Experimental research on bubble pulse of small scale charge exploded under simulated deep water

  • For investigating bubble pulse of small scale charge exploded under deepwater in the laboratory, an experiment platform of charge exploded under simulated deepwater is established by means of adding atmospheric pressure over the water surface to increase the hydrostatic pressure. Experiments of 3 small scale charges exploded under different simulated deepwater environments are conducted. Images of bubble pulse process are gained. The equivalence between experiments of small scale charge exploded under simulated deepwater and experiments under free-field is validated. The variations of the period and the maximum radius of bubble pulse depending on the water depth are analyzed. Passing through these experiments, the reflection effect from the containment vessel shell can be neglected for the bubble pulse process, and the simulated deepwater environment can be regarded as real free-field deepwater environment. When increasing the hydrostatic water depth, the attenuation coefficients of the period and the maximum radius of bubble pulse of small scale charge exploded under deepwater are -0.83 and -0.364, respectively.

Abstract: For investigating bubble pulse of small scale charge exploded under deepwater in the laboratory, an experiment platform of charge exploded under simulated deepwater is established by means of adding atmospheric pressure over the water surface to increase the hydrostatic pressure. Experiments of 3 small scale charges exploded under different simulated deepwater environments are conducted. Images of bubble pulse process are gained. The equivalence between experiments of small scale charge exploded under simulated deepwater and experiments under free-field is validated. The variations of the period and the maximum radius of bubble pulse depending on the water depth are analyzed. Passing through these experiments, the reflection effect from the containment vessel shell can be neglected for the bubble pulse process, and the simulated deepwater environment can be regarded as real free-field deepwater environment. When increasing the hydrostatic water depth, the attenuation coefficients of the period and the maximum radius of bubble pulse of small scale charge exploded under deepwater are -0.83 and -0.364, respectively.
