Underwater Explosion Dynamics: Its Origin, Development, and Prospect

Abstract

Underwater explosion dynamics is a specialized discipline that studies the physical effects of the interaction between the products of underwater detonations of energetic materials, including explosives and water. The characteristics of multi-disciplinary interaction and penetration are particularly prominent. Based on a thorough literature analysis, this paper discusses the research scope of underwater explosion dynamics and summarizes its process of origin. Then, from the perspectives of theoretical understanding and technological development, the paper outlines the current state of development of underwater explosion dynamics, focusing on underwater explosion shock waves, bubbles, boundary effects, and deep-water explosions. Finally, suggestions for the development of underwater explosion dynamics are proposed and discussed in three aspects: underwater explosion loads, underwater explosion damage, and the application of new technologies. This paper not only provides useful references, inspirations, and ideas for researchers engaged in underwater explosion research but also serves as an introduction and guideline for non-professional field workers who have an urgent need for relevant professional knowledge of underwater explosion dynamics.
