用 Fortran程序分析甲烷的燃烧问题(英文)

Analysis of CH_4 Combustion Problem with Fortran Program

根据甲烷燃烧过程的热力学性质 ,用 Fortran程序研究了在绝热反应器中甲烷燃烧过程中的有关问题 .分析了在绝热反应器中甲烷用量恒定时 ,不同量的空气对燃烧温度、化学组成、流动能及热传递能的影响 .实验表明 ,燃烧过程中使用过量的空气且没有离解反应发生时 ,其中有 2种状态具有相同的组成 ,同时 x N2 和x O2 也会增大 ;当有离解作用存在时 。

Based on the thermodynamic properties of combustion process,methane combustion process in the adiabatic combustor was analysed by Fortran program.When the quantity of methane was definite,the effect of differentamount of air used on the temperature,chemical composition,flow energy,heattransfer energy and irreversibility of the combustion process were investigated.It was found that two states had the same compositions,and x N2 and x O2 in these states would increase when the amount of air was over supplied into the combustion and no dissociation.Under the condition of dissociation the irreversibility waseasily to occur.
