Experimental Study on the Underwater Explosion Bubble Near deformable boundary

Abstract

Studying near-field underwater explosions is important for the research of submersible and underwater explosive weapons. In this study, we conducted experiments to investigate the coupling of near-field underwater explosion bubbles with titanium alloy plates and steel plates. Our findings show that the boundary of a titanium alloy plate causes the first pulsation period of a bubble to be longer than in the free field, while the boundary of a steel plate causes the first pulsation period of a bubble to be shorter than in the free field. Furthermore, we simulated the process of the explosion and found that changes in the period may be caused by ventilation.
