摘要：

An experimental study of the flow field and acoustic properties of a low Reynolds number (Re congruent 3600), M equals 0. 9 jet was performed in a low pressure anechoic test chamber. The mean flow field was surveyed with a conventional Pitot pressure probe and flow fluctuations were detected with a normal hot wire probe. Also, condenser microphone measurements were made in the acoustic field. The major goal of the study was to develop a better understanding of the noise generation mechanisms of subsonic jets.
