微燃烧室内甲烷燃烧的数值模拟

摘要

建立了微燃烧室中的湍流燃烧模型,采用FLUENT软件对微燃烧室中甲烷/氧气的燃烧特性进行了数值模拟,研究了甲烷/氧气的当量比为1时不同流量对微燃烧室内燃烧的影响.计算结果表明,随着混合气流量的增加,燃烧室内的温度升高,甲烷的质量浓度下降.%FLUENT software is used to simulate the methane-oxygen combustion in a microcombustor. When the equivalence ratio of methane/oxygen is 1, the infulence of the volume flow to the combustion in the micro-combustor is researched. The computation results show that when the volume flow increases, the temperature increases in the combustor and the CH4 concentration decreases.
