摘要:
为了辨析氢气(H2)的化学作用对异辛烷(iC8H18)燃烧主要产物和中间产物的影响,该文对添加氢气的异辛烷层流预混火焰进行化学反应动力学分析。结果表明,随着H2添加量的增大,一氧化碳(CO)、二氧化碳(CO2)和甲醛(CH2O)等主要产物,H、O、OH自由基以及甲醛中间产物的摩尔分数减少。H2的化学作用促进上述产物的生成,而H2的热作用和稀释作用使这些产物的浓度降低并占主导地位。H2的化学作用对乙炔(C2H2)的抑制作用随着H2添加量的增大呈非线性变化。
Abstract:
The chemical effects of hydrogen addition on laminar premixed iso-octane flames at the atmospheric pressure are studied by the detailed kinetic analysis.The chemical effects of hydrogen addition on the mole fractions of major species,intermediates and free radicals are distinguished clearly from the dilution effects and the thermal effects.The results show that the mole fractions of CO,CO2,CH2O species,H,O,OH radicals and the CH2O intermediates decrease with the H2 addition increasing.The chemical effects of hydrogen addition promote the productions of these species and radicals,and the dilution effects and the thermal effects of H2 on diminishing the concentration of these species and radicals are dominant.The chemical effects of H2 on C2H2 mole fractions vary non-linearly with the increasing of hydrogen addition.
