Underwater spherical shock wave
2013 Abstracts IEEE International Conference on Plasma Science (ICOPS), 2013Summary form only given. The results of experimental and numerical studies of spherical implosion of converging spherical strong shock waves (SSW) generated using underwater electrical explosion of spherical Cu wire arrays are reported. In the experiment, a ~ 4 kJ pulse generator with discharged current amplitude -300 kA, and a rise time of ~ 1 μs was ...

Underwater oblique shock wave reflection
Physical Review Fluids, 2018Domains of regular and irregular reflection for underwater oblique shock waves have been identified theoretically. We compare the Tait and Mie-Gr\"uneisen equations of state in their ability to demonstrate physics of shock wave reflection and find implications for designing blast mitigation devices.

An underwater explosive shock gun
Journal of Fluid Mechanics, 1967A theoretical study is made of a simple design for an underwater shock gun, which consists of a chamber in the form of a hollow circular cone, with a spherical sector of explosive charge fitted into the apex. When the explosive is initiated at the apex, the resulting sector of a spherical blast wave will be diffracted by expansion waves moving inwards ...

Underwater hydraulic shock shovel control system
Journal of Marine Science and Application, 2008The control system determines the effectiveness of an underwater hydraulic shock shovel. This paper begins by analyzing the working principles of these shovels and explains the importance of their control systems. A new type of control system’s mathematical model was built and analyzed according to those principles.

An underwater shock wave research device
Review of Scientific Instruments, 1991It is the purpose of this article to describe the design, construction, and operation of a highly versatile, low cost experimental facility to produce, by electrical breakdown of water, weak underwater shock waves in the 50 to 2000 bar range. The device as a whole is described and then the electrical circuit used to generate the shock waves is ...
