Application of Proper Orthogonal Decomposition to High Speed Imaging for the Study of Combustion Oscillations

Abstract: The flame structure and characteristics generated by an industrial low emission, lean premixed, fuel swirl nozzle were analyzed for understanding combustion oscillations. The experimental facility is located at the Advanced Propulsion and Power Laboratory (APPL) at Virginia Tech. The experiments were carried out in a model optical can combustor operating at atmospheric pressures. Low-frequency oscillations (<100 Hz) were observed during the reaction as opposed to no reaction, cold flow test cases. The objec… Show more

“…Gadiraju et al 16 used the POD for the post-processing of flame images of an industrial gas turbine nozzle. The detection of the main features characterizing the combustion fluctuations represented the main goal of this work: it is demonstrated how the large-scale coherent flow structures (i.e., the PVC) are crucial for the self-sustained combustion instabilities even close to the lean blow-out of the flame.…”
