The turbulent flow around a wing in the atmospheric boundary layer is simulated. For initialising the turbulent wind field a synthetic turbulence generator is used. The turbulence generator generates a 3D turbulent field which matches important statistics from measurement data. In the results of the simulation an influence of the grid and turbulence mode on the resolved turbulent flow was observed. In general there is a decrease of resolved turbulent kinetic energy in the smaller scales when the turbulence leaves the Cartesian grid and enters the unstructured grid around the wing. In the analysis of the spectra of the aerodynamic forces it could be seen that only the largest scales of the turbulence have a significant effect on the aerodynamics of the wing. The results are preliminary, however, since the simulation is not yet finished and the analysis is not complete yet.
