kinetic data for methane air global reaction
 

Hi All,

I am using the finite rate chemsitry model in fluent. The pre-defined values in fluent are for a stoichiometric methane air reaction. However, I have a lean methane air mixture and for this mixture, i will like to determine what the frequency factor and the activation energy. Better still, i there a way i can determine those values (i mean activation energy and pre-exponential factor) for a given equivalence ratio?

Counting on your assistance.
