摘要
燃气与固体构架之间强烈的换热,使多孔介质内的燃烧与自由流中的燃烧有很大不同．模拟了甲烷／空气预混气在多孔介质内的一维层流燃烧过程,详细考察了多孔介质构架中的辐射换热和气固之间对流换热,并使用了详细化学反应机理,其计算结果能够较好地预测多孔介质内的各种燃烧特性．
Premixed combustion in the porous medium substantiaUy differs from combustion in the free space because of strong heat transfer between the gas mixture and the porous medium. The premixed combustion of CH4/Air mixture in a porous medium is numerically simulated with a laminar combustion model. Radiative heat transfer in the solid and convective heat transfer between the gas and the solid is specially studied. A smaller detailed reaction mechanism is also used and the results can show good prediction for many combustion phenomena.
