摘要:
 针对甲烷/空气预混气体层流平面火焰,利用LIF 技术,采用双向光路法对燃烧过程中所产生的OH 基
进行了测量,得到其一维绝对浓度值及其空间分布,并分析其产生的动力学因素.结果表明,当量比为0.8~1.0
范围内,OH 基绝对浓度差别不大;当量比在1.1~1.3 的范围内,OH 基的绝对浓度呈下降趋势,一方面由于OH
基消耗反应OH+CH4→CH3+H2O,随着CH4 量的增大,OH 基的消耗速度增加,另一方面OH 基生成反应
CH3+O2→OH+CH2O,虽然CH3不断生成,但由于O2的流量逐渐减小,所以OH 基的生成率逐渐下降,二者
共同作用导致OH 基绝对浓度随着当量比的增大而减小.实验所测OH 基绝对浓度值与Versluis 等测得的OH 基
绝对浓度的数量级相差不大.
Abstract:
 Aiming at the structure of CH4/Air premixed laminar flat flame(LIF) and bidirectional optical path
were used to measure the OH radicals formed during the combustion process,the absolute concentration and distribution
regions of OH radicals were obtained,and the kinetics of the reaction were analyzed.The result shows
that when the equivalence ratio ranges from 0.8 to1.0,the concentration of OH is almost the same;when the
equivalence ratio ranges from 1.1 to 1.3,the concentration shows a decreasing trend.One reason is the OH consumption
reaction OH+CH4→CH3+H2O.With the increase of CH4 concentration,the OH consumption velocity
increased. The other reason is the OH formation reaction CH3+O2→OH+CH2O.Although CH3 was generated
continuously,the OH formation rate decreased gradually due to gradual decrease of O2 mass flow.For both reasons,
the OH centration decreased with the increase of equivalence ratio.The difference between the OH absolute
concentration obtained in our experiments and that by Versluis was only an order of magnitude.
