DESIGN OPTIMIZATION AND ANALYSIS OF AN AEROFOIL

Mechanical Engineering

Aerofoil profile is very important in any aerodynamic system. While the shape of the aerofoil changes, its aerodynamic characteristics also change. Our study focuses primarily on changes in aerodynamic factors such as coefficient of lift (Cl) and coefficient of drag (Cd) due to minor variations in the coordinates of an aerofoil and angle of attack . We used standard symmetric aerofoil naca 0015 as reference because of its great performance in low wind speed and eight new aerofoil shapes introduced by changing chord thickness distance from leading edge of standard naca 0015 aerofoil without changing its maximum thickness in percent of chord . The aerodynamic airfoils of wind turbine blades have a crucial influence on aerodynamic efficiency of wind turbines. CFD (Computational Fluid Dynamics) analysis was carried out using ANSYS FLUENT 19.2 at various angles of attack from 0° to 12. Flow changes have been recorded for these aerofoil shapes and the results are arrived at for finding the best aerofoil that can be advisable to be used in wind turbines
