THEORETICAL FOUNDATIONS OF UNSTEADY HYDRODYNAMICSIN UNDERWATER EXPLOSION

Abstract

Presents the results of research related to the study of major phenomena of the underwater explosion. Outlines the basic phenomena of the impacts of underwater ex-plosion on the hydrodynamics. It is shown that the nature of the perturbation distribution depends on the physical and chemical properties of explosives. The equations of motion of compressible fluids in different wording for integration within the volume bounded by the front of the shock wave and the surface wave of depression that follows the wave of compression at some distance. Waves of compression and rarefaction intersect at the free sea surface, in the vicinity of which the conditions of rapid expansion. The boundary conditions are derived from the equations of conservation of mass, momentum and energy.
