Abstract
In this study, a turbulent jet flame is studied using simultaneous high speed laser diagnostics. Information from CH and OH PLIF, as well as stereoscopic PIV was obtained on a single plane at a frequensy of 10 kHz. Analysis of the OH PLIF and velocity data using Extended POD, as well as OH LIF data using DMD, showed that in this particular flame the average of the signal is by far the main component of the signal, with no outstanding strong feature. Such diagnostics and post-processing methods open new perspectives on the experimental study of flow-flame interactions and flame dynamics.
