Abstract. This paper considers the application of a scale-adaptive simulation (SAS) CFD formulation for the modeling of single and waked wind turbines in flows of different turbulence intensities. The SAS approach is compared to a large-eddy simulation (LES) formulation, as well as to experimental measurements performed in a boundary layer wind tunnel with scaled wind turbine models. The motivation for the use of SAS is its significantly reduced computational cost with respect to LES, made possible by the use of less dense grids. Results indicate that the two turbulence models yield in general results that are very similar, in terms of rotor-integral quantities and wake behavior. The matching is less satisfactory in very low turbulence inflows. Given that the computational cost is about one order of magnitude smaller, SAS is found to be an interesting alternative to LES for repetitive runs where one can sacrifice a bit of accuracy for a reduced computational burden.

Short summary
This paper describes a Scale Adaptive Simulation (SAS) approach for the numerical simulation of wind turbines and their wakes. The SAS formulation is found to be about one order of magnitude faster than a classical LES approach. The simulation models are compared to each other and with experimental measurements obtained with scaled wind turbines in a boundary layer wind tunnel.
