Optimal and Simulation of HAWT Blade S809

The object of this study to analysis of airfoil S809 blade with optimized condition and prepare 3D modeling when using Blade Element-momentum theory and Computational Fluid Dynamic theory.The Standard Airfoil Data using to optimized the blade parameter like twisting angle and chord length.The aerodynamic study and pressure contour study on blade with CFD and FEM analysis, but the systematic term of Euler's Equation, forces magnitude and direction and the velocity attack to the blade is to be a 4 degree of angle of attack.A blade acts much like an airplane wing, when the wind flow through blade and the pressure generation factor work to lifting the the blade.The Pressure gradient in upper and lower surface of blade is different which is cause the aerodynamic structure of blade.The simulation of wind turbine with large eddy and the equation use like Reynold-Average, Navier-Stokes and Direct Numerical Simulation.
