This paper presents an aeroelastic formulation based on the Finite Element Method (FEM) to predict the performance of an isolated horizontal axis wind turbine. Hamilton’s principle is applied to derive the equations of blade(s) aeroelasticity, based on a nonlinear beam model coupled with Beddoes-Leishman unsteady sectional aerodynamics. A devoted fifteen-degrees of freedom finite element, able to accurately model the kinematics and elastic behavior of rotating blades, is introduced and the spatial discretization of the aeroelastic equations is carried-out yielding a set of coupled nonlinear ordinary differential equations that are then solved by a time-marching algorithm. The proposed formulation may be enhanced to face the analysis of advanced blade shapes, including the presence of the tower, and represents the first step of an ongoing activity on wind energy based on a FEM approach. Due to similarities between wind turbine and helicopter rotor blades aeroelasticity, validation results firstly concern with the aeroelastic response of a helicopter rotor in hovering.

Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. The optimization framework integrates DAFoam as the computational fluid dynamics (CFD) solver, TACS as the finite element method (FEM) solver, Mphys for fluid–structure coupling, and SNOPT as the optimizer within the OpenMDAO framework. The design variables in this optimization process are the blade shape and panel thickness. The remainder of this paper starts with a literature review on the aerostructural optimization of wind turbine blades in Section 2, followed by the methodology on the aerodynamic optimization, structural optimization, and fluid–structural coupling processes of the aerostructural optimization in Section 3, and the main findings are presented and discussed in Section 4.

# A comprehensive review of numerical simulation techniques for wind turbines: from computational fluid dynamics and finite element analysis to advanced turbulence modeling. This review critically examines state-of-the-art numerical methodologies for the simulation of wind turbines, offering a rigorous exploration of their theoretical foundations, practical implementations, and comparative performance. The core of the study delves into advanced computational techniques encompassing computational fluid dynamics (CFD), finite element analysis (FEA), and fully coupled CFD-FEA frameworks used to resolve aerodynamic, structural, and fluid–structure interaction phenomena with high fidelity. The paper systematically analyzes turbulence modeling strategies, from industry-standard Reynolds-averaged Navier–Stokes (RANS) models to high-resolution large eddy simulation (LES) and hybrid detached eddy simulation (DES) approaches, evaluating their capabilities in capturing unsteady flow structures, vortex dynamics, and wake interactions. Through a comparative synthesis of these methods, the paper provides deep insights into their trade-offs in terms of computational cost, physical realism, and practical applicability, ultimately guiding the selection and optimization of simulation strategies for advanced wind energy system design and performance evaluation. ### A comparative study of RANS-based turbulence models for an upscale wind turbine blade.
