Moeller produces 1.25-inch, first-stage turbopump blades all the way up to 28-inch power generation blades. Indeed, at a wind speed of 10 m/s, the power output of the wind turbine is improved by about 38% compared to that of the original turbine. Moeller provides high-pressure compressor, high-pressure turbine (HPT), and low-pressure turbine (LPT) blade solutions. The downwind side of the blade has a large curve, while the upwind side is relatively flat. These latter results indicate that when the blades are designed with the optimized airfoils, the wind turbine aerodynamic performances increase significantly. This shape, known as an airfoil, is like an uneven teardrop. Thereafter, the optimized airfoils are used for the design of the NREL Phase VI blade and the aerodynamic performances of this new wind turbine are assessed using the open-source code QBlade. The results show that (i) the lift to drag ratios of the optimized airfoils are significantly improved compared to the baseline S809 airfoil, (ii) this improvement is sensitive to the Reynolds number, and (iii) the C l/ C D ratios are also improved for another angle of attack values. Next, computations are performed for the fluid flow around the optimized airfoils at angles of attack AOA= 6.1° ranging from 0° to 20°. Then, the optimization is performed with the airfoil set at a fixed angle of attack,, considering three Reynolds numbers, Re =3 10 5,4.8 10 5 and 10 6. First, for the validation of the applied numerical model, steady-state simulations are carried out for the S809 airfoil at various angles of attack. This study is applied to the NREL phase VI wind turbine, therefore, the S809 airfoil is used as a reference profile. ![]() The aim of this optimization process is to increase the wind turbine output power, and the objective function is to maximize the airfoil lift to drag ratio ( C l/ C D ). properties of many spar and porous mesh airfoil materials and their. In this study, airfoil shape optimization of a wind turbine blade is performed using the ANSYS Fluent Adjoint Solver. The fabrication techniques and experience gained on the larger.
