Diffusion Effect of Blast Pressure in Porous Complex Media
説明
3 ; and sand layer with low- porosities g = 0.435 and high densities c = 1500 kg/m 3 . Peak overpressures in polyurethane foam and sand layer decrease quickly than that in air, as the blast wave is degenerated into compression waves due to its interaction with three-dimensional porosity distribution. Pres- sure attenuation caused in present complex media are in between 60 to 95 % of the peak overpressure value in air.
