Hi all,

In the chemistrymodel library, there is a value called Treact. How does openfoam calculate this value or does it read the value from somewhere.?

In chemistryModel/chemistryModel/StandardChemistryModel/StandardChemistryModel.C

Treact_
    (
        BasicChemistryModel<ReactionThermo>::template lookupOrDefault<scalar>
        (
            "Treact",
            0
        )
    )

This is not in the previous openfoam versions.

Thanks,
Senthil.

Often an explanation is given in the .H files. In this case:


StandardChemistryModel.H

//- Temperature below which the reaction rates are assumed 0
        scalar Treact_;

But also online search gives the result very fast: "treact openfoam" was enough .


So in your version 6 "Treact" is looked up somewhere or if it is not defined at the lookup destination it is set to zero. So no reaction for temps below "Treact" and if not defined, this value is set to zero.


Edit: I did not find a tut with it but it should just be possible to put the value into 'chemistryProperties'-dict in constant. For example:

 
Treact    273.15;
