概要
- 論文の詳細を見る
This paper presents an experimental study to explore the noise reduction of an under-expanded supersonic jet. As a novel method to obtain the noise reduction, a rigid wire is inserted into the under expanded supersonicjet stream. The experimental results show that the wire device significantly changes the shock and acoustic wave structures, leading to substantial noise reduction, compared with the under expanded jets without the wire device. According to the jet noise measurement, the + type wire device leads to the overall sound intensity reduction of about 15dB.
