title = "Correlations in the Near-Field of a complex supersonic jet using time-resolved schlieren imaging",
abstract = "Supersonic flow from a three-stream non-axisymmetric jet is visualized using time resolved schlieren photography (up to 400,000 frames per second) while pressure on the aft deck plate of the nozzle is simultaneously sampled using kulites. Time series are constructed using the schlieren photographs and conditioned to reduce the effects of signal drift where necessary. The effect of conditioning on the frequency content of the signals and the results of multiple signal cross correlations is examined. Signals constructed from individual points in a spatially down-sampled representation of the flow field are cross-correlated with a reference point, and trends in the subsequent visualization of information propagation in the flow are noted. This process is repeated for band-pass filtered signals to separate the modes of propagation of individual frequency bands.",

note = "Funding Information: This work would not have been possible without the convergence of multiple resources, for which we are grateful. The near-field analysis is supported in part by AFOSR grant number FA9550-15-1-0435, Dr.D. Smith, Program Manager. The other support was provided by AFRL, Turbine Engineering Division, under an SBIR contract to Spectral Energies LLC. In particular, we appreciate the loan of mirrors from AFRL and camera from Spectral Energies, LLC. We also had partial support from Syracuse University, and benefited from extensive interactions with all members of the Glauser Group at Syracuse. Special thanks to Andy Magstadt and Matthew Berry for the long days and late nights spent in the lab to collect this data, and Han Pham for assisting in its analysis.
