SHEAR LAYER INSTABILITY AND FREQUENCY MODES INSIDE AN OPEN CAVITY

The dynamic behaviour of the vortex structures occurring in a cavity, in interaction with an upstream wall flow, drives the fluid confinement inside the cavity. This presentation concerns the coupling between the shear instability process and the mechanisms of frequency selection which depend on the size of the cavity. The analysis is based on an experimental exploration of the flow (LDV, PIV) and on direct numerical simulation.
