Sustainability has become one of the most significant considerations in everyday work, including energy production. The fast-growing trend wind around world increased demand for efficient and optimized airfoils, which paved way harvesting systems. present manuscript proposes an aerodynamically design well-known existing NREL S809 airfoil performance enhancement blade turbines. An integrated cod...

With increased interest in renewable energy, the power capacity of wind turbines is constantly increasing, which leads to rotor sizes. ever larger diameters, complex and non-linear fluid-structure interaction (FSI) effects on turbine aerodynamic performances become significant, can be fully studied using hi-fidelity 2-way FSI simulation. In this study, a two-way model developed implemented Open...

In this study, airfoil shape optimization of a wind turbine blade is performed using the ANSYS Fluent Adjoint Solver. The aim process to increase output power, and objective function maximize lift drag ratio (Cl/CD ). This study applied NREL phase VI turbine, therefore, S809 used as reference profile. First, for validation numerical model, steady-state simulations are carried out at various ang...

Abstract In the present work authors developed a methodology based on an inverse BEM method, to easily extrapolate 3D aerodynamic coefficients from HAWT CFD simulation results. Specifically, since method was solution of discrete number blade radial sections, model implemented in Ansys Fluent such way split surface one blades certain sections already at CAD level. Therefore, normal and tangentia...

The work presented in this article aims to the calculation of the aerodynamic characteristics of the NREL phase II rotor that is a horizontal axis downwind wind turbine rotor and which is assumed to stand isolated in the space. The Reynolds averaged Navier-Stokes equations combined with the Spalart-Allmaras turbulence model that describes the three dimensional steady state flow about the wind t...

This paper describes the structural testing of two NedWind 25, 12-m blades at the National Renewable Energy Laboratory (NREL). The tests were conducted under the Standards, Measurement and Testing (SMT) Program in conjunction with tests conducted by four European laboratories to develop a common database of blade testing methods. All of the laboratories tested duplicate copies of blades taken f...

Over recent years, considerable attention has been devoted to the optimization of energy production in wind farms, where yaw angles can play a significant role. In order quantify and maximize such potential power, simulation wakes is vital. present study, an actuator line model code was implemented OpenFOAM flow solver. A tip treatment applied involve effect induced by pressure equalization fro...
