摘要
针对细水雾作用下CH_4/空气燃烧反应机理,将细水雾作为拟气体物质引入机理中。采用对冲火焰模型,对比和评价了细水雾作用下的不同总包机理,并提出改进方法。改进后的总包机理模型JL2X能够更好地预测出发生熄火时细水雾质量分数区间、H_2O体积分数分布和CO体积分数分布。
The water mist was considered as a quasi gaseous sub- stance then was introduced into CH4/air combustion reaction mechanisms. The counterflow flame model was used to evaluate the different CH4/Air global combustion mechanisms under the influence of water mist, and the improvement methods were proposed. The modified CH4/Air global combustion mecha- nisms JL2X can predict water mist mass fraction range of flame out, H20 volume fraction distribution and CO volume fraction distribution more accurately.
