Graphs are presented for the relative bubble energies, maximum radii, periods, and migrations of underwater explosion bubbles for four cycles of the bubble oscillation. The migration refers to the bubble maximum in each cycle. The position of the bubble minimum can be readily found by a simple computation. The graphs permit a convenient reading of these parameters for a wide range of conditions.

The migration of underwater explosion bubbles caused by gravity (buoyancy) affects the energy of the pulsation as well as period and maximum radius in the second and subsequent cycles. Experimental data on periods of explosions in various depths are analyzed, and the bubble energy is determined for five cycles of the oscillation as a function of the strength of migration. The result is given in dimensionless form which permits the calculation of periods, maximum radii, and migration for a wide range of conditions. An energy balance shows the surprising result that the bubble energy of the second cycle increases with increasing intensity of migration until a maximum is reached at a condition of strong migration. Beyond this point, the energy decreases again. This gain is found to be due to the decrease of the energy radiated by the bubble pulse.

The Physical Effects Of Conventional Explosions On The Ocean Environment written by George Anthony Young and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1970 with Explosives, Military categories.

Current knowledge of the physical effects of underwater explosions on the environment is summarized, with particular attention to the heating of water, the mixing of explosion products with water, and cratering. Theory and data indicate that thermal effects on the environment are negligible because rapid turbulent mixing reduces any temperature excess to a negligible amount within minutes. Virtually no data are available on the mixing of explosion products with water and air. However, information on the bubble and surface phenomena of underwater explosions has been utilized to provide qualitative guidance concerning the distributions immediately after a test. Existing theories of turbulent diffusion can be applied to calculate the subsequent history of the products. Knowledge of the physical effects of bottom explosions on the environment is limited to crater measurements in shallow water and some data on the behavior of explosion bubbles in deep water. Suggested programs to fill gaps in current knowledge are outlined. (Author).

The theory of the migration of the bubble formed by the gaseous products of an underwater explosion is review, particular care being taken to state the assumptions involved and to indicate their validity. The theory is then compared with the experimental data available at the Underwater Explosives Laboratory by graphical mean. The comparison show that the theory correctly predicts the migration for charges weighing less than 25 lbs but predicts too great a migration for larger charges except when the larger charges are very deep.
