摘要
The leakage and explosion accident of the pipeline of LNG regulator station were investigated in the present paper.Numerical simulation of gas leakage and explosion process was made with Fluent and AutoReaGas software.Some monitoring sites and monitoring surfaces were set to obtain the concentration distribution,gas explosion overpressure,speed and explosive detonation temperature of methane at different times.Reasons and rules related to the changes of gas explosion overpressure can help us to research gas diffusion and explosion laws.Conclusions of this study can provide reference for the regulator stations and other potentially explosive confined spaces' safety design.The aim is to strength the overall security of natural gas pipeline system,and to control the consequence of explosion accidents through reducing casualties and property losses.
