Formation of a plume by the underwater explosion of a toroidal charge

The formation of a plume by the underwater explosion of a toroidal-shaped charge is interesting to study because the gas bubble formed as a result of the explosion assumes the shape of a torus during its evolution. The present paper is devoted to a further investigation of the plume due to the explosion of a toroidal charge. The characteristic horizontal size of the plume, the problem concerning the motion of the free surface of the liquid, the conditions for which the maximum uplift of liquid into the plane of symmetry assumes an apriori value, and the motion of the plume in the vertical direction are all studied.
