Water mitigation effect under internal blast

In this work, we investigated a study of the mechanism governing the internal blast in a warship cabin and the technique for preventing it. We developed a multi-cabin structure and carried out experiments with/without water were on the cabin to record and compare such data as the blast process, the peak pressure, the specific impulse and the quasi-static pressure. The results showed that (1) water could obviously reduce the peak pressure, the specific impulse and the quasi-static pressure, that (2) within a certain range, the greater amount of TNT, the more obvious the attenuation, and that (3) water could constrain the afterburning phenomena and TNT reaction, thereby affecting the formation of the quasi-static pressure.
