  • In order to explore the influence of CO2 and porous materials on methane explosion characteristics, the 100 mm×100 mm×1000 mm explosion pipeline was independently designed. The influence of porosity of different porous materials and CO2 injection pressure on methane explosion flame structure, flame propagation velocity and explosion overpressure were examined. The results show that: the porous material has two opposite effects on flame wave attenuation and promotion. When the porosity of the porous material is 10 and 20 PPI, it fails to resist the explosion, but when the porosity is 40 PPI, the explosion resistance is evident. CO2 jet pressure has a certain effect on explosion resistance. When the porous material is 10 and 20 PPI, the peak flame velocity decreases gradually with an increase in CO2 jet pressure, the maximum attenuation rate is 13.64%, and the maximum attenuation rate of the peak explosion overpressure is 52.83%. According to the variations of flame velocity and pressure, the porosity of the porous material is 40 PPI, and the CO2 jet pressure is 0.4 MPa, the explosion suppression effect is the optimal.
