水下爆炸气泡及其对结构毁伤研究综述
Review of the research on underwater explosion bubbles and the corresponding structural damage
摘要
Abstract
The near-field underwater explosion can cause severe damage to warships. Specifically, studies reveal strong coupling interaction between underwater explosion bubbles and the structure that are initially damaged, which could generate further damage to the structure. The interaction between underwater explo⁃sion bubbles and different boundaries, including the free surface, the seabed, and the elastic structure, is the research focus in the field of fluid mechanics and fluid-structure interaction. However, urgent problems remain unsolved. This study pays much attention to the structure damage caused by underwater explosion bubbles, namely the research status of this field, including experimental, theoretical, and numerical as⁃pects. Particularly, the dynamic characteristics of the coupling of bubbles are studied by considering the structure elasticity, free surface effect, the compressibility of the flow field around the bubble, assuming that the underwater explosion shock wave results in structural break. Furthermore, the initial shape of the bubble and the temperature variation inside the bubble are investigated, exploring the phenomenon of"cav⁃ity suction"as well as the characteristics of the jet and the load law of the bubble.关键词
