Design & analysis of NACA 0012 airfoil with circular dent of 30 mm depth on upper surface

Abstract

This research paper presents the design and analysis of a NACA 0012 airfoil with a circular dent of 30 mm depth on its upper surface. The objective of this study is to investigate the effect of the dent on the airfoil's aerodynamic performance. The airfoil's geometry was modeled using a CAD software, and a CFD analysis was carried out using the ANSYS Fluent software to evaluate the airfoil's lift and drag coefficients. The results showed that the airfoil's performance was affected by the presence of the dent, with a decrease in lift and increase in drag. However, the airfoil's stall behavior was not significantly affected by the dent.
