Update on how to implement the temperature equation in interPhaseChangeFoam

JD_PM · June 25, 2022, 09:57

Yesterday I posted about the issues I was having while implementing a simple version of the temperature equation in interPhaseChangeFoam (Implementing the temperature equation in interPhaseChangeFoam (OpenFOAM 8 version)) and advanced a bit.

All I did was changing the name of the original solver to interPhaseChangeThermalFoam, change the name of the file phaseChangetwoPhaseMixture to twoPhaseMixtureThermo and modifying the following files

interPhaseChangeThermalFoam.C

I get the following error when I compile the solver

So it seems that the problem is with the temperature equation file.

Any feedback is appreciated.

I changed the TEqn.H file as follows

Code:

solve
(
	fvm::ddt(T) + fvm::div(phi,T) == fvm::laplacian(DT, T)
);

I compiled the solver and it yielded a new error:

I decided to run it anyway and see if it worked.

I used a tutorial case (cavitatingBullet) and included T boundary condition

        value           $internalField;
    }

    walls
    {
        type            symmetry;
    }

    bullet

When I run it I get the following error

Code:

[1] --> FOAM FATAL IO ERROR:

Any feedback is appreciated.

The mistake was in the createFields file. Temperature is of course a scalar field.

Code:

//scalar field for the temperature
Info<< "Reading field T\n" << endl;
volScalarField T
(
    IOobject
    (
        "T",
        runTime.timeName(),
        mesh,
        IOobject::MUST_READ, // Must read T from the latest time directory
        IOobject::AUTO_WRITE // Data will be written according to controlDict
    ),
    mesh
);

Now it compiles OK.

Hi JD_PM,

Thanks for these useful information. I just wanted to know: Are you able to define temperatures for the different phases with this implementation? For example, say your phases are air and water. Are you able to define T.air and T.water initial conditions in the 0 folder of your case files?

Thanks,
Prithvi

You can do it by using the thermo libraries for example. But then you have to rewrite your twoPhaseMixture file otherwise you will have redundancies.

Hi überschwupper,

I have copied a library named "twoPhaseMixtureThermo" from compressibleInterFoam to my custom interPhaseChangeFoam directory. Is this what you are talking about? I'm using this because I had observed in the compressibleInterFoam tutorial cases that each phase has it's own T.phase file.

Right now, I have copied this library and I am removing the thermodynamic properties from the libraries that I do not need. Am I going in the right direction?
