潜艇内置隔板流体特性

为了探究隔板对隔舱特性的影响,以带流水孔潜艇内置隔板为研究对象,对潜艇内置隔舱设置不同的隔板数目,基于大涡模拟(LES)方法进行三维仿真模型进行数值模拟,分析内置隔板对潜艇隔舱阻力以及流噪声特性的影响。结果表明,内置隔板与流体的作用直接影响隔舱的整体特性。隔板数越多,隔舱阻力越大,噪声级也越高,并且阻力以及流噪声与来流速度呈正比例关系,这为潜艇内置隔板的设计提供了参考。

The Study of the Fluid Characteristics of Internal Clapboards in Submarine

To explore the clapboards′ influence on the characteristics of divided cabins,we view the internal clapboards in submarine with water holes as the research object and set different numbers of internal clapboards in submarine for divide cabins,the Large Eddy Simulation(LES) method was used to numerically simulate the three-dimensional model and the internal clapboards influenceon the characteristic of resistance and flow noise of the divided cabins was analyzed.The results shown that the effect of internal clapboards and fluid directly affected the overall characteristics of divide cabins.The more divisions,the larger resistance of divide cabins,and the higher noise level,the resistance and flow noise took on direct proportion with flow velocities,all of these could provide reference for the design of internal clapboards in submarine.
