The Quenching Characteristics of Gas Deflagration Flame in Narrow Channel

Abstract:

In order to obtain fire retardant mechanism of gas deflagration flame in narrow channel, a numerical simulation adopting PISO algorithm and self-adapted grids was presented based on the single-step irreversible chemical reaction and the combustion model of EBU-Arrhenius. The numerical dates are well compatible with experimental results and indicate that the initial flame velocity and gap of channel are directly responsible for the quenching distance. And the smaller the flame velocity or gap of channel, the shorter the quenching distance, which means simpler to quench gas deflagration flame.
