Abstract

Abstract

To explore the mitigating mechanism of detonation of a high explosive surrounded by water, experiments of explosion with and without water were carried out in an open-ended steel cylinder. The particle velocity and the displacement of the outer surface of the cylinder were obtained by an optical-fiber displacement interferometer. The results indicate that shock wave will not be formed in air by the product of detonation until the water surrounding the product is separated to a fissure, which causes the later appearance and lower magnitude of shock wave with a longer duration compared with an explosion without water. It means that two-dimensional or three-dimensional numerical models are required to conduct the simulations of explosions with water. It is also observed that the augment of blast load decreases with the decrease of the density of the water container as well as its thickness.
