N2 - Three-dimensional simulation of air injection into a liquid (water, liquid lead) at large pressure drops in a three-dimensional formulation has been carried out. A significant difference in the formation of the air volume form at injection of water and liquid lead is shown. The instability of the interfacial surface in the form of annular waves and axial cavity on the upper surface of the slug has been revealed in three-dimensional calculation. For the three-dimensional case the gas-dynamic structure of the compression jumps and the Mach disk is found to be more pronounced for the supersonic underexpanded jet inside the slug.
