Abstract

Abstract

Based on the detonation product state equation and the Rayleigh-Plesset equation, this paper proposed a numerical method for calculating the bubble pulsation period of underwater explosions. We can quickly calculate the bubble pulsation period of underwater explosions of different explosives. Compared with the bubble period calculation method using the JWL equation of state and the γ equation of state, the former has a smaller error (less than 3%) for TNT explosives. Additionally, by comparing the results of the RS211 explosive underwater explosion experiment, it is further verified that the numerical calculation method has good applicability for aluminum-containing explosives.
