1.
Based on boundary layer theory and radiated noise theory of boundary layer transition,the conventional torpedo flow noise prediction models are analyzed and compared,and an integrated prediction method of torpedo flow noise is hence presented.
基于边界层理论和转捩区声辐射理论,在对传统鱼雷流噪声预报模型进行分析和对比的基础上,提出了一种鱼雷流噪声的综合预报方法。
5) Mass-bubble Cavitation
空泡群噪声
6) torpedo noise simulator
鱼雷噪声模拟器
1.
To meet the need of research on some sonar system, the paper designs a digital torpedo noise simulator, which can conveniently provide real-time and multi-parameter sonar signals in the digit.
本文针对某型声纳的研制需要，设计开发了一种数字鱼雷噪声模拟器。
补充资料：噪声等效声级（简称LEQ）
噪声等效声级（简称LEQ）：是指在规定的时间内，某一连续稳态声的A\[计权\]声压，具有与时变的噪声相同的均方A\[计权\]声压，则这一连续稳态声的声级，就是此时变噪声的等效声级。噪声等效声级(分贝）数值越小越好。
