摘　　要：Computational fluid dynamics （CFD） combined with detailed chemical kinetics was employed to model the filtration combustion of a mixture of methane/air in a packed bed of uniform 3 mm diameter alumina spherical particles. The standard k-ε turbulence model and a methane oxidation mechanism with 23 species and 39 elemental reactions were used. Various equivalence ratios （1.47, 1.88, 2.12 and 2.35） were studied. The numerical results showed good agreement with the experimental data. For ultra-rich mixtures, the combustion temperature exceeds the adiabatic value by hundreds of centigrade degrees. Syngas （hydrogen and carbon monoxide） can be obtained up to a mole fraction of 23%. The numerical results also showed that the combination of CFD with detailed chemical kinetics gives good performance for modeling the pseudo-homogeneous flames of methane in porous media.与详细化学动力学相结合的计算流体力学(CFD ) 被采用在制服 3 公里直径氧化铝的一张填充床为甲烷 / 空气的混合物的过滤燃烧建模球形的粒子。有 23 种类和 39 元素的反应的标准κ - 骚乱模型和甲烷氧化机制被使用。各种各样的等价比率(1.47， 1.88， 2.12 和 2.35 ) 被学习。数字结果与试验数据显示出好同意。为极端富人的混合物，燃烧温度由几百百分温度超过断热的价值。Syngas (氢和一氧化碳) 能被获得直到 23% 的一个摩尔份数。数字结果也证明有详细化学动力学的 CFD 的联合为在多孔的媒介为甲烷的伪 homogeneous 火焰建模给好性能。
