摘　　要：应用Fluent模拟防爆格栅火焰淬熄情况,并对结构参数和火焰淬熄之间的关系进行定性分析。结果表明,扩张腔直径和平板厚度对火焰淬熄效果有一定的影响,扩张腔角度和长度变化对火焰淬熄效果基本无影响,为防爆格栅的设计及应用提供参考。CFD software Fluent was applied to simulate the flame quenching of fire attesters, and the relation was analyzed between structure parameters and flame quenching. The analysis results show .that diameter of bumper - separator and thicknesses of parallel plate have some influence on flame quenching, angle and length of bumper - separator have no influence on flame quenching. This article will provide reference for design and application of fire arresters.
