Modal Analysis of Fluid Flows: An Overview | AIAA Journal

To briefly illustrate these ideas, let us provide a preview of modal decomposition. In Fig. 1, we present a modal decomposition analysis of two-dimensional laminar separated flow over a flat-plate wing [25,26]. By inspecting the flowfield, we clearly observe the formation of a von Kármán vortex street in the wake as the dominant unsteady feature.
