中文摘要：
通过一维数值模拟研究了预混气体在两层多孔介质燃烧器内的燃烧特性,着重研究两层多孔介质燃烧器中的超绝热燃烧和火焰的稳定区域。结果表明,预混气体在两层多孔介质内可以发生一定程度的超绝热燃烧,贫燃极限可以扩展到0.45。两层多孔介质能够在较宽的流速范围内将火焰稳定在它的交界面上。数值预测的最小和最大火焰传播速度与实验取得了相同的趋势,其火焰传播速度至少是自由空间中的3倍。
英文摘要：
A one-dimensional numerical simulation was performed of the combustion characteristics of a premixed gas in a dual-layer porous medium burner.The super-adiabatic combustion and stable flame zone in the burner under discussion were mainly studied.The research results show that the premixed gas can produce super-adiabatic combustion to a certain extent inside the dual-layer porous medium and the lean combustion limits can be extended to 0.45.The dual-layer porous medium can stabilize the flame at the interfac...
