Study on the explosion load characteristics of aluminized explosives near the wall in deep water.

This article focuses on the experimental and numerical investigation of near-wall explosion load characteristics of aluminized explosives in deep water environments ranging from 200 to 2000 meters. The study examines how water depth and aluminum powder content influence shock wave loads, bubble pulsation, jet loads, and their impulses on nearby structures, using a pressure tank to simulate deep-sea conditions and validating results with numerical models. Key findings include that increased water depth enhances the afterburning energy of aluminum powder, extending shock wave positive pressure duration and impulse, while the dimensionless distance parameter γ governs jet formation timing and velocity, which are critical to the jet’s destructive capability. The research provides quantitative insights relevant to the design of deep-water weapons and protective measures for underwater infrastructure.
