Energy Partition in Underwater Explosion Phenomena

Pressure-time curves, continuous from initial shock wave incidence through the second bubble pulse, are examined in the light of acoustic theory. Calculations of impulse and reversible and irreversible energy flux are made for the various phases of the phenomenon. An estimate has been made of the amount of energy dissipation associated with the propagation of the shock front. A tabulation of the energy partition is included, and it is shown that substantial quantities of energy are radiated or dissipated by mechanisms other than these taken into account in this discussion.
