Abstract

Results of experimental studies of the acoustic field generated by a supersonic jet on the vertical jet facility of the Institute of Theoretical and Applied Mechanics are presented. The measurements are carried out using nine microphones arranged symmetrically with respect to the jet axis. The shape of the phase front of the acoustic wave, as well as spectra of the broadband acoustic noise and discrete components with a high time and spatial resolution are analyzed. It is shown that the turbulence structure in the acoustic field is inhomogeneous and is formed by several sources.

Keywords:

supersonic jet acoustic field wave front frequency spectrum microphones discrete frequencies acoustic noise
