Summary0003954: Contribution for PLOG Chemistry - revisited
DescriptionAs mentioned by other reports, the new reaction format from chemkin with pressure dependent reaction rates (PLOG) is not usable in OpenFOAM.

Therefore, I modified the chemkinReader to be able to read those reaction types and added a pressureDependentArrheniusReactionRate similar to the PLOG reaction in chemkin. The current implementation is in OpenFOAM-9.

The interpolation is now inline with the reaction rate in cantera (https://cantera.org/documentation/docs-2.4/doxygen/html/dd/d89/classCantera_1_1Plog.html).

The implementation was used to predict the ignition delay times with chemFoam and the results compared to results from cantera (see attached plots). Additionally, the model was tested with the SandiaD_LTS tutorial case.
TagsNo tags attached.

Class
    Foam::pressureDependentArrheniusReactionRate

Description
    Arrhenius pressure dependent reaction rate analog to PLOG in Chemkin.
    Where the parameters are interpolated lineraly between the logarithmic
    pressures (see e.g. cantera)

    The parameters in the reaction file are stored as following:

    un-named-reaction
    {
        type       ...PressureDependentArrhenius
        reaction   "A + B = C + D";
        A           table (
                    (4   -17)
                    (10  7)
                    (18  75)
        );
        beta        table (
                    (4    2)
                    (10  -5)
                    (18  -6)
        );
        Ta          table (
                    (4   4400)
                    (10  12000)
                    (18  14000)
        );
    }

    the pressure is stored as log(p)
    also the values for A are stored as log(A)
    to make use of the available interpolation Table in OpenFOAM

Apologies for the silence on this one. There's no good answer here, so I'm afraid this just got delayed. Realistically, no, we are not able to accept this contribution for a number of reasons.

- It is still not clear to me that your implementation matches the Cantera documentation reference. The reference interpolates two Arrhenius rate expressions using the log of the pressure. Your implementation interpolates the *coefficients* of the Arrhenius rate expressions using the log of the pressure. These operations are unlikely to be equivalent.

- Your implementation is for version 9. The reaction interface has changed since then.

- There is no test case, either of the reaction itself or of the chemkin reader.

- What happens if the simulation pressure exceeds the range of the table?

- What happens if your coefficient tables do not have the same pressure ranges?

- It looks like a user is supposed to enter coefficients as a table for which the X-axis is the log of the pressure. That's unintuitive. The user inputs should relate to the pressure itself.

- I think in general, a pressure-dependent rate such as this should modify/interpolate a general sub-reaction rate type; i.e., not be hard coded to Arrhenius.

Resolving all of these issues will take time on the part of the core OpenFOAM developers, and that has a cost associated with it. This functionality's maintenance thereafter will also have a cost associated with it. If you want this functionality released in OpenFOAM you need to find an organisation that is willing to pay for both of these things.

Closed pending funding.
