A　5-MW　wind　turbine　has　been　modeled　and　analyzed　for　fluid-structure　interaction　and　aerodynamic　performance.　In　this　study,　a　full-scale　model　of　a　5-MW　wind　turbine　is　first　developed　based　on　a　computational　fluid　dynamics　(CFD)　approach,　in　which　the　unsteady,　noncompressible　Reynolds　Averaged　Navier–Stokes　(RANS)　method　is　used.　The　main　focus　of　the　study　is　to　analyze　the　tower　shadow　effect　on　the　aerodynamic　performance　of　the　wind　turbine　under　different　inlet　flow　conditions.　Subsequently,　the　finite　element　model　is　established　by　considering　fluid/structure　interactions　to　study　the　structural　stress,　displacement,　strain　distributions　and　flow　field　information　of　the　structure　under　the　uniform　wind　speed.　Finally,　the　fluid-structure　interaction　model　is　established　by　considering　turbulent　wind　and　the　tower　shadow　effect.　The　variation　rules　of　the　dynamic　response　of　the　one-way　and　two-way　fluid–structure　interaction　(FSI)　models　under　different　wind　speeds　are　analyzed,　and　the　numerical　calculation　results　are　compared　with　those　of　the　centralized　mass　model.　The　results　show　that　the　tower　shadow　effect　and　structural　deformation　are　the　main　factors　affecting　the　aerodynamic　load　fluctuation　of　the　wind　turbine,　which　in　turn　affects　the　aerodynamic　performance　and　structural　stability　of　the　blades.　The　structural　dynamic　response　of　the　coupled　model　shows　significant　similarity,　while　the　structural　displacement　response　of　the　former　exhibits　less　fluctuation　compared　with　the　conventional　centralized　mass　model.　The　one-way　fluid-structure　interaction　(FSI)　model　shows　a　higher　frequency　of　stress-strain　and　displacement　oscillations　on　the　blade　compared　with　the　two-way　FSI　model.　©　Chinese　Ocean　Engineering　Society　and　Springer-Verlag　GmbH　Germany,　part　of　Springer　Nature　2024.
