Abstract
In this report, it was described that the experimental results on the noise characteristics and discrete sound generation in a supersonic jet issuing from a nozzle with a divergent exit. The shock waves were visualized by Schlieren method or a high-speed video camera included its system, and the motion of the over compression regions were studied by the digital image processing. It was clarified that the behavior of over compression regions were periodical, and these periods related to the cause of frequency distribution noise.
