DMD algorithms for experimental data processing in combustion

Abstract : The present study aims at investigating the parameters influencing the quality of the dynamic mode decomposition when applied to experimental data from turbulent com- bustion. It is shown that the choice of the snapshots and the decomposition methodology have a strong influence on the mode spectra and the frequency resolution. Finally, the simultaneous decomposition of experimental data is performed with optimal parameters showing the quantitative information which can be obtained to highlight the coupling mechanisms involved in combustion instabilities.
