As an illustration of the potential of the method, terrain and generator box influence on the behavior of the turbine are simulated in a uniform freestream wind. The generator box of the turbine is modelled as a solid cube and viscous no-slip boundary conditions are prescribed on the generator box and the ground plane. The influence of the terrain on the flowfield of the turbine is considered for two hypothetical, two-dimensional ridgelines. Computed turbine performance, such as the power coefficient and the normal force coefficient, are compared with results from Sandia field tests and a theoretical method based on streamtube momentum balance for a stand alone turbine. Quantitative differences in the performance of the Sandia 17-m turbine with and without the hypothetical terrains are discussed. Qualitative behavior of the flowfield under the influence of the ground plane is also presented with the help of velocity vector plots and path lines.
