Unsteady aerodynamic damping characteristics of a pitching airfoil under surging motion: A Hilbert–dynamic mode decomposition analysis

Under coupled pitching and surging motions, the aerodynamic response of an airfoil undergoing dynamic stall exhibits strongly unsteady and transient characteristics and is prone to instability. However, existing methods still lack a quantitative framework capable of capturing such instantaneous behavior. To address thi...
