Thesis (Ph.D.)--University of Minnesota, 2008.

Underwater Explosions (UNDEX) can be modeled as a two-part process. The first part is the shock wave generated from the explosion, while the second part is the generation of a secondary-wave pressure pulse that is formed by the contraction of the gaseous products created by the explosion. The main contribution of this investigation to the theory of UNDEX is the full quantification of the secondary wave. The impact of these waves on the hull of a marine vessel is the other major focus of the work. The vessel in question is a test facility used to determine the impact tolerance of unhardened electronic equipment. In summary, the problem falls in the category of Fluid-Structural-Interactions (FSI). The global goal of the investigation is to create an all-numerical simulation to replace the costly and marginally accurate experiments presently employed to evaluate the response of unhardened (commercial off-the-shelf) electronic equipment to explosion-related, high-impact forces.

520 $a The fluid flow phenomena, including the shock wave, secondary wave, and cavitation, give rise to the impingement of high impact forces on the hull of the vessel. In turn, these forces are transmitted from the hull to the deck to which the electronic equipment is fastened. The magnitude and the frequencies of the accelerations experienced by the deck are determined. This information is universal in the sense that it can be applied to any type and configuration of electronic equipment and maritime vessel.
