Investigating mode competition and three-dimensional features from two-dimensional velocity fields in an open cavity flow by modal decompositions
... We applied both POD and DMD modal decompositions. As expected for a flow whose kinetic energy is dominated by the mean-flow, the first spatial POD mode is close to the mean flow. The chronos of the next two dominant POD ...
