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.
