Effect of properties of the source on the action of explosions in air and water

Results of an experimental study of parameters of the shock wave and explosion products in the near zone of explosions in air and water with a wide range of variation of explosion heat and charge density of high explosives are presented. It is shown that the influence of these characteristics on the action of explosions in the near zone can be characterized by one parameter: volume concentration of energy in the source. A change in this parameter involves a significant redistribution of energy between the explosion products and the shock wave, which can affect brisance and violate the energy similarity of explosions.
