| 摘 要： | 喷水推进器喷注噪声是潜艇重要的水下噪声源。文中旨在对类似的水下自由射流场噪声进行实验测量研究。用压力桶作为混响水池,在其中对扩张喷口、平直喷口、收缩喷口射流在这种压头下辐射噪声功率进行测量,比较其区别并分析水下湍射流噪声特点。

| Abstract: | An experimental investigation is done on the subject of noise testing of submerged free jet such as the flow-field induced by waterjet propulsion,which is important noise source to submarine.A pressure tank is considered to be a reverberation chamber,in which the Sound Power Level of submerged jets in-duced by straight nozzle,shrinkage nozzle,expansion nozzle are measured and compared. |
