“…Additionally, changing the standoff distance did not significantly affect the transmitted peak overpressure. These two findings agree qualitatively with numerical models of water shields studied by M. Cheng and associates [3].…”

“…Water configurations considered include sprays, confined masses of water, and water sheets [2]. Numerical models of water sheets by M. Cheng and associates predicted that at a larger distance from the blast source, more water is needed to obtain the same level of mitigation seen at smaller distances [3]. From these models it was also predicted that the peak pressure transmitted through the water was not significantly affected by changing the standoff distance.…”

Abstract. An explosion yielding a blast wave can cause catastrophic damage to a building and its personnel. This threat defines an immediate importance for understanding blast mitigation techniques via readily available materials. An unconfined mass of water in the form of a free flowing sheet has been experimentally tested and analyzed as a readily available mitigant. A single water sheet, with an approximate sheet thickness of 3 mm, was experimentally tested with an explosively driven shock tube at three different standoff distances. At the strongest shock strength considered, the water sheet decreased the peak overpressure of the blast wave by 80% and the impulse by 60%. Additionally, the peak overpressure transmitted through the water sheet was roughly constant regardless of standoff distance and explosive strength.

“…Experiments and numerical simulations have been conducted to investigate the suitability of water as a barrier material (Cheng, Hung, & Chong, 2005;Homae, Wakabayashi, Matsumura, & Nakayama, 2006;Keenan & Wager, 1992;Shin, Lee, Lam, & Yeo, 1998). These studies demonstrated that the maximum peak pressure and impulse were significantly reduced by surrounding the high explosive with a barrier.…”

“…had significant effects on mitigating blast wave, especially for the case that water was stored close to the explosive. The principle of water in mitigating blast wave is that the high pressure shock wave produced by detonation aerosolizes the water placed close to the explosive and causes both a phase change of water and the redistribution of internal and kinetic energy over the detonation gases, blast wave and barrier material [8]. The aforementioned research on water mitigation effects on blast wave was based on the scenario that water directly interacts with blast wave.…”
