Abstract:This paper describes experimental research on the acoustical aspects of an axially-symmetrical radial diffuser. Tests were made at high subsonic and supersonic speeds at the diffuser entry, using compressed air. The results are analyzed from the point of view of the internal flow and Lighthill's theory of sound generated aerodynamically. The outstanding features of this diffuser are a high efficiency in subsonic and supersonic ranges and extreme shortness and powerful sound attenuating capacity. The noise level of a supersonic nozzle at Mach 4.0 was reduced from about 110 dB to 80 dB.
