Analysis Of Flow Separation and Aerodynamic Behavior On Naca0012 and Naca0015 Airfoils

Öz

Low Reynolds Number airfoils are highly significant in micro aerial vehicles and small-size UAVs (Unmanned Aerial Vehicles), as well as in low-speed subsonic wind tunnel tests. At low Reynolds Numbers, viscous forces become more dominant, and the phenomena of this transition and the generation of Laminar Separation Bubbles are also very significant. The separation zone and width of the flow on the wing surface are the basic elements that directly shape the lift-drag coefficients and stall characteristics.Hence, an in-depth research on the flow behavior of symmetrical airfoils with various thickness values at Low Reynolds Numbers is a significant prerequisite for both aerodynamic design and validating numerical calculations. This study examines the flow separation behaviors and aerodynamic properties of NACA 0012 and NACA 0015 airfoils at low Reynolds numbers. The reverse and surface flow patterns are measured by oil flow visualization techniques, and the lift, drag, and moment forces are calculated by the XFLR5 software to understand the influence of flow separation on aerodynamic behavior. The experiments were conducted at Reynolds numbers of 50,000 and 75,000 for various angles of attack. The visualizations produced by the oil flow helped identify separation and reattachment zones, whereas the computational results were useful for understanding the stall angle and the generation of flow motion on the airfoil surface. The results clearly indicate the relationship between geometric thickness, the onset of flow separation, and aerodynamic efficiency, offering valuable data for low-Reynolds-number airfoil design and the validation of numerical models.
