Aerodynamic Analysis of NACA 65-2012 Airfoils at Different Attack Angles with Computational Fluid Dynamics (CFD) Method

Abstract

Airfoil is a form designed to create a force and is in fact a form of cutting a section of a wing. Airfoil Features in addition to Aircraft wings are of great importance in engineering and scientific applications in airplanes and ships, helicopters, compressors, turbines, fans, pumps, wind tunnels, hydraulic channels, mills and other industries. Reducing the post-time rate in all parameters of the bird's performance, such as maximum speed, rapid acceleration, shortening the required take-off band, high maneuverability, and effective reduction of fuel consumption. Therefore, an assessment of how airflow forces change in different flows from the point of view Industrial is of particular importance. Given the fact that the Transient range of audio in aerodynamic analyzes is of particular importance, this study deals with the numerical analysis of an Airfoil from the NACA Series 6 to the 65-2012 specifications. Fluent software is used for analysis. The results indicate that the airfoil has a better performance in certain conditions of flight and in certain intervals of the attack angle. Since the results of the numerical solution in comparison with the experimental results have been very well adapted and are well able to estimate different flow parameters at different angles of attack, numerical results can be used in the related industries to reduce costs.
