与传统的明焰燃烧相比，多孔材料在空隙内燃烧在性能和排放方面的优势促使许多研究了解和利用潜在的多孔结构拓扑和所需的系统级特性之间的联系。本研究探讨了几何功能化复合陶瓷结构实现新型多孔介质燃烧器设计理念以提高性能的可行性和性能。利用三周期最小表面合成了光滑梯度多孔结构，并通过基于光刻的陶瓷制造工艺进行了制造。在这些结构上进行了实验，以表征三种不同孔尺度拓扑结构的火焰稳定性、轴向温度分布和压降。这些测量结果得到了来自一维体积平均模型的计算预测的称赞。利用X射线计算机层析成像验证了结构的相关几何性质，并对燃烧后的材料进行了检查。这项工作展示了第一个平滑分级燃烧器，利用添加剂制造方面的最新进步来设计、制造和测试传统泡沫陶瓷制造技术无法达到的燃烧器概念的性能。
The advantages in performance and emissions from combustion within the voids of a porous material, as compared to those of conventional open-flame combustion, have motivated numerous studies to understand and harness the connection between the underlying porous structure topology and the desired system-level properties. The current study examines the feasibility and performance of additively manufactured complex ceramic structures with geometric functionalization to actualize novel porous media burner design concepts for enhanced performance. Smoothly graded porous structures are synthesized using triply periodic minimal surfaces and manufactured via lithography-based ceramic manufacturing. Experiments are performed on these structures to characterize flame stability, axial temperature profiles, and pressure drop for three different pore-scale topologies. These measurements are complimented by computational predictions from one-dimensional volume-averaged models. X-ray computed tomography was used to verify relevant geometric properties of the structures, as well as to examine the material after combustion. This work demonstrates the first smoothly graded burner, leveraging recent advancements in additive manufacturing to design, fabricate, and test the performance of burner concepts unattainable by traditional ceramic foam manufacturing techniques.
