Descripción
The flow over the incompressible open cavity has been studied both numerically and experimentally in previous works by the authors [6,16]. In these studies the in-depth linear stability analysis of the problem provided a detailed description of the flow features in the linear regime, where span-wise periodic perturbations over a steady two-dimensional flow were studied. The experiments conducted in said work, with span-wise walls, show the flow in a saturated state. The main structures that appear in the flow were identified as three-dimensional centrifugal modes. Even if the flow conditions for these two approaches are different, common features appear in both: the spatial structure of the modes in the saturated regime according to the experiments is the one predicted by linear analysis, but there is a shift in frequencies for the oscillating modes. The present work uses a three-dimensional non-steady direct numerical simulation (DNS) with periodic span-wise conditions to study the effect of saturation. In order to analyze the DNS results a Dynamic Mode Decomposition (DMD) was used.
