UNDERWATER EXPLOSION PHENOMENA: THE PARAMETERS OF MIGRATING BUBBLES

Abstract

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.
