What is it about?
The reverse flow phenomenon is a critical aspect of helicopter aerodynamics during forward flight. In this study, we present a computational validation for a static NACA 0012 airfoil under reverse flow conditions. The simulations investigate the influence of a transition turbulence model on predicting aerodynamic forces.

Why is it important?
This study presents a comprehensive computational framework for modeling airfoils in reverse flow. It highlights the importance of using a transition modeling approach over fully turbulent simulations for accurate aerodynamic predictions.
Perspectives
Working on this study was a rewarding experience, both for its technical challenges and the collaboration it fostered with colleagues who share a deep interest in helicopter aerodynamics. Publishing this research not only advanced our understanding of reverse flow phenomena but also sparked engaging discussions with rotorcraft engineers and researchers, further motivating my exploration of unconventional aerodynamic conditions.
