Summary0003085: Enthalpy coefficient a_ wrong for C3H6O.C
DescriptionHi all,

just came across a thread on CFD-Online about an issue of the C3H6O enthalpy calculation specified here https://cpp.openfoam.org/v6/C3H6O_8C_source.html

I sum up. The calculation of the enthalpy based on the NSRDSfunc0 (https://cpp.openfoam.org/v6/NSRDSfunc0_8H_source.html#l00103), lead to a value that is in the range of Xe6. However, other species such as C4H10O have a range of X e-6 (power sign); https://cpp.openfoam.org/v6/C4H10O_8C_source.html.
Comparing both (and others) lead to the assumption, that the coefficient a_ has a wrong sign.

However, I have no access to the database used here, and thus, I cannot prove my statement.

I don't have access to the NSRDS database either. If someone can provide the correct coefficients I would be happy to correct the code otherwise the best I could do would be to remove this specie.

I was in contact with TU Munich and I will get an access to the main library. They have the book there so I will check it after I am close to Munich.
