THE INFLUENCE OF A FREE SURFACE ON UNDERWATER SPHERICAL EXPLOSIONS,
Abstract
The flow field resulting from the rupture of a pressurized sphere at a small depth beneath the ocean surface is studied. Specifically, the positions on the axis of the underwater shock, the shock transmitted into air, the disturbed ocean surface, the head of the expansion wave reflected from the surface, and the gas-water contact front are determined as functions of time. The shape of the transmitted shock front and the disturbed ocean surface are also found for a given time. Solutions are obtained by integrating a set of first order ordinary differential equations numerically with respect to time. Calculations are carried out for a sphere of helium at a pressure of 10,000 atmospheres with a ratio of depth to initial sphere radius equal to three. (Author)
