潜艇涡流速度特性数值仿真

Characteristics Simulation of Submarine Vortex Velocity

潜艇涡流以其持续时间长、尺度大、无法消除等特点,成为各国海军探潜技术的研究热点。文中研究潜艇涡流特性及潜艇操纵产生的涡流运动特性,探索提升反潜作战能力的新途径。通过对3型潜艇在相同深度(200m)下的涡流运动速度与航速数值仿真,以及相同航速(10kn)下的涡流水平运动速度随深度变化数值仿真,可以发现涡流运动速度受潜艇尺寸、运动速度、潜深及浮力等参数影响,其中浮力为涡流运动速度的主要影响因素。文中研究可为潜艇涡流速度特性提供有力支撑。

Submarine vortex detection technology has become a research hotspot for navies in various countries due to the characteristics of the vortex, including long duration, large scale, and inability to eliminate. The submarine vortex characteristics and the motion characteristics of the vortex generated by submarine maneuvering are discussed in this paper, along with some new ways to improve anti-submarine operational capability. A simulation analysis of three types of submarines was carried out, analyzing the vortex motion speed and ship speed with the same depth(200 m) and the vortex horizontal movement speed with depth under the same ship speed(10 kn). The simulation results show that the vortex motion speed is related to parameters such as the size, motion speed, diving depth, and buoyancy of submarines,among which the buoyancy is the most significant. The findings in this paper can provide references for the study of the submarine vortex velocity characteristics.
