Abstract: The paper presents the results of a research on bubble curtain behavior subjected to underwater shock waves generated by a TNT blast. The main objective was to numerically evaluate the effects of underwater explosion before and after the interaction with the bubble curtain. Simulations using ANSYS AUTODYN were performed for a 2D model, including the bubble curtain, focusing on the profile of the shock wave and the overpressure generated by the underwater explosion. The idea of utilizing controlled underwater explosions has been widely used in operations like neutralization of unexploded maritime mines, blasting for ports infrastructure construction, offshore wind turbine installation and antifouling methods. Mainly because of these large number of underwater explosion uses there is always an open domain for mitigation their effects.

Keywords: simulation, underwater shockwave, gas bubble, biphasic media, bubble curtain.
