“…In fact, even though incremental improvements in the power output have continuously been sought through the aerodynamic optimization of rotor blade design [5,6], it has been definitively accepted that major gains in rated power can only be achieved by increasing the swept area of the rotor [7]. Hence, a massive rise in the dimension of high-scale wind turbines has been registered during the last 30 years, up to well over 100 m diameters [3,8,9].…”

“…Therefore, the moments of inertia in the local axes of each segment can be transferred to the axes which are parallel to the elastic axes of the blade cross-section by using the transform formula: where, β is the angle between the local axes of each segment and the elastic axes of the blade cross-section. The moments of inertia in Equations (14) and (15) can be transferred to elastic center of the blade cross-section by using the parallel axis theory:…”

“…The results indicated that the airfoils achieved a high power coefficient and were insensitive to surface roughness. Seyed Mehdi Mortazavi [14] presented a multi-objective genetic algorithm with objective functions of minimum energy waste and maximum efficiency. The results show that using the second law approach along with the Pareto optimality concept leads to a set of precise solutions.…”

The currently geometric and aerodynamic characteristics for wind turbine airfoils with the medium thickness are studied to pursue maximum aerodynamic performance, while the interaction between blade stiffness and aerodynamic performance is neglected. Combining the airfoil functional integration theory and the mathematical model of the blade cross-section stiffness matrix, an integrated design method of aerodynamic performance and structural stiffness characteristics for the medium thickness airfoils is presented. The aerodynamic and structural comparison of the optimized WQ-A300 airfoil, WQ-B300 airfoil, and the classic DU97-W-300 airfoil were analyzed. The results show that the aerodynamic performance of the WQ-A300 and WQ-B300 airfoils are better than that of the DU97-W-300 airfoil. Though the aerodynamic performance of the WQ-B300 airfoil is slightly reduced compared to the WQ-A300 airfoil, its blade cross-sectional stiffness properties are improved as the flapwise and edgewise stiffness are increased by 6.2% and 8.4%, respectively. This study verifies the feasibility for the novel design method. Moreover, it also provides a good design idea for the wind turbine airfoils and blade structural properties with medium or large thickness.

“…It was found that the shear rate in a flow produce some changes in the lift coefficient but the angle of attack does not have a significant effect. Mortazavi et al (2014) worked to achieve a Pareto optimal set of solutions by using a multi-objective genetic algorithm for geometrical characteristics of airfoil sections for 10-meter blades of a horizontal axis wind turbine. A 2D incompressible unsteady CFD solver and the second law analysis were used to evaluate the performance of the airfoil sections during the process of energy conversion.…”

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.
