gapGasTimeTabulated

Description

Model for time-dependent gap gas composition, and pressure when the data is provided from external source (for instance, other fuel performance codes). The time-dependent lists of mass fractions and gas pressures are provided within the gapGasOptions subdictionary within the solverDict file.

A 'gapGas' input file as for the case of gapFRAPCON is always needed with the snapshot of gap compositions and pressure at time t = 0 or time of restart.

Options

No options available.

Usage

In solverDict file:

gapGas timeTabulated;

gapGasOptions
{
    #include "$FOAM_CASE/constant/gapGasHistories";

    //timePoints (0.05000       604.42270   920.17348);
    //gapPressures (4.37114e+06 5.68517e+06 9.65693e+06);
    //Ar (0.0   0.0 0.0);
    //He (1.0   0.99959 0.87012);
    //Kr (0.0   0.00006 0.01987);
    //Ne (0.0   0.0 0.0);
    //Rn (0.0   0.0 0.0);
    //Xe (0.0   0.00035 0.11001);

    timeInterpolationMethod linear;
}

In gapGas file inside the time step folder (e.g. 0/ or 500.25/uniform/, etc):

massFractions
{
    Ar 0;
    He 1;
    Kr 0;
    Ne 0;
    Rn 0;
    Xe 0;
};

gasPressure                     2.25e6;

If using an external file like "gapGasHistories" dictionary, then in this file:

timePoints (0.0 100 1000 );
gapPressures (4.37114e+06 5.68517e+06 9.65693e+06);
Ar (0.0 0.0 0.0);
He (1.0 0.99959 0.87012);
Kr (0.0 0.00006 0.01987);
Ne (0.0 0.0 0.0);
Rn (0.0 0.0 0.0);
Xe (0.0 0.00035 0.11001);
