“…Initial research in this area is concerned with the influence of turbulence on an airfoil of wind turbine blade. This work is the extension of the work done by Tenguria et al (2010) in which he redesigned a blade for VESTAS V82-1.65 MW HAWT based on optimal rotor theory and carried out structural analysis.…”

Blade is very essential part of HAWT (horizontal axis wind turbine). Forces for Lift and drag on the blade has an important role in the wind turbine performance. The main purpose of this work is to perform CFD analysis of a blade and airfoil of wind turbine using k- SST model. In this present study NACA 63 4 -221 airfoil profile is taken for the modeling and then analysis of the blade. The lift and drag forces are calculated for the blade at different AOA (angle of attack). For present work the blade length is taken 38.98 meter, which is a redesigned blade for VESTAS V82-1.65MW horizontal axis wind turbine blade. Results obtained from simulation are compared with the experimental work found in literature.

“…By understanding how fatigue is progressing for the different components within a turbine and for the specific turbines within a farm, the possibility of letting the turbines run the expected lifetime or even consider lifetime extension is higher . Sensors on strategic parts can assist in providing data for calculating remaining loads and fatigue either through finite element method or cycle count (during the whole lifetime of the turbine) . Keeping a turbine in prolonged lifetime operation equals increased revenue, but it also has higher operation and maintenance costs and a greater risk of structural failures.…”

Wind power is one of the fastest growing renewable energy sources. The wind turbines have an expected design lifetime in the range of 20 to 25 years after which decommissioning is expected. The trend in the wind turbine industry is that the turbines increase in size—especially when considering offshore wind turbines in the 7 to 8 MW size range. Life cycle assessments show that the materials used for manufacturing the turbines accounts for 70 to 80% of the environmental impact, so ensuring optimal recycling at the end‐of‐service‐life is of economic and environmental interest and in line with the principles of transitioning towards a circular economy. The decommissioning and recycling process is analysed in this paper, with special considerations given to the environmental aspects of a theoretical 100% recyclability scenario. This includes cradle‐to‐gate life‐cycle inventory analysis of the materials, embedded energy, and CO2‐equivalent emissions. The findings show that established recycling methods are present for most of the materials and that recycling of a 60 MW wind park at end‐of‐service‐life provides environmental benefits as well as lowering the natural resource use and securing resources for use in the future. The saved energy is estimated to approximately 81 TJ. The reduction in emissions related to the recycling of wind turbine material totals approximately 7351 ton CO2.

“…Lee et al [7] numerically investigated the load reduction of large wind turbine blades using active aerodynamic load control devices, namely trailing edge flaps. Tenguria et al [8] studied the design and analysis of large horizontal axis wind turbine, and NACA airfoils were taken for the blade from root to tip.…”

In this chapter, four main topics in composite blades of wind turbines including design, stress analysis, aeroelasticity, and fatigue are studied. For static analysis, finite element method (FEM) is applied and the critical zone is extracted. Moreover, geometry, layup, and loading of the turbine blades made of laminated composites are calculated and evaluated. Then, according to the stress analysis, critical layer is specified and safety factor is studied based on Tsai-Wu failure criterion. Aeroelasticity is the main source of instability in structures that are subjected to aerodynamic forces. One of the major reasons of instability is the coupling of bending and torsional vibration of flexible bodies, which is known as flutter and considered in this study. Numerical and analytical methods are applied for considering the flutter phenomenon of the blades. For numerical method, the FEM and Joint Aviation Requirements (JAR-23) standard and for analytical method, two-degree freedom flutter and Lagrange's equations are utilized. Also, lifetime prediction of a horizontal axis wind turbine composite blade is investigated. Accumulated fatigue damage modeling is employed as a damage estimation rule based on generalized material property degradation.
