Flow Structure of Recirculation Zone behind Backward Facing Step in a Narrow Channel

Original language description

Structure of the flow-field behind a backward-facing step in a narrow channel is studied experimentally using time-resolved PIV technique. The channel width is 4 step heights, Reynolds number based on the step height was about 12 thousands. The flow-field behind the step is strongly dynamical in nature. Instability of the free shear layer of Kelvin-Helmholtz (K?H) type is studied in details using simple averaging, Proper Orthogonal Decomposition (POD), and Oscillation Pattern Decomposition (OPD) methods. Typical time-mean as well as dynamical structures are to be presented being in the form of systems of vortex trains.
