Simulation Analysis of Indoor Gas Explosion Damage

The influence factors and process of indoor gas explosion are studied with AutoReaGas explosion simula-tor. The result shows that venting pressure has great influence on the indoor gas explosion damage. The higher the venting pressure is, the more serious the hazard consequence will be. The ignition location has also evident ef-fect on the gas explosion damage. The explosion static overpressure would not cause major injury to person and se-rious damage to structure in the case of low venting pressure (lower than 2 kPa). The high temperature combus-tion after the explosion is the major factor to person injury in indoor gas explosion accidents.
