| Résumé : | This thesis proposes a hybrid methodology for the coupled aerodynamic and aeroacoustic analysis of wind turbines. The principal contribution lies in the integration, within a unified computational framework, of actuator-based aerodynamic models with the Ffowcs Williams–Hawkings (FW-H) acoustic analogy, which serves as an intermediate formulation bridging the unsteady aerodynamic field and the radiated acoustic field. Far-field sound propagation is subsequently modelled using the Linearized Euler Equations (LEE). The methodology is first validated against an isolated wind turbine, then extended to co-axially aligned configurations, for which an optimal inter-turbine separation of six rotor diameters is established as a compromise between power efficiency and acoustic emissions. A multi-objective optimization framework for wind farm layout design is further developed, demonstrating the significant influence of turbine arrangement on both aerodynamic performance and noise characteristics. |
