I'm using hydrogen air reaction mechanism for my shock tube simulation, the mechanism includes 11 species and 23 reaction. Third body efficiencies is included in this case.
I'm wondering what efficiency factor should I specified for each species, because there are different efficiency factor for some species which specified in the chemkin input file. The chemkin input file is attached.
For example, H2O has efficiency factor of 18.6 for the reaction H + O2 + M <=> HO2 + M and efficiency factor of 5 for the reaction H + OH + M <=> H2O + M.
So for the third body efficiency input box, should I choose 18.6 or 5 for H2O?
Thanks for helping me out!

Just read the mechanism and the parameters are parsed directly.

Please use a recent Ansys Fluent Version

I'm usinig the Uni PC, unfortunately version 19.2 is my only option.
So, do I just import the mechanism, enable the third body efficiency and leave the default efficiency parameters?

It will be enabled automatically. Yes 19.2 is old and If I remember there were some small issues which has been fixed might be important for your case here. Try to use a newer version.
