Lift Equivalence and Cancellation for Airfoil Surge-Pitch-Plunge Oscillations
A NACA 0018 airfoil in freestream velocity is oscillated in longitudinal, transverse, and angle-of-attack directions with respect to the freestream velocity, known as surge, plunge, and pitch. The lift-based equivalence method introduces phase shifts between these three motions to...
