Investigation of Screech in Supersonic Jets Using Modal Decomposition
Conference contribution, 2014

The present study attempts to identify the eigenmodes that are associated with the screech mechanism by means of Dynamic Mode Decomposition (DMD) and a method based on the Arnoldi eigenvalue algorithm, respectively.
