水下航行器纵缝开孔水动力噪声特性研究
Study on hydrodynamic noise characteristics of underwater vehicle with longitudinal water hole
摘要
Abstract
Based on the numerical method,the influence of longitudinal slit opening on the hydrodynamic noise of underwater vehicle was explored.The validity of the numerical method of hydrodynamic noise was verified by low-noise gravity water tunnel test.On this basis,the Suboff scale model was taken as the research object,and the grid independence analysis was carried out by using large eddy simulation,DES(detached-eddy simulation),FW-H(Ffowcs Williams-Hawkings)equation and flow-induced noise theory.The characteristics of flow noise and flow-induced noise of longitudinal slit underwater vehicle were explored,and the dominant components of hydrodynamic noise at different speeds were determined.Calculation results show that the surface opening destroys the continuity of the shell,disturbs the flow of the fluid,increases the fluctuating load on the surface of the vehicle,and then increases the flow-induced noise of the underwater vehicle and becomes the main component of the hydrodynamic noise.At the speed of 3 m/s,the flow noise of the underwater vehicle decreases after the opening of the hole,and the flow-induced noise increases.The hydrodynamic noise increases after the superposition of the two.With the increase of the speed of the underwater vehicle,the flow noise and the flow-induced noise increase to varying degrees,but the flow-induced noise is always the main component of the hydrodynamic noise of the underwater vehicle after the opening of the hole.关键词
