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: 水下爆炸,特别是近场水下爆炸,会对舰船结构造成严重的毁伤,研究表明,水下爆炸气泡将与含初始毁伤的结构产生强烈的耦合效应,造成二次毁伤。水下爆炸气泡与自由面、壁面、弹性结构等不同边界的相互作用是流体力学和流固耦合领域的研究热点,有很多机理性问题亟待解决。围绕水下爆炸气泡对结构的毁伤,从实验研究、理论研究、数值研究等方面阐述该领域国内外的研究现状。在现有的研究动态中,仍存在着不足,一些问题仍需深入研究,例如,要研究水下爆炸冲击波对水中结构造成破口后,气泡与具有初始破口的不完整边界的耦合动力学特性,并计入结构的弹塑性、自由液面效应、气泡周围流场的可压缩性、气泡的初始形状以及气泡内部的温度变化,探索气泡的“腔吸现象”、射流特性及其载荷规律。

     

    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.
