For articles published under an open access Creative Common CC BY license, any part of the article may be reused without permission provided that the original article is clearly cited. 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.

The structural properties of the tower (such as stiffness and natural frequency) can significantly affect the performance of the wind turbine, and the cost of the tower is a considerable portion of the overall wind turbine cost. Therefore, an optimal structural design of the tower, which has a minimum cost and meets all design criteria (such as stiffness and strength requirements), is crucial to ensure efficient, safe and economic design of the whole wind turbine system. In this work, a structural optimisation model for wind turbine towers has been developed based on a combined parametric FEA (finite element analysis) and GA (genetic algorithm) model. After validation, the model has been applied to the structural optimisation of a 5MW wind turbine tower. The results demonstrate that the proposed structural optimisation model is capable of accurately and effectively achieving an optimal structural design of wind turbine towers, which significantly improves the efficiency of structural optimisation of wind turbine towers.

* 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. Wind turbine blade, CFD, Structural analysis, Aero-structural optimization. Optimization of wind turbine blade designs using computational fluid dynamics and structural analysis: a review.

3. Journal of Energy and Power Technology. *Journal of Energy and Power Technology* focuses on all aspects of energy and power. *Journal of Energy and Power Technology (JEPT)* is an international peer-reviewed **Open Access** journal published quarterly online by LIDSEN Publishing Inc. This periodical is dedicated to providing a unique, peer-reviewed, multi-disciplinary platform for researchers, scientists and engineers in academia, research institutions, government agencies and industry. The journal is also of interest to technology developers, planners, policy makers and technical, economic and policy advisers to present their research results and findings. This research demonstrates implementation of Taguchi Design of Experiment (DoE) in conjunction with Signal-to-noise ratio (S/N) to optimise both structural design parameters and material cost of a 90 m tower of a standard 5 MW WT tower subjected to adverse wind conditions. Model 1, made of steel grade S275, 95 mm wall thickness and 0.45 top-to-bottom diameter ratio, is found optimal.
