XiFoam_JANAF thermodynamics coefficients

sharifi · October 18, 2014, 13:43

Hello,

regarding XiFoam I have some question. It would be very nice if somebody can help me.

1)I'm wondering how you can calculate the JANAF coefficients for Methan or other fuels. There should be a book or sth, am I right?!!

2)since I'm using OF1.7 I'm wondering, why there is "fuel" , "oxidant" and in addition "reactants"?

best wishes,
Jim

Hi Jim,
Have you find anything on Janaf coefficients ? I'm also interested in... (And according to the number of view, I think that's interesting many people)

You can get Janaf coefficients for a lot of common simple chemicals off the internet.
e.g., http://combustion.berkeley.edu/gri_m...ies/thermo.dat
or better yet from Burcat

Thank you Andrew for your link.
Do you know if it's possible to use the Janaf model with temperature under 200K ?
Or Janaf scale coefficient are always starting over 200K ?
