Abstract

To research the distribution of unconfined gas cloud explosion overpressure field and impulse field, build domed finite element model of combustible gas, use computational fluid dynamics, and get the numerical simulation of the methane-air gas explosion. The numerical calculation of overpressure fits the experimental result. The impulse field depends on the overpressure and time; the impulse at the gas cloud boundary is maximum. And the formulas of overpressure and impulse were calculated by data fitting.
