Abstract:

The article presents the results of experimental studies of the acoustic field generated by a supersonic jet at the installation of the VJU ITPM SB RAS. The measurements were made with 9 microphones placed symmetrically with respect to the jet axis. The shape of the phase front of the sound wave, the spectra of broadband acoustic noise and discrete components with high temporal and spatial resolution are analyzed. It is shown that the structure of turbulence 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
