Chronos-Koopman spectral analysis of bidimensional turbulent flows

We undertake a spectral analysis of a turbulent flow in a soap film using a Chronos-Koopman (CK) technique. The approach enables us to extract modes corresponding to spatial structures evolving with a single frequency, quantify their associated energy, and identify energy transfer mechanisms compati...
