Characteristics Simulation of Submarine Vortex Velocity

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.
