Abstract:
The report summarizes the major theoretical and experimental efforts performed during the first year of a two-year program dealing with supersonic jet noise. Specific technical results are presented on the radiation of sound sources in a jet shear layer, a theoretical study of the large scale noise producing structure of jets, the design, construction and calibration of a high temperature anechoic facility for jet noise experiments, a series of high temperature subsonic and supersonic jet noise experiments, and the design and development of a laser velocimeter for the measurement of mean flow velocity and orthogonal components of turbulence velocity.
