Abstract
nThis study delves into the aerodynamic effects and characteristics of surface-modified NACA 2416 airfoils, placing a greater emphasis on the aerodynamic efficiency of a two-dimensional surface-modified NACA 2416 airfoil under subsonic flow conditions at Re=80000 and various angles of attack (AOAs). The surface-modified airfoils were crafted using CATIA V5, and simulations were conducted in ANSYS Fluent for angles of attack ranging from 0° to 12°.The CFD results encompass a broad spectrum of surface modifications, including cuts of 20%, 40%, and 80% on the bottom surface. The analysis covers key aerodynamic characteristics such as the Coefficient of Lift, Coefficient of Drag, and Pressure Distribution. The airfoil featuring an 80% chord cut, positioned near the trailing edge, exhibits a gradual flow acceleration, leading to increased pressure on the lower surface and consequently, a maximum lift coefficient. Flow separation is identified within the range of 0° to 12° AOA for all three airfoils. Notably, airfoils with an 80% chord cut experience earlier stall compared to the other two airfoils.
