摘要
内孤立波是密度分层水体中产生并传播的一种特殊波动。在这一过程中,如果遇到地形变化复杂的浅海区域,内孤立波会因地形的影响而表现出变形、失稳和破碎,并在海底附近区域产生强烈的紊动混合和能量耗散。其可使海洋结构发生移位或扭曲,也可削弱潜艇的运动稳定性而失去控制。这一系列过程的动态特性一直是国内外学者的研究焦点。该文从物理试验、数值模拟2方面总结海洋内孤立波常见的研究方法,并归纳海洋结构物和潜体在分层强剪切环境下受到内波的作用特性,这对掌握内孤立波特性以及探索海洋资源和海洋工程建设具有一定的工程意义。
Internal solitary wave is a special wave generated and propagated in density stratified water.In this process,if the shallow sea area with complex topography is encountered,the internal solitary wave will show deformation,instability and fragmentation due to the influence of topography,and produce strong turbulent mixing and energy dissipation in the area near the seafloor.It can not only shift or distort the marine structure,but also weaken the motion stability of the submarine and lose control.The dynamic characteristics of this series of processes have been the research focus of scholars at home and abroad.In this paper,the common research methods of internal solitary waves in the ocean are summarized from two aspects of physical experiments and numerical simulation,and the characteristics of marine structures and submerged bodies subjected to internal waves in a layered strong shear environment are summarized.This has a certain engineering significance for mastering the characteristics of internal solitary waves and exploring marine resources and marine engineering construction.
