| 摘 要： | 多孔介质内气体过滤燃烧不同于自由流中燃烧，燃气与多孔介质强烈换热．热波波速和燃烧波波速是燃烧过程的特征参数．以惰性堆积床内的甲烷／空气的低速过滤燃烧为例，提出一维解析模型，用摄动理论推导出燃烧波波速，用直接求解方法和格林函数方法给出充分发展后的和瞬态的燃烧温度分布，并进行计算验证．

| Abstract: | Gas filtration combustion in porous media differs substantially from the combustion with free flame.A one-dimensional model is proposed,and a perturbation theory is used for the combustion front velocity analysis of the methane-air premixed combustion in an inert packed bed.The temperature distribution is predicted for either fully-developed or transient combustion state,based on direct solution and Green's function method.Finally,computational experiments are given and the results are satisfactory. |
