• W4282577602 abstract "The effect of a conical reflector upstream of the nozzle exit of a supersonic underexpanded jet was studied experimentally. The jet had a fully-expanded Mach number of 1.34, and the reflector half-angle was sixty degrees. Experiments were performed using a near-field linear microphone array that included one continuously-scanning sensor enabling high spatial resolution. The isolated jet emitted well-known screech mode B (lateral oscillation), with the fundamental tone and its harmonics appearing prominently in the sound pressure level spectrum. Addition of the reflector caused significant changes in the modal emission pattern, with new oscillation mode E appearing prominently, in conjunction with mode B. The near-field data obtained from the continuous-scan experiments were processed using a partial fields decomposition approach, in which the fixed sensors were utilized as the phase references. The technique allowed the construction of a global cross-spectral matrix based on the finely-spaced locations of the scanning sensor. Beamforming maps and deconvolved noise source distributions were computed using the global cross-spectral matrix and provided information on the structure of the noise source for the two jets. Cross-beamforming indicated significant coherence between shock cells at the screech frequencies. The partial fields were decomposed into radiating and non-radiating components, including separation in upstream- and downstream-propagating events. This information was used to assess the location of the screech sources for modes B and E with a high degree of spatial resolution. Finally, the tonal partial fields were propagated to the acoustic far-field using the boundary element method. The resulting directivity of the sound pressure level spectrum is in fair agreement with experimental results for the same jets." @default.
