Flow around steady and vibrating airfoil NACA 0012 has been studied experimentally using time resolved PIV technique. The dynamics of the flow is analysed using Oscillation Pattern Decomposition method applied on the velocity vector-fields. The flow-field dynamics is characterized by the OPD modes of oscillating and non-oscillating character capturing traveling and pulsating patterns. The unsteady velocity field is affected by both wing vibrations and inherent flow dynamics. Role of the airfoil vibrations in the flow dynamics is to be shown.
