Numerical Simulation of Explosive Characteristics and Rules of Flammable Gas in Closed Pressure Pipe
The turbulent combustion model of explosion in Closed Pressure Pipe was presented on the basis of the single-step chemistry reaction. The RNG (renormalization group) k-ε model was adopted. According to the high rate of reaction and the turbulence phenomena, EBU (eddy broken up)-Arrehnius combustion model was applied. 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 in two-dimension closed pressure pipe was studied by numerical simulation. The results that agreed with experiment date laid a foundation on the further studies on flammable gas explosion process and the prevention of the explosion disaster.
