A COMPARATIVE FLOW ANALYSIS OF NACA 6409 AND NACA 4412 AEROFOIL

Abstract

In this work, flow analysis of two aerofoils (NACA 6409 and NACA 4412) was investigated. Drag force, lift force as well as the overall pressure distribution over the aerofoils were also analysed. By changing the angle of attack, variation in different properties has been observed. The outcome of this investigation was shown and computed by using ANSYS workbench 14.5. The pressure distributions as well as coefficient of lift to coefficient of drag ratio of these two aerofoils were visualized and compared. From this result, we compared the better aerofoil between these two aerofoils. The whole analysis is solely based on the principle of finite element method and computational fluid dynamics (CFD). Finally, by comparing different properties i.e drag and lift coefficients, pressure distribution over the aerofoils, it was found that NACA 4412 aerofoil is more efficient for practical applications than NACA 6409 aerofoil.
