Paper Abstract

The report presents the results of a study of the location of excitation areas of discrete of acoustic tones in axisymmetric supersonic jet in its turbulent breakup. Peak amplitudes of laser beam intensity spectra found at frequencies of discrete tones vary markedly both across the section of the jet, and with change the distance from the nozzle. This allows to trace the configuration of the jet area, where corresponding tones excitation arises. We presents the distribution of the screech excitation areas corresponding to different mechanisms of his arousal.
