Numerical Studies Regarding Underwater Detonation

AbstractThe article presents the results of a numerical study regarding a primary explosive detonation in aquatic medium. The main purpose of this study is the evaluation of underwater explosion effects in order to conceive an effective attenuation method. Since the development of mass destructive guns, explosive materials have been the most effective means to threat live. However, the most recent researches have proved that these instant pressure generators could be used also in positive purposes. In this way, controlled demolition, development of new ballistic materials, simulation of meteorite impact on earth, lithotripsy, mining and blasting wouldn’t have been possible without the aid of explosions. The theme of this article is born from the idea of utilizing controlled underwater explosions as antifouling means. The protection of sea fauna and flora is a priority so the actual antifouling method are either toxic or complicated and costly inefficient. Numerical simulations performed in order to achieve the purpose of this work consist in utilizing ANSYS AUTODYN soft to evaluate the effects of 10mg detonation of a primary explosive. Numerical researches are based on experimental data from laboratory tries and have the main purpose validation of the results with the practical ones
