Investigation of the MEXICO rotor aerodynamics in axial flow, including boundary layer transition effects

摘要

The current paper focuses on the numerical results obtained by ONERA on the three-bladed MEXICO wind turbine model within the framework of IEA Wind Task 29. Both low (lifting-line and unsteady free wake modeling) and high fidelity (CFD RANS) methods are used and analyzed, with special emphasis in CFD computations on the boundary layer transition. These results are compared to the wind tunnel database from the New Mexico experiments in terms of global performance of the wind turbine, but also spanwise loads, surface pressure distributions and 3D flowfield (thanks to PIV measurements).
