Study of Explosive Characteristics of Natural Gas in Pipelines
A two—dimensional model of natural gas explosion characteristics for premixed combustible mixture was established.In the model,considering control action imposed on an explosion from turbulence and chemical reaction kinetics,a turbulent combustion model coupled with reduced mechanism of detailed chemical reaction kinetics was set up.The governing equations of flow and the reaction equations were solved simultaneously (i.e.,coupled together) by the finite volume method (FVM).Explosive characteristics and rules for natural gas in pipelines were studied by numerical simulation.The conclusions made in the paper laid a foundation for further studies of the flammable gas explosion process and the prevention of an explosion disaster.
