Porous media combustion (PMC) is an active field of research with a number of potential advantages over free-flame combustors. A key contributor to these phenomena is the interphase heat exchange and heat recirculation from the products upstream to the reactants. In this paper, we present a network model that captures the conjugate heat transfer in pore-resolved 2D simulations of PMC. A series of simulations are presented with varying solid conduction and inlet velocity to isolate the role of conjugate heat transfer on the salient features of the burner, including flame stability, axial temperature profiles, and flame structure. We show that both the flame stabilization and the propagation behavior are strongly related to the conjugate heat transfer, and the flame stability regime is shifted to higher velocities as the conductivity of the solid material is increased.

多孔介质燃烧（PMC）是一个活跃的研究领域，与自由火焰燃烧器相比具有许多潜在的优势。这些现象的关键因素是相间的热交换和从上游产物到反应物的热再循环。在本文中，我们提出了一个网络模型，该模型捕获了PMC的孔分辨2D模拟中的共轭传热。提出了一系列具有不同固体传导和入口速度的模拟，以隔离共轭传热对燃烧器显着特征的作用，包括火焰稳定性，轴向温度分布和火焰结构。我们证明火焰稳定和传播行为都与共轭传热密切相关，
