| 摘 要： | 考察了水蒸气的加入对液体燃料高温分解时碳黑形成的影响。采用直接测量碳黑沉积质量的方法,得出水蒸气能够抑制液体燃料中碳黑颗粒形成的结论,并总结出碳黑在图壁表面沉积的一些规律特征。在进行实验的同时,采用Fluent软件,模拟了两种实验工况下炉内的碳黑颗粒浓度场,证实了实验结论。最后,给出了计算公式,选取合适的待定参数,则计算结果与实验结果符合很好。

| Abstract: | The influence of water vapor injection on soot formation during liquid fuel pyrolysis is investigated. By directly measuring the mass of soot deposited on a solid wall surface it was found that water vapor can suppress the formation of soot particles. Some characteristics concerning the deposition of soot on a solid wall surface were ascertained. Meanwhile, by using software "Fluent" the soot particle concentration field was simulated under two kinds of experimental operating conditions, making it possible to confirm the relevant experimental conclusions. Finally, a calculation formula is given. When suitable parameters to be determined are selected, the results of calculation agree quite well with those of tests. |
