expression/equation for simple calculation of H2 combustion rate? |

一般来说,如果不是在火焰里面,h2跟o2只有两条反应路径吧
h2+o2=oh+oh
h2+o2=ho2+h
这两个速率在很多数据库都能查到,NIST的免费

The project I am on need to figure out how fast O2 dissipate in H2 ambient at ~900 C.
All that I am looking for is an estimation of the time scale of O2
dissipation. Could you please help? |

发帖数: 270 | 6 你可以这样试一下。第一个链接里面可以下载mechanism跟thermal properties，这个
是CHEMKIN的input file，你还需要知道的是起始和最后的T,P,起始浓度，equivalence
ratio,reaction time,反应器类型.这样就可以
run CHEMKIN了，CHEMKIN的输出文件有你给的反应条件下各个组分浓度随时间的变化，
这个【应该是你需要的
这样应该是很准确的。
