Abstract:

The phenomena associated with the expansion of two bubbles resulting from the simultaneous underwater detonation of two equal charges are studied. Potential flow and incompressible medium are assumed for the calculation of the behavior and shape of the interacting bubbles. The results of this approximation compare favorably with those obtained from a more sophisticated analysis using finite difference techniques MACYL Code. The potential flow calculations are simple and require only a small portion of the machine time needed for the finite difference method. An outline is given of the fundamentals of the whipping of ships. These processes are caused by the pulsating bubble of explosions beneath the bottom of ships and are capable of doing severe damage to a ship. It is concluded that double explosions do not offer advantages In the damage effectiveness beyond that of a single explosion of equal total weight.
