多孔介质(泡沫陶瓷)预混燃烧是一项新颖、独特的燃烧技术。本文将分形理论应用到多孔介质压降模型中,建立了分形模型。并且求解了多孔介质特性参数:粘性阻力系数与内部阻力系数。并针对实验条件进行燃烧数值模拟研究。通过和实验数据对比,发现数值模拟和实验能较好相符合,说明此模型具有一定的可靠性。
Combustion in porous ceramics is a novel and unique technique.This paper has taken the Fractal Geometry Theory to establish the math model of the pressure drop of the porous media and has solved its identified parameters: viscous resistance, intertial resistance. We did the study on numerical simulation about Combustion in porous ceramics based on the experiment condition. We can happily find that the results of numerical simulation can accord with the experiment dates,which testifies the model credibility.
