The Simulation Numerical Of Indoor Gas Leakage Diffusion And Combustion Explosion

Because of the advantages of high efficiency, economy and clean, gas fuel becomesfavourites. However, if gas leaks in the indoor space, it is hard to spread, and easy to pile upwhich more likely causes fire and explosion accidents. And there is no product protectspeople from fire and explosion in the household, and people lack relative safety knowledge,once the accident happens the whole Community will faces serious damage. So the study ofthe explosion hazardous area distribution after gas leakage and the characteristics of theexplosion and combustion is very importantThis paper writes about Combustible gas leakage accident in house kitchen, and itbriefly introduces the situation and theoretical analysis of indoor gas leakage diffusion inrecent years, and using CFD numerical simulation software Fluent14.0to simulate gasleakage diffusion process under different influence factors, getting concentration distributionof combustible gas at different temporal and spatial, research and analysis the indoor gasleakage diffusion and the migration of combustion gas explosion hazardous area to a certaindegree; and by using the TNT equivalent method to analysis the risk.And on this basis, usingAutoReaGas to simulate indoor gas leak explosion and combustion, and briefly analysis therisk consequences of the explosion, and compare to results of the TNT equivalent method,making prediction that damage and concentration of Combustion and explosion accident afterindoor gas leakage.Finally, this paper summarizes the present shortage of gas leakage diffusion and thefuture development of prospects. Based on the analysis that the danger of combustion gasexplosion, putting forward some measures, which can further reduce the damaging effects ofCombustion gas explosion accident.
