Underwater explosions

Abstract

An underwater explosion is an extremely complex physical and chemical process. As the explosive charge detonates, it causes the sudden release of chemical energy and produces high-temperature and high-pressure gas that quickly diffuses around underwater. The shock wave generated by an underwater explosion propagates radially in water and its peak pressure of the shock wave is related to the charge and relative explosive distances. Underwater explosion load can be divided into impact load and bubble action load, which can cause local or global damage to a ship or submarine. Hence, the measurement of underwater explosion load is very important for ship designing purposes. In the present short review various aspects of underwater explosions are presented in some detail.
