摘　　要：为揭示复杂海洋环境下潜艇应急上浮过程中的强非线性运动及流场特性,文章以Suboff标模为研究对象,基于RANS方程及VOF模型,建立了潜艇应急上浮运动的数值预报方法。在验证了数值造波可行性的基础上,开展了静水及波浪中潜艇应急上浮的直接数值模拟,获得了艇体运动参数的时历过程曲线及其周围流场细节信息,结果表明该方法能够较合理地描述潜艇上浮的运动规律,可为恶劣海况下潜艇上浮的安全评估提供有力支撑。A numerical method combined with dynamic overset technique is introduced to predict the strongly nonlinear motion and instantaneous flow field during submarine’s emergency surfacing.Simulations of surfacing maneuvering for a buoyantly rising submarine in calm water and waves were carried out based on Reynolds Averaged Navier-Stokes(RANS)equations and Volume of Fluid(VOF)model.Validation for numerical wave-making was performed with satisfactory results before these simulations.Reasonable motion characteristics and flow physics around the submarine demonstrate that the current method is feasible and potential for direct computation of submarine’s emergency surfacing in severe environments.
