The NACA 0015 exhibits a "trailing edge stall," where the flow separation begins at the rear and moves forward as the AoA increases. 5. Conclusion

The comparison between experimental and numerical data for the NACA 0015 shows high correlation, though CFD models often slightly under-predict drag at high angles of attack. This profile remains a robust choice for applications requiring predictable symmetric performance.

Technical Report: Aerodynamic Characteristics of the NACA 0015 Airfoil 1. Abstract

The NACA 0015 is a standard benchmark in aerodynamics due to its symmetry and well-documented performance. It is frequently used in the design of aircraft vertical stabilizers, helicopter rotors, and wind turbines. The primary objective of this analysis is to validate numerical data against historical experimental results to ensure accuracy in design applications. 3. Methodology 3.1 Geometry and Profile
