摘　　要：为了掌握潜艇下潜机动航行模式下对海表面尾迹特性的影响规律,应用CFD技术,基于自由面兴波及其辐聚辐散场分析法,对分层流中实尺度潜艇进行下潜机动模拟,通过监测自由面速度场求散度,研究潜艇下潜状态对自由面及跃层流场的影响,研究分析了不同海洋分层环境对潜艇下潜机动的影响。研究表明:潜艇进行强机动航行时,对自由面即海洋内部扰动较为剧烈,当潜艇以不同下潜攻角与航速下潜时,对流场的扰动较匀速直航状态差距较大。The dive maneuver of a submarine in stratified flow is simulated by CFD technology based on the free surface wave making and its convergence and divergence field analysis to understand the influence of submarine diving mode on the wake characteristics of the sea surface.The divergence is obtained by monitoring the free surface velocity field,and the influence of the submarine dive state on the free surface and the jump layer flow field is comprehensively studied.Moreover,the influence of different ocean stratified environments on submarine dive maneuvers is studied and analyzed.Studies show that when the submarine is navigating with strong maneuvers,the disturbance to the free surface,that is,the interior of the ocean,is remarkably severe.When the submarine dives at different angles of attack and speed,the disturbance of the flow field is larger than that in the state of direct sailing at a constant speed.
