摘要
天然气在惰性多孔介质内的预混燃烧是一个包含燃烧、辐射、对流及导热的复杂过程,从数学模拟的角度,比较了几种不同的甲烷-空气化学反应模型,研究了多孔介质内辐射传递方程的不同求解方法,并且分析了多孔介质的导热系数、对流换热系数等对燃烧器性能的影响。
Premixed combustion of natural gas within inert porous media is a complicated process including combustion, radiant heat transfer, convective heat transfer and conductive heat transfer. This paper compares several different models for methane air combustion, studies different methods for solving the RTE of porous media, and analyzes the relations between thermal conductivity, convective heat transfer coefficient and the performance of porous media burners.
