using Chemkin
 

Hi Foamers.
I was trying to use Chemkin to calculate chemistry based on mass fraction of species from OpenFOAM. I was going to use Jones and Lindstedt's 4 step mechanism for CH4 combustion. The version of chemkin interpreter I use is 1.4, and having some difficulties with entering the forward and backward reaction orders. Also, the pre-exponential and activation energy are supposed to be entered in cm-mole-s-K and cal/mole respectively. However I am not sure about the unit of these constants in the mechanism in the paper (Jones and Lindstedt 1988). Can someone advise me how to enter forward and backward reaction order in the chemkin interpreter V1.4, and convert the paper's pre-exponential and activation energy perspective to chemkin's units?
Thanks.
