What is Dynamic Stall Vortex in Airfoil Pitching about?

This study investigates the physics of the dynamic stall vortex (DSV) during the pitching oscillation of a NACA 0012 airfoil, utilizing high-accuracy unsteady pressure measurements. The research examines the motion characteristics, propagation velocity, and frequency characteristics of the DSV, revealing that the mean angle of attack (AoA) affects DSV strength linearly, while amplitude impacts it nonlinearly. The findings enhance the understanding of DSV behavior, which is crucial for predicting dynamic sta
