【摘要】 为了掌握潜艇在近自由液面航行时的性能特征以帮助其设计优化。本文采用CFD(Computational Fluid Dynamics)方法,基于Volume of Fluid (VOF)模型和Large Eddy Simulation (LES)湍流模型对在近自由液面航行的Sub-off的流场开展仿真计算,就相关工况开展方法的验证(verification)和证实(validation),提高数值仿真的可靠性;接着对不同航速、潜深下多个工况进行数值计算,对比分析潜深对潜艇阻力的影响。计算表明:潜艇的近自由液面航行中,兴波波系耦合作用是潜艇阻力变化的重要原因。数值仿真结果为潜艇近自由液面航行的研究提供新颖的研究思路和研究方向。更多还原

【Abstract】 In order to grasp the performance characteristics of the submarine sailing near the free surface to help its design optimization.This paper adopts CFD(Computational Fluid Dynamics)method,based on volume of fluid(VOF) model and large eddy simulation(LES) turbulence model is used to simulate the flow field of sub off sailing near the free surface,and the verification and validation of methods are carried out for relevant working conditions to improve the reliability of numerical simulation;then,the numerical calculation is carried out for several working conditions under different speeds and depths,and the influence of diving depth on submarine resistance is compared and analyzed.The results show that the coupling effect of wavemaking system is an important reason for the change of submarine resistance in near free surface navigation.The results of numerical simulation provide a new idea and direction for the research of submarine near free surface navigation.更多还原
