Abstract
Attenuations of shocked gas flow propagating through porous materials, are investigated experimentally and numerically. Process of shock attenuation occurs when shocked gas flow travel through porous materials such as polyurethane foam or wire mesh. Foams used have high-porosities ϕg= 0.951 ∼ 0.977 and low densities ϱc=27.6 ∼ 55.8 kg/m3, while the wire mesh has low-porosity ϕg=0.36. Shock tube experiments are conducted by using a shock tube with 50 mm in diameter and 6.4m in length. Pressures behind the fixed foam were decreased from the incident shocked pressure, which implies that the shock wave was well degenerated, and in some cases into compression waves. Pressure attenuation factor Ka caused by the presence of foam was estimated to be about 60 ∼ 75 % of the value in the absence of foam value.
