The Harmonic Pitching NACA 0018 Airfoil in Low Reynolds Number Flow
EnergiesThis study investigates the aerodynamic performance of a symmetric NACA 0018 airfoil under harmonic pitching motions at low Reynolds numbers, a regime characterized by the presence of laminar separation bubbles and their impact on aerodynamic forces. The
