To validate the accuracy of the prediction using a rotorcraft analysis code rFlow3D, NREL Phase VI wind turbine is selected as a test case. The rFlow3D code is a multi-disciplinary analysis tool of flow-structure coupling, with trim analysis and noise prediction in additions. It is found that even with a relative coarse resolution blade grid, the Euler solver can predict the performance of the wind turbine quite satisfactorily when the wind turbine is operated in attached flow conditions. With a Navier-Stokes solver, the prediction accuracy is improved with the refinement of the blade grid and the highest power can be predicted satisfactorily. For this case, the elastic deformation of the blade is minimal and its effect on aerodynamics is negligible.
