Investigation on the cavitation effect of underwater shock near different boundaries

open access: yes, 2017
When the shock wave of underwater explosion propagates to the surfaces of different boundaries, it gets reflected. Then, a negative pressure area is formed by the superposition of the incident wave and reflected wave.

Propagation Losses of Underwater-Explosion Shock Waves [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1963
At very great ranges from an underwater explosion, the propagation losses of discrete frequency components of the shock wave appear to follow acoustic laws. If a reference range near the charge is used, however, the high-amplitude source characteristics must be taken into account.

UNDERWATER SHOCK WAVE INTERACTION WITH AIR BUBBLE

open access: yesJOURNAL OF THE FLOW VISUALIZATION SOCIETY OF JAPAN, 1987
The present paper reports the visualization study of the initiation of a shock wave generated by a rebounding bubble and a micro-jet induced when the bubble is collapsed. The underwater spherical shock wave is obtained by using a 10 mg silver azide(AgN3) pellet, and visualized by using double exposure holographic interferometry.

Study on the Pressure Characteristics of Shock Wave Propagating across Multilayer Structures during Underwater Explosion

open access: yesShock and Vibration, 2019
The propagation of the shock wave across multilayer structures during underwater explosion is a very complex physical phenomenon, involving violent fluid-structure interaction (FSI) problems. In this paper, the coupled Eulerian–Lagrangian (CEL) method in

UNDERWATER SHOCK MODELING

open access: yes, 2019
Underwater explosions and their devastating effects are not new to the U.S. Navy; however, accurately modeling and scaling them for research and development is always an area of interest for anyone trying to protect the lives of the men and woman who serve on ships.
