Study On The Method Of Generating Large Internal Waves From Submarine Array Motion

Large internal waves in the ocean will pose a huge threat to marine structures such as submarines.Our country’s No.372 submarine has encountered internal ocean waves and suffered a serious fall.Therefore,a technology of generating large internal waves from the movement of real sea submarine array is proposed,and its characteristics of generating internal waves can be used as the basis of reconnaissance,which is of great significance to improve the combat ability of our navy.The main content of this paper is to first compare and analyze the various generation methods of internal waves in the laboratory,discuss the characteristics of various wave-making methods and the limitations of extending to the real sea,and propose the application of submarine array motion through pre-experimental research and combined analysis.Internal wave generation method.Secondly,physical experiments are carried out for the above-mentioned ideas,considering the influence of the submarine’s motion on the phenomenon of internal wave generation when the submarine array is in different longitudinal positions,moving speeds,moving distances,and array distribution.Finally,the commercial software Star-CCM+ was used to conduct a numerical simulation study on some working conditions of the physics experiment to verify the accuracy of the numerical method,and then break the limitation on this basis,and conduct an extended simulation study on the length and width of the space.Research shows that submarine array motion is an effective and feasible method for generating internal waves.When the moving distance is long enough,internal solitary waves with a certain amplitude can be generated after it stops moving.
