Modèle hybride de surface active pour l'analyse du comportement aérodynamique des rotors éoliens à pales rigides ou déformables

Abstract : This work presents the exploration and modeling of flow past wind turbine rotor. The aim is to propose an actuator surface hybrid model to simulate rapidly the flow and also be coupled with structure solver for fluid structure interaction. Besides numerical simulation, the PIV and hot wire explorations are also carried out. These explorations of flow around the wind turbine and rotating blades airfoil have provided the data necessary to calculate 3D airfoil aerodynamic performance while in rotation. The results of these measurements are also used to validate the proposed model. The new actuator surface model is developed to model the flow around wind turbine rotor. To implement the proposed model, Navier-Stokes solver is used. Specific software is created and integrated into the solver to determine the forces applied on the blade surfaces after each iteration. The aerodynamic performance obtained by this hybrid model is compared with experimental data of NREL Phase VI obtained in wind tunnel at NASA Ames. Whereas, the velocity field around the blade airfoil and flow past the rotor are compared with experimental data obtained in this research work in the wind tunnel of Arts et Metiers ParisTech. Further research shows that this model is well suited for the study of flexible wind turbines blades, where it is needed to take into account the fluid-structure interaction. To validate the proposed method for the flexible blades, a study is also conducted for the case of the NREL Phase VI wind turbine. The simulation results are finally compared with experimental data which show the feasibility and effectiveness of the proposed model and the coupling method.
