The motivation of the experiments is to study the flow dynamics and topology behind an airfoil. The airfoil is modeled by a simple flat plate with rounded leading and trailing edges. To obtain an information about the 3D structure of the flow the stereo PIV method is applied in the plain behind the plate oriented perpendicularly to the main flow. The flow dynamics topology could be studied using POD method revealing the most energetic fluctuation topologies. The POD is typically applied on a 2-component vector fields. In the presented paper the POD will be used for 3-component vector field resulting from the stereo PIV method.
