摘要

[目的]水面舰船周围因非定常流动引起的流噪声问题是舰船声隐身设计技术的难点，自由液面的存在使之不同于潜艇水动力噪声计算。为解决这一问题，[方法]采用流体体积（VOF）法结合SST k-ω湍流模型计算船体外非定常流场，赋予自由液面空气声阻抗来模拟吸声边界。将船体表面脉动压力作为流噪声声源，应用声学有限元法计算水面舰船的水下辐射噪声。[结果]计算所得结果与实验值吻合良好，表明噪声源主要集中在船艏兴波处。[结论]所得结果表明所用计算方法可以较准确地模拟水面舰船的流场与声场，对水面舰船声隐身设计具有参考价值。

Abstract：

[Objectives] The problem of noise caused by an unsteady flow field around a surface ship is a difficulty facing the stealth design of ship hulls, in which the existence of the free surface makes it different from submarine hydrodynamic noise calculation. To solve this problem,[Methods] the Volume of Fluid(VOF) method and SST k-ω turbulence model are combined to simulate the unsteady flow field of the hull, and the free surface is given an air acoustic impedance to simulate the absorption boundary. The pulsating pressure of the hull surface is used as the source of the noise, and the underwater radiation noise of the surface ship is calculated with the acoustic finite element method.[Results] The results show high agreement with the experimental results and previous simulation results. The noise sources are mainly concentrated at the bow of the hull.[Conclusions] The results show that this calculation method can accurately simulate the flow field and sound field of a surface ship, and it can provides valuable reference for the acoustic stealth design of surface ships.
