Molecular velocity imaging of supersonic flows using pulsed planar laser-induced fluorescence of NO

摘要: A technique is described for imaging components of velocity in a gaseous flow field by using pulsed planar laser-induced fluorescence. The based on the fluorescence detection Doppler-shifted absorption that results when spectrally narrow line excited with broadband laser. Results obtained Mach 7 underexpanded supersonic jet, seeded NO, are presented. practical extension this to single-shot measurements two discussed.
