Three-dimensional analysis of incompressible flow over an open cavity using direct numerical simulation: From linear to saturated regime

The features of the incompressible flow over a rectangular open cavity are studied both numerically, using linear stability analysis, and experimentally in previous works by the authors. Those approaches refer to different states of the flow. The numerical analysis refers to a linear small perturbation superimposed over a two dimensional steady state, while the experimental work studies the complete saturated flow regime, with spanwise walls.
