Abstract
Time-resolved Particle Image Velocimetry (PIV) measurements
in two perpendicular planes are used to reconstruct a flow in an axisymmetric facility in both time and space. The reconstruction is based on Proper Orthogonal Decomposition (POD) and is used to distinguish between spatial and temporal variations. The flow in a cylindrical cavity with a rotating lid of a height of three radii and a Reynolds number of about 3500 is used as example. The reconstruction identifies a series of flow structures
including axisymmetric vortex breakdown and distinct vortex
structures along the cylinder wall.
