Arrhenius coefficients for methane air single step combustion
 

Hi everyone.

I am trying to simulate methane/air turbulent combustion in openFoam. I want to use one step reaction (CH4+2O2=CO2+2H2O) but I am very new in combustion and don't know which Arrhenius coefficients I must use in my case. I looked for in Articles and found different coefficients.

1.can somebody help and give me the true coefficients ?

2.If I want to use another fuel and reaction how can I found the new coefficients ?

thanks.:)
