Syntax¶

Defined in couplingProperties dictionary.

energyModels
(
    wallHeatTransferYagi
);
wallHeatTransferYagiProps
{
    QWallFluidName         "QWallFluid";
    QWallFluidCoeffNAme    "QWallFluidCoeff";
    wallTempName           "wallTemp";
    tempFieldName          "T";
    voidfractionFieldName  "voidfraction";
    voidfractionMax        scalar1;
    maxSource              scalar2;
    velFieldName           "U";
    densityFieldName       "rho";
    implicit               switch1;
    verbose                switch2;
}

QWallFluid = name of the wall-fluid heat transfer rate field
QwallFluidCoeff = name of the wall-fluid heat transfer coefficient field
wallTemp = name of the wall temperature field
T = name of the fluid temperature field
voidfraction = name of the finite volume void fraction field
scalar1 = maximum void fraction for a cell to be considered packed
scalar2 = (optional, default 1e30) maximum allowed source term
U = name of the finite volume fluid velocity field
rho = name of the fluid density field
switch1 = (optional, default true) activate to treat the fluid temperature implicitly
switch2 = (optional, default false) activate to write additional fields, and write cell-based data to the terminal

Examples¶

    QWallFluidCoeffNAme    "QWallFluidCoeff";
    wallTempName           "wallTemp";
    tempFieldName          "T";
    voidfractionFieldName  "voidfraction";
    voidfractionMax        0.5;
    velFieldName           "U";
    densityFieldName       "rho";
    implicit               true;
}

Description¶

The energy model performs calculation of wall-to-bed heat transfer for a packed bed, based on the correlation of Yagi and Wakao (1959).
