Experimental Study and Attenuation Analysis of Methane Explosion Propagation in Porous Metallic Materials

摘要：

In order to explore the effects of porous metallic materials on methane explosion propagation, the propagation laws of flame and shock wave in porous metallic materials installed along duct were experimentally investigated and theoretically analyzed in this paper, according to reaction mechanism of gas explosion and characters of porous metallic materials. It shows that the porous metallic material can suppress the propagation and the suppression effect is related with the layers, length and porosity etc. The attenuation of methane explosion propagation in porous metallic material is analyzed from reducing energy, eliminating reflection wave and breaking reaction chain. The attenuation models, which are mass sink model, planar shock wave attenuation model and incline shock wave attenuation model, are established. The attenuation of methane explosion propagation in porous metal material is the result of multi-effects, which are mass sink effect, refection wave elimination, energy losing and reaction chain breaking. The result can offer technology help and theoretic base for suppression technology of gas explosion.
