Flow around steady and vibrating airfoil with a positive angle of attack has been
studied experimentally, using a Time-Resolved PIV (“TR-PIV”) technique. For analysis of
complex spatial dynamics of the flow the Oscillation Pattern Decomposition (OPD) method
has been used. The resulting flow dynamics is characterized by OPD modes of oscillating and
non-oscillating character, describing travelling and pulsating patterns in the flow. Topology
and frequency of dynamic modes are shown in the presented paper.
