Wind turbines represent a rapidly growing source of renewable energy but current predictive tools have been shown to lack accuracy in predicting the power output of wind turbines. Additionally, wind farm performance must be properly predicted to develop accurate annual energy estimates. An aeroelastic, aeroacoustic, discrete vortex code called SmartRotor was used to predict the performance of the benchmark National Renewable Energy Laboratory (NREL) wind turbine experiment. The code properly predicted the NREL wind turbine performance in normal and yawed flow conditions and has demonstrated the capability of simulating the wake interference effects present in wind farms. The grid-free characterization of the wake behind the turbine and the rapid simulation time compared with grid-based computational fluid dynamics solvers highlights the relevance of the code for industrial applications.
