yorelchr is on a distinguished road
Hi everyone,

I've tried to find some answers on the forum and the net, but no way.
I want to add two equations in an existing chemkin file. First I would like to know if it is ok or if it's better to add these 2 equations "manually" in Fluent.

I would also like to find the values I have to insert (pre-exp factor, temp coeff, activation energy). I haven't studied any chemistry so I learn a little more everyday at work: when we have the activation energy in J/kgmol as it is the case in Fluent, it's ok for tranforming in cal/mol, but how can we transform the pre-exponential factor? is it possible or one must find the values on tables? where could I find these values?
my 2 equations are :

and another set of 2 equations :

Thank you for any help. If you have any link that could explain me how all this work, I would be pleased :-)
