The porous airfoil, inspired by avian wing morphology, exhibits complex flow-induced vibrations (FIVs) that significantly impact aerodynamic performance. This study employs computational fluid dynamics (CFD) methods to investigate FIV mechanisms of the porous airfoil through parametric analyses of a...
