* Optimization of wind turbine blade designs using computational fluid dynamics and structural analysis. **Paper Title:** Optimization of wind turbine blade designs using computational fluid dynamics and structural analysis: a review. **Corresponding Author:** Sudheer Choudari (sudheer.13031@gmail.com)/ India. Wind turbine blade optimization requires coordinated improvement of aerodynamic efficiency, structural reliability, fatigue life, manufacturability, and computational cost. This systematic literature review synthesizes studies on wind turbine blade design optimization using computational fluid dynamics and structural or aeroelastic analysis, with attention to design variables, modeling approaches, coupling strategies, optimization methods, validation practices, and limitations. The literature clustered into three streams: CFD-based aerodynamic shape optimization, especially airfoil, blade-tip, chord, twist, and sweep refinement; aeroelastic or multidisciplinary optimization balancing annual energy production with loads, fatigue, and control constraints; and structural or composite optimization addressing mass, stiffness, stress, deflection, buckling, laminate design, and manufacturability.

High-Fidelity Aeroelastic Analysis of a Wind Turbine Using a Nonlinear Frequency-Domain Solution Method

Aerodynamic and Vibration Characteristics of Iced Power Transmission Conductors in a Nonuniform Wind Field Based on Unsteady Theory. permission is required to reuse all or part of the article published by MDPI, including figures and tables. This paper investigates the aeroelastic behaviour of a full wind turbine model with realistic blade vibration amplitude (9% span) using a nonlinear frequency-domain solution method. The primary objective is to demonstrate the computational efficiency of this method for an aeroelastic analysis compared to resource-intensive time-domain approaches. The frequency-domain method was then validated against a conventional time-domain method, comparing aerodynamic damping and unsteady pressure distributions, with strong agreement observed. Results show a more complex unsteady pressure distribution at 324.5 RPM compared to 424.5 RPM, directly affecting aerodynamic damping. Aeroelastic analyses of a wind turbine with a relatively large amplitude blade structural oscillation at different rotational speeds are performed using the nonlinear frequency-domain method in this paper.

Three different CFD models of the turbine have been built with the following characteristics and abbreviations: – a one-third model with only one blade (OTM) and uni-form inflow conditions (Fig. 2b), – a full model of the turbine with a flat terrain with uni-form (FMU, Fig. 2c) or turbulent inflow conditions (FMT, Fig. 2d), – a full model of the turbine with a complex terrain (FMC) and turbulent inflow conditions (Fig. 2e). 3.2 Impact of the structural model and coupling algorithm In this section the use of beam and shell elements is com-pared for the turbulent inflow case in complex terrain (FMC) in Fig. 8.
