Unsteady Aerodynamic Design and Performance Analysis of Different Multi MW ClassHorizontal Axis Wind Turbine Blade Profiles on SST-K-ω Model

Nowadays, modern wind turbines are using bladeswith multi airfoils at different sections. In thisinvestigation the performance for the S۸xx, FFAand AH airfoil series are surveyed. SST-K-ω modelwith different wind speed at large scale profileapplied to simulation of horizontal axis windturbines (HAWT). The aerodynamic simulationwas accomplished using Computational FluidDynamic (CFD) method based on the finite volumemethod. The governing equations apply in thissimulation are the Unsteady Reynolds AveragedNavies Stocks (URANS) equations. Theaerodynamic coefficients of lift and drag werecalculated at different angles of attack and differentwind speeds. The results are validated by Epplercode, Xfoil and experimental data of the U.SNational Renewable Energy Laboratory (NREL).The comparisons show that the CFD code used inthis study can exactly predict the best wind turbinegeometry for aerodynamic loads.
