| 摘 要： | 采用自适应化学理论AdapChem的方法对两种CH4/空气部分预混、非预混火焰的燃烧过程开展了数值模拟工作.计算得到了两种燃烧工况下,几种重要的主量成分、非主量成分的浓度值;同时对反应放热和HCO之间的潜在关系进行了分析.通过对两种工况下模拟结果的比较,AdapChem方法合理预报了甲烷预混和非预混燃烧过程的各种物理化学特性,并达到了节约计算时间的目的.

| Abstract: | In this paper,atmospheric pressure,over-ventilated,axisymmetric,coflowing,two laminar methane flames are simulated using Adaptive Chemistry.The computational results including reacting model structures,temperature distributions,mole fractions of CO_2,H_2O,OH,CH and CPU times for each iteration step obtained for the two flames are discussed,showing that adaptive chemistry can simulate properly all features of the two flames chemical structure with high efficiency. |
