh and tolerance levels of the solid solver have a great impact on the simulation results. Further observations also show that the form of the discretized solid governing equation has an influence on the transient FSI simulation.
