| 摘 要： | 对微小通道内氢气／空气预混火焰进行了数值模拟。通过对比考虑壁面反应和不考虑壁面反应的微通道内燃烧特性的差异，考察了壁面反应对微通道内燃烧状况的影响，揭示了壁面附近自由基行为和壁面反应、气相反应的相互关系，并探讨了不同尺度下壁面反应效应的程度。结果表明，壁面反应改变了微火焰结构，近壁面附近的自由基被吸附，在径向上出现了明...

| Abstract: | A numerical simulation of hydrogen/air premixed flames in micro-channels is performed. To gain a understanding of flame-radical-wall interaction on millimeter and submillimeter scale combustion, the effects of surface reactions including 5 adsorption reactions and 7 desorption reactions on hydrogen/air premixed flames are investigated by comparing differences of flame structures with surface reactions or not.The results shows that surface reactions have a significant influence on flame structures and radica... |
