An engineering calculation method on the bubble pulse period of underwater explosion

Based on the experiment research of former scientists, an engineering calculation method on the bubble pulse period of underwater explosion was established by introducing the correction factors of cylindrical and spherical charge forms into the relationship between explosion heat and bubble pulse period was revealed, and the exact calculation was realized by the method at the different explosives and charge forms. The method was verified by an experiment. The error of results between the experimented and the calculated is smaller than 5%. The method provides important science basis for designing formulation and evaluating performance of underwater explosive.
