Hi foamers,
I'm trying to use Janaf model to run reactingFoam.
I've seen that there is 2 Janaf model.
Apparently, I have the old one, seeing my type of definition with only 7 coefficients (high and low) and a Tlow, a Thigh then a Tcommon.
My scale temperature is very low 100K-300K (so apparently again that's feeting for the old Janaf model) but I had difficulties to find correct Janaf coefficients (with so low temperature, under 200K).
But for now it's ok, I've find a website that seems great and I would recommend it for everyone:
http://kinetics.nist.gov/janaf/

The thing is, I'm completely lost concerning the units... I don't know what are the one used in OpenFOAM... So I'm completely lost and I don't know the correspondence between the website coefficient, and the OpenfFOAM coefficient.

(I tried a few combination on the Cp0 using R and rho to have an idea, but it never matched with the OpenFOAM tutorial...)

Could anyone helped me with an exemple ? I've put a screenshot of CH4 (because that's one of the element that I use)

Than you,
Adrien

In fact I'm stupid... this is the values calculated with the Janaf coefficient, that's why it couldn't matched. But I'm still looking for the units used in the old Janaf model....
