Abstract

This paper presents a validation analysis of the full rotor CFD resolution approach for predicting the near wake dynamics of an experimental wind turbine model (namely MEXICO), with experimental PIV data serving as a benchmark. The study examines the axial and radial velocity components of the near wake at three distinct wind speeds: 10 m/s, 15 m/s, and 24 m/s, all recorded along axial and radial wake lines. The results reveal that the CFD simulations and experimental data align closely, with the CFD model accurately capturing the velocity deficits, wake recovery, and vortex interactions. The study demonstrates that the full rotor CFD resolution method can effectively predict complex flow dynamics behind wind turbine rotors, offering valuable insights into turbine aerodynamics and wind farm optimization. These findings highlight the potential of CFD-based methodologies with full rotor resolution to enhance wind turbine performance and design.
