Can computational models accurately simulate the complex flow fields around wind turbines? This paper presents an aerodynamical model for studying three-dimensional flow fields about wind turbine rotors. The developed algorithm combines a Navier-Stokes solver with an actuator line technique, distributing the loading along lines representing blade forces. The model's power production is found to be in good agreement with measurements. The computations provide detailed information about wind turbine wakes, including distributions of interference factors and vortex structures. The model serves to analyze and verify the basic assumptions employed in simpler engineering models. This research provides a valuable tool for understanding and predicting the behavior of wind turbine wakes, contributing to the advancement of wind energy technology. The developed model enables more accurate analysis and optimization of wind turbine performance, facilitating the design of more efficient and reliable renewable energy systems.
