The present work aims to numerically reproduce turbulent
atmospheric fields within a CFD context in order to investigate the performance
and loading of a wind farm. High fidelity aeroelastic LES simulations with
turbulent inflow are performed for a subset of a wind farm consisting of three IEA
15 MW wind turbines aligned in a row and spaced 5 rotor diameters apart.
Simulations are performed for two wind directions, one axial inflow and one with
30 degrees yaw. High–fidelity in–house tools are employed, CFD code MaPFlow
coupled with the elastic solver hGAST. The Actuator Line Method is used to
simulate the wind turbine rotors, while a new approach is used to introduce
turbulent inflow. The results provide insights on the way turbulence structures
interact with rotor disks and on the loading of downwind turbines due to rotor
wake interaction.
